SOY WAX

At the molecular and crystallographic level, Soy Wax consists of a refined mixture of saturated and monounsaturated C16 to C18 triacylglycerols (triglycerides of empirical formula C53H102O6 to C57H110O6, average molecular weight 850 to 892 g/mol)—predominantly glyceryl tristearate (tristearin, C18:0), glyceryl palmitodistearate (C16:0/C18:0), and residual cis/trans-octadecenoate (C18:1) glycerides—often formulated with 2% to 15% w/w botanical monoglycerides and diglycerides to control polymorphic crystal habits. Produced by catalytic hydrogenation of refined, bleached, and deodorized (RBD) soybean oil (CAS 8001-22-7) over a nickel catalyst at 140 °C to 210 °C under 2 to 6 bar hydrogen pressure, the conversion of polyunsaturated linoleic (C18:2) and linolenic (C18:3) chains into saturated stearic acid (C18:0) lowers the Iodine Value from ~130 g I2/100 g down to 35–65 g I2/100 g in soft container-candle waxes and <= 4.0 g I2/100 g in fully hydrogenated soy stearin.

Formulators, candle engineers, and cosmetic chemists systematically prefer Soy Wax over petroleum-derived paraffin wax (CAS 8002-74-2), palm wax, and animal tallow stearin because 100% plant-based Soybean Wax burns 30% to 50% longer and cooler than paraffin wax with up to 90% less black petro-carbon soot, zero benzene/toluene combustion emissions, and effortless warm soap-and-water spill cleanup. Compared with unhydrogenated liquid soybean oil (which oxidizes rapidly into rancid aldehydes and sticky films) or brittle 100% palm stearin (which suffers from deforestation concerns and poor glass adhesion), Hydrogenated Soya Oil provides exceptional oxidative rancidity resistance, customizable polymorphic beta-prime crystal plasticity, skin-safe topical biocompatibility, and full Vegan, Halal, and Kosher compliance.

PRODUCT OVERVIEW, CHEMICAL IDENTITY AND OLEOCHEMICAL ARCHITECTURE

Soy Wax—registered globally under CAS Number 8016-70-4 (Soybean oil, hydrogenated; EC / EINECS Number 232-410-2) and CAS Number 68334-28-1 (Fats and Glyceridic oils, vegetable, hydrogenated; EC Number 269-820-6), with FDA UNII Code A2M91M918C and Cosmetic INCI designation HYDROGENATED SOYBEAN OIL—is a refined, catalytically hydrogenated vegetable triglyceride wax derived from the seeds of the soybean plant (Glycine max, also known botanically as Glycine soja). Known across international candle manufacturing, cosmetic formulation, pharmaceutical compounding, and paper-packaging industries by its synonyms Soybean Wax, Soya Wax, Hydrogenated Soya Oil, Soy Stearin, Vegetable Candle Wax, Sojae oleum hydrogenatum, and in Turkish chemical trade as Soya Mumu, Soya Wax, or Hidrojene Soya Yağı, this sustainable bio-based raw material is supplied by Ataman Kimya as creamy white to pale ivory flakes, pastilles (beads/pellets), micronized powders, or molded slabs.

First developed in the early 1990s (pioneered in 1991 by Michael Richards as a renewable, clean-burning agricultural alternative to costly beeswax and petrochemical paraffin wax), Soy Wax has grown into the dominant botanical wax in the global home-fragrance and personal-care markets. However, procurement specialists, candle technologists, and R&D chemists must clearly distinguish Soy Wax from three related soybean-derived materials that carry different CAS numbers and completely different chemical structures:

Distinction from Unhydrogenated Liquid Soybean Oil (CAS 8001-22-7, EC 232-274-4):
Native refined soybean oil is a polyunsaturated liquid vegetable oil at room temperature (pouring point -10 °C to -16 °C, Iodine Value 120 to 143 g I2/100 g) composed of approximately 50% to 56% linoleic acid (C18:2 cis-9,12), 21% to 25% oleic acid (C18:1 cis-9), 6% to 10% alpha-linolenic acid (C18:3 cis-9,12,15), 10% to 12% palmitic acid (C16:0), and 3.5% to 5.0% stearic acid (C18:0). Because of its high polyunsaturated content, native liquid soybean oil is a semi-drying oil that undergoes rapid free-radical autoxidation in air and cannot form a self-supporting solid wax. Soy Wax (CAS 8016-70-4) is produced by saturating those carbon-carbon double bonds with molecular hydrogen (H2), converting the liquid polyunsaturated triacylglycerols into solid, oxidation-resistant C18:0 stearoyl and C18:1 octadecenoyl triacylglycerols with a melting point between 42 °C and 70 °C.

Distinction from Epoxidized Soybean Oil (ESBO, CAS 8013-07-8, EC 232-391-0):
Buyers must never confuse Hydrogenated Soybean Oil (Soy Wax, CAS 8016-70-4) with Epoxidized Soybean Oil (ESBO, CAS 8013-07-8). ESBO is a viscous yellowish liquid manufactured by oxidizing the double bonds of soybean oil with hydrogen peroxide and formic/acetic acid into oxirane (epoxide) rings (oxirane oxygen content 6.0% to 7.0%), used exclusively as a secondary plasticizer and HCl-scavenging thermal stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a reactive liquid plasticizer and cannot be used in candle making or cosmetics.

Distinction Between 100% Pure Soy Wax and Botanical-Modified Soy Wax Grades:
Within commercial Soy Wax supply chains, grades are engineered along a precise hydrogenation and co-crystallization spectrum:
- 100% Pure Partially Hydrogenated Soy Wax (e.g., Golden Wax 415 / Pure Soy Flakes, CAS 8016-70-4): Consists of 100% partially hydrogenated soybean oil with zero additives, exhibiting a melting point of 49 °C to 52 °C (120 °F to 125 °F) and an Iodine Value of 45 to 58 g I2/100 g.
- Botanical-Modified Container Soy Wax Grades (e.g., Golden Wax 464, Golden Wax 444, NatureWax C-3, and CB-Advanced equivalents, CAS 8016-70-4 / 68334-28-1): Because 100% pure unblended hydrogenated soybean oil tends to recrystallize over time from metastable beta-prime (beta') microcrystals into coarse, chalky white beta (beta) spherulites ("frosting" or "bloom" on candle tops and glass walls), premium container-candle grades incorporate 2% to 12% w/w of soy-derived botanical modifiers—specifically distilled monoglycerides and diglycerides (glyceryl monostearate/palmitate, E471) or minor fractions of coconut/vegetable stearin. These polar glyceride crystal-habit modifiers lock the Soy Wax matrix into a smooth, creamy, crack-free beta-prime microcrystalline network, lower the pouring temperature window, improve glass jar adhesion, and allow fragrance oil loadings up to 10% to 12% w/w without oil sweating (syneresis).

- Pillar, Votive, Tart, and Wax-Melt Soy Wax Grades (e.g., Golden Wax 494 / BW-921 / Pillar Soy Wax equivalents): Formulated with a higher proportion of fully hydrogenated tristearin and botanical release enhancers (melting point 52 °C to 60 °C, Iodine Value 20 to 40 g I2/100 g) so that the cooled wax contracts slightly upon solidification (1.5% to 3.0% volumetric shrinkage), pulling cleanly away from silicone, polycarbonate, aluminum, or clamshell molds without sticking or crumbling.
- Fully Hydrogenated Soybean Oil (FHSO / Soy Stearin / USP-NF & Ph. Eur. Compendial Grade, CAS 8016-70-4): Hydrogenated to near-zero unsaturation (Iodine Value <= 4.0 to 5.0 g I2/100 g, C18:0 stearic acid content 84% to 90%, C16:0 palmitic acid 10% to 14%), producing a hard, brittle, snow-white waxy solid with a high slip melting point of 65 °C to 70 °C (149 °F to 158 °F) used as a candle hardener ("soy stearic additive"), a USP-NF pharmaceutical sustained-release tablet matrix and lubricant, and a high-stability cosmetic stick structurant.

POLYMORPHIC CRYSTALLIZATION PHYSICS (ALPHA, BETA-PRIME AND BETA POLYMORPHS)

To master candle pouring, cosmetic stick molding, and pharmaceutical lipid-matrix extrusion with Soy Wax (Hydrogenated Soybean Oil, CAS 8016-70-4), formulators must understand the triacylglycerol polymorphism that differentiates vegetable triglyceride waxes from simple hydrocarbon paraffin waxes.
Unlike petroleum paraffin wax (which consists of linear C20 to C40 alkane hydrocarbons that crystallize into simple orthorhombic or hexagonal plates), Soy Wax consists of three-pronged triacylglycerol molecules that pack in chair-like or tuning-fork conformations (2L double-chain-length or 3L triple-chain-length lamellar layers). When molten Soy Wax cools below its melting point, its triglyceride chains can crystallize into three distinct polymorphic crystal forms in order of increasing thermodynamic stability, packing density, and melting point:

The Alpha (alpha) Polymorph (Hexagonal Subcell, Least Stable, Lowest Melting):
When molten Soy Wax is shock-cooled rapidly (for example, pouring into an ice-cold jar or onto a chilled flaking drum), the hydrocarbon chains freeze into a disordered hexagonal subcell (alpha-form) with a wide inter-chain spacing of 0.415 nm (4.15 Angstroms) on X-Ray Diffraction (XRD). The alpha-polymorph is translucent, soft, and thermodynamically unstable, transforming within minutes to hours into the beta-prime form while releasing latent heat.

The Beta-Prime (beta') Polymorph (Orthorhombic Perpendicular Subcell, The Ideal Creamy Candle & Cosmetic Form):
Under controlled cooling and especially when asymmetric mixed-chain triglycerides (such as palmitodistearin C16/C18/C18) and 3% to 10% botanical monoglycerides/diglycerides are present, Soy Wax crystallizes into the orthorhombic perpendicular beta-prime (beta') polymorph (characteristic XRD short spacings at 0.380 nm and 0.420 nm). Beta-prime crystals grow as microscopic, interlocking needle-like spherulites (< 1 to 5 microns) that trap liquid unsaturated triglycerides and fragrance oil molecules uniformly inside a smooth, opaque, satin-creamy three-dimensional network. Every high-performance container candle and cosmetic balm aims to nucleate and stabilize the beta-prime crystal form!

The Beta (beta) Polymorph (Triclinic Parallel Subcell, Most Stable, Cause of "Soy Wax Frosting"):
The most thermodynamically stable crystal state for symmetrical C18:0 tristearin is the triclinic parallel beta (beta) polymorph (characteristic strong XRD short spacing at 0.460 nm / 4.6 Angstroms). Because beta-crystals pack with maximum density, they expel foreign molecules (including fragrance oils and oil-soluble dyes) and grow into large, coarse, brittle, chalky-white rosette crystals (20 to 100+ microns) that scatter light as white "frosting" (polymorphic bloom) or "cauliflower tops" on the surface and jar walls of soy candles!
How Candle Makers and Formulators Control Soy Wax Polymorphism in Practice:
- Tempering and Slush-Pouring (55 °C to 65 °C) vs. High-Temperature Pouring (68 °C to 75 °C): Depending on the exact grade of Soy Wax, pouring at the manufacturer's recommended window into pre-warmed jars (22 °C to 30 °C) in a draft-free room (21 °C to 24 °C) allows uniform beta-prime nucleation across the entire jar simultaneously.
- Avoiding Thermal Cycling During Storage: Storing finished Soy Wax candles in areas that fluctuate between cold nights (< 15 °C) and hot days (> 28 °C) accelerates the solid-state phase transition from beta-prime (beta') to coarse beta (beta) frosting. Note that frosting is a 100% natural, proof-of-botanical-purity crystallographic characteristic of pure Soy Wax and has zero negative impact on burn quality or scent throw!
- Using Botanical-Modified Grades (464 / 444 / C-3 Types) or 2%–5% Coconut/Beeswax Co-Modifiers: The monoglyceride and palmitic/lauric chain asymmetry built into Ataman Kimya's container Soy Wax grades sterically blocks C18:0 chains from aligning into triclinic beta lattices, preserving smooth, frost-resistant candle tops.

INDUSTRIAL MANUFACTURING PROCESS: SOYBEAN OIL REFINING, CATALYTIC HYDROGENATION AND FLAKING

The industrial manufacture of high-purity Soy Wax (CAS 8016-70-4 / 68334-28-1) from sustainably harvested Glycine max soybeans involves four integrated oleochemical unit operations:

Step 1 - Seed Extraction and RBD Refining (Degumming, Neutralization, Bleaching, and Deodorization):
Cleaned, dehulled, and flaked soybeans (containing ~18% to 20% crude oil) are extracted and the crude soybean oil is refined via water/acid degumming (removing hydratable and non-hydratable phospholipids/lecithin below 5 ppm phosphorus), alkali refining with dilute sodium hydroxide (neutralizing free fatty acids to < 0.05%), vacuum bleaching at 95 °C to 110 °C with acid-activated montmorillonite clay (removing chlorophyll, carotenoids, soap traces, and peroxide breakdown products), and high-vacuum steam stripping deodorization. Removal of phospholipids, sulfur compounds, and moisture is mandatory because phosphorus and sulfur poison nickel hydrogenation catalysts.

Step 2 - Selective Slurry-Phase Catalytic Hydrogenation (Hardening Reactor):
Refined, dry soybean oil is preheated to 140 °C to 160 °C inside a baffled, high-pressure 316L stainless-steel dead-end or loop hydrogenation autoclave equipped with gas-inducing turbine impellers and internal cooling coils. Finely divided supported Nickel catalyst (typically 0.02% to 0.15% w/w Ni supported on porous silica/kieselguhr) is suspended in the oil, and ultra-pure hydrogen gas (H2, >= 99.95% purity) is sparged at a gauge pressure of 0.15 to 0.60 MPa (1.5 to 6.0 bar).
Because catalytic hydrogenation of polyunsaturated fatty acids is strongly exothermic (releasing ~120 kJ per mole of C=C double bond saturated), reactor temperature rises to 170 °C to 210 °C and is controlled via internal cooling coils. Hydrogenation proceeds sequentially according to bond reactivity (k_linolenic > k_linoleic >> k_oleic):
- First, tri-unsaturated linolenic acid (C18:3, 9,12,15-octadecatrienoic acid) is hydrogenated to linoleic (C18:2) and isolinolenic isomers.
- Second, di-unsaturated linoleic acid (C18:2, 9,12-octadecadienoic acid) is hydrogenated to monounsaturated octadecenoic acid (C18:1 cis-oleic and trans-elaidic isomers).
- Third, monounsaturated C18:1 is hydrogenated into fully saturated stearic acid (C18:0, octadecanoic acid).

Process engineers track the reaction in real time by measuring the Refractive Index (nD60) and Solid Fat Content (SFC by pulsed NMR). When the target Iodine Value and Slip Melting Point are reached—for example, Iodine Value ~52 g I2/100 g and MP ~47 °C for container Soy Wax, or Iodine Value <= 2.0 g I2/100 g and MP ~68 °C for Fully Hydrogenated Soy Stearin—hydrogen flow is stopped and the molten batch is cooled to 85 °C to 95 °C.

Step 3 - Catalyst Filtration, Post-Bleaching, Botanical Blending, and Steam Deodorization:
The molten hydrogenated soybean oil is pumped through closed pressure-leaf filters pre-coated with diatomaceous earth, followed by citric-acid chelation and post-bleaching with activated earth and 0.5-micron polishing cartridge filters, stripping residual nickel below 0.2 to 1.0 ppm (mg/kg). For specialized Container and Pillar Candle grades, the molten base is precision-blended with botanical monoglycerides/diglycerides (E471) or fractionated vegetable stearins to lock in the target melting point, pouring window, and beta-prime crystal structure. The molten wax then passes through a continuous high-vacuum steam deodorizer (operating at 210 °C to 235 °C under 2 to 4 mbar absolute pressure with sparging steam), stripping volatile aldehydes, ketones, and free fatty acids (Acid Value <= 0.5 mg KOH/g) to yield an odorless, pale ivory-to-white molten wax.

Step 4 - Chilled-Drum Flaking, Pastillation (Rotoform), or Slab Molding:
Finally, the deodorized molten Soy Wax is solidified into user-friendly formats:
- Chilled-Drum Flaking: Molten Soy Wax at 60 °C to 75 °C is applied as a thin film onto a rotating internally chilled stainless-steel drum (surface temperature 8 °C to 15 °C) and scraped off by a doctor blade as crisp, fast-melting Soy Wax Flakes (thickness 0.8 to 1.8 mm, bulk density 450 to 560 g/L).
- Steel-Belt Pastillation: Molten Soy Wax is deposited via a rotating drop-former head onto a chilled stainless-steel cooling belt to form uniform, dust-free hemispherical Soy Wax Pastilles / Beads (diameter 3 to 5 mm, bulk density 520 to 620 g/L), which are packaged into moisture-lined 20 kg or 25 kg cartons and bags.

COMPREHENSIVE APPLICATIONS AND FORMULATION ENGINEERING

Thanks to its renewable vegetable origin, clean combustion chemistry, customizable melting point (42 °C to 70 °C), and dermatological mildness, Soy Wax supplied by Ataman Kimya is utilized across six major industrial sectors:

 Container Candles, Luxury Scented Jar Candles, and Aromatherapy Massage Candles:
Container candle manufacturing accounts for the largest global volume of partially hydrogenated Soy Wax (melting point 44 °C to 54 °C, Iodine Value 45 to 60 g I2/100 g, such as 464, 444, and C-3 equivalent grades):
- High Fragrance Payload (6.0% to 12.0% w/w): Because Soy Wax contains ester carbonyl groups (-COO-) and trace polar mono-/diglycerides alongside non-polar C16–C18 chains, its Hildebrand and Hansen solubility parameters match polar aromatic fragrance molecules (vanillin, coumarin, eugenol, benzyl benzoate, linalool, citrus terpenes, and musks) far better than purely non-polar alkane paraffin wax. Container Soy Wax holds 8.0% to 10.0% w/w (up to 12.0% w/w) fragrance oil without oil bleeding or surface sweating.
- Cooler Melt Pool and Extended Burn Time: Because Soy Wax has a higher specific heat capacity and latent heat of fusion (120 to 150 J/g) combined with a lower melting point (45 °C to 52 °C) than paraffin container wax, a Soy Wax candle burns 30% to 50% longer per gram than an equivalent paraffin candle while maintaining a wide, warm liquid melt pool that maximizes cold and hot scent throw.
- Warm-Pour Aromatherapy Massage Candles (Melting Point 42 °C to 46 °C): Because Cosmetic Grade Soy Wax is 100% skin-safe (INCI: HYDROGENATED SOYBEAN OIL) and melts just above human body temperature (37 °C), blending 70% to 85% w/w Low-Melt Soy Wax with 15% to 25% w/w Sweet Almond Oil, Jojoba Oil, Coconut Oil, or Shea Butter and 3% to 5% w/w skin-safe essential oils creates luxury massage candles whose warm liquid melt pool can be poured directly onto the skin as a silky, moisturizing massage oil!

 Pillar Candles, Votives, Wax Melts, Tarts, and Decorative Molded Candles:
For freestanding molded candles (pillars, sculptural spheres, ribbed columns, tapers, and votives) and wickless fragranced wax melts / clamshell tarts, Ataman Kimya supplies Harder Pillar & Tart Soy Wax grades (melting point 52 °C to 60 °C, needle penetration 15 to 30 dmm at 25 °C) as well as Fully Hydrogenated Soy Stearin (MP 66 °C to 70 °C):
- Mold Release & Shrinkage Control: Unlike container Soy Wax (which is engineered to adhere to glass walls), Pillar & Tart Soy Wax is formulated with higher tristearin crystallinity so that it contracts by 1.8% to 3.0% upon cooling, releasing effortlessly from silicone, metal, and PET/PVC clamshell molds with sharp geometric detail, high gloss, and snappy breakability.
- Soy Stearin Hardener Additive: Adding 5% to 20% w/w of Fully Hydrogenated Soybean Oil (FHSO, MP 66 °C to 70 °C) to soft container Soy Wax raises the blend melting point by 3 °C to 8 °C, increases structural hardness for summer shipping in hot climates (> 35 °C), and opacifies paraffin-soy hybrid blends ("parasoy").

 Cosmetics, Personal Care, Lip Balms, Deodorant Sticks, and Dermo-Cosmetics (INCI: HYDROGENATED SOYBEAN OIL):
In cosmetics and personal care formulation, Cosmetic Grade Soy Wax serves as a 100% plant-derived, vegan replacement for beeswax, lanolin, ozokerite, and microcrystalline petroleum waxes:
- Lip Balms, Lipsticks, and Solid Perfume Balms: Incorporated at 5.0% to 20.0% w/w alongside candelilla or carnauba wax, castor oil, and caprylic/capric triglyceride, Hydrogenated Soybean Oil builds creamy stick structure, prevents oil syneresis ("lip-stick sweating"), and provides a smooth, low-drag payoff that melts effortlessly upon contact with the lips (35 °C to 37 °C).
- Emulsion Creams, Body Butters, Lotions, and Hair Pomades: Dosed at 1.5% to 8.0% w/w into the oil phase of O/W and W/O emulsions, Soy Wax forms a shear-thinning lamellar/beta-prime oleogel network upon cooling that thickens creams and body butters, locks in moisture by reducing transepidermal water loss (TEWL), and stabilizes emulsions against high-temperature phase separation without greasy tackiness.
-Gentle Exfoliating Micro-Beads (Fully Hydrogenated Soy Wax Microspheres): Spherical spray-chilled microbeads (200 to 600 microns) of hard Fully Hydrogenated Soybean Oil (MP 68 °C) are used in facial scrubs and body polishes as a 100% biodegradable, non-microplastic exfoliating bead that gently polishes skin without micro-tearing.

 Pharmaceutical Excipients, Sustained-Release Matrices, and Tablet Lubrication (USP-NF / Ph. Eur.):
Under the official USP-NF monograph (Hydrogenated Soybean Oil) and European Pharmacopoeia monograph (Sojae oleum hydrogenatum), Fully Hydrogenated Soybean Oil (MP 66 °C to 70 °C, Iodine Value <= 4.0 to 5.0 g I2/100 g) is a workhorse compendial lipid excipient:
- Hydrophobic Sustained-Release Oral Matrix (10% to 40% w/w): Used in hot-melt extrusion (HME), melt granulation, spray congealing, and direct compression to encapsulate water-soluble APIs into controlled-release tablets and multiparticulate pellets that release drug slowly over 8 to 24 hours across the gastrointestinal tract.
- Tablet and Capsule Die-Wall Lubricant (0.5% to 3.0% w/w): Finely micronized FHSO powder (d50 < 20 to 40 microns) serves as a non-alkaline, metal-free tablet lubricant in formulations where magnesium stearate causes chemical degradation of amine- or ester-containing APIs.

 Paperboard Food Packaging Coatings, Crayons, Polishes, and Phase Change Materials (PCM):
- Biodegradable Moisture-Barrier Paper & Corrugated Board Coatings: Molten Soy Wax (alone or blended with rosin esters and EVA) is curtain-coated or roll-coated onto kraft paper, butcher paper, paper cups, and corrugated produce boxes as a PFAS-free, polyethylene-free, compostable hydrophobic water-vapor barrier that replaces petroleum paraffin wax coatings.
- Non-Toxic Crayons, Chalks, Leather/Wood Polishes, and Batik Wax: Used as a non-toxic, biodegradable binder in children's soy crayons, furniture and leather conditioning balms, ski waxes, and textile batik resist waxes.
- Bio-Based Phase Change Material (PCM) for Thermal Energy Storage: Because Soy Wax exhibits a high latent heat of fusion (120 to 190 J/g) and tunable phase-transition temperatures (42 °C to 68 °C) with zero supercooling and non-corrosive behavior, it is encapsulated in building wallboards, solar water-heating buffers, and thermal-management textiles.

 Practical Guide Formulation Frameworks Featuring Soy Wax:
- Guide Formulation 1 (High-Scent-Throw Single-Pour Container Candle, 250 g Glass Jar): Container Grade Soy Wax Flakes (464-Type, Melting Point 45 °C to 48 °C) 89.0% to 91.0% w/w, Premium Candle Fragrance Oil (flash point > 65 °C) 8.0% to 10.0% w/w, Botanical Coconut Wax or Glyceryl Monostearate Frost-Inhibitor Modifier (optional, already pre-blended in 464/C-3 grades) 1.0% to 2.0% w/w, and Oil-Soluble Liquid Candle Dye 0.05% to 0.20% w/w, wicked with a braided flat cotton coreless wick (CD / Stabilo or ECO series sized to jar diameter).
- Guide Formulation 2 (High-Release Clamshell Wax Melt & Molded Pillar Candle Blend): Pillar / Tart Grade Soy Wax Pastilles (494-Type, Melting Point 52 °C to 57 °C) 78.0% w/w, Fully Hydrogenated Soybean Oil (FHSO Soy Stearin Flakes, MP 68 °C) 10.0% w/w (for crisp mold release and snap hardness), Fragrance Oil 10.0% to 12.0% w/w, and Oil-Soluble Dye 0.1% w/w.

CANDLE ENGINEERING PROTOCOL: MELTING, FRAGRANCE BINDING, POURING, WICKING AND CURING

Because Soy Wax is a polymorphic triacylglycerol crystal system rather than a simple alkane hydrocarbon, achieving glass-smooth candle tops, full glass-wall adhesion ("zero wet spots"), a balanced edge-to-edge melt pool, and powerful cold and hot scent throw requires adherence to five quantitative candle-engineering protocols:

 Step 1 — Controlled Melting Temperature (80 °C to 85 °C / 176 °F to 185 °F):
Heat Soy Wax flakes or pastilles in a water-jacketed stainless-steel melter or double boiler to 80 °C to 85 °C (176 °F to 185 °F). Why must Soy Wax be heated to 82 °C–85 °C even though it melts at 46 °C–52 °C? Because solid Soy Wax retains microscopic "crystal memory" nuclei up to 75 °C; heating briefly to 82 °C–85 °C erases all prior beta crystal memory so the batch can nucleate freshly into uniform beta-prime microcrystals upon cooling. Crucially, NEVER heat Soy Wax above 90 °C to 95 °C (195 °F to 200 °F) or apply direct scorching flame, as prolonged overheating oxidizes trace unsaturated chains, causes yellow/amber discoloration, and triggers post-pour surface cracking!

 Step 2 — Fragrance Oil & Dye Addition Temperature (75 °C to 82 °C / 167 °F to 180 °F):
Add oil-soluble dyes and candle fragrance oil (typically 6.0% to 10.0% w/w; maximum 12.0% w/w) at 75 °C to 82 °C (167 °F to 180 °F), and stir gently and continuously for at least 2 to 3 full minutes without whipping air bubbles into the wax. Adding fragrance oil at too low a temperature (< 60 °C / 140 °F) prevents the polar fragrance molecules from integrating into the molten triglyceride matrix before crystallization begins, resulting in pockets of unbonded fragrance oil ("oil sweating" or "leaching" on the top of the cooled candle) and poor hot scent throw!

 Step 3 — Optimal Pouring Temperature and Container Pre-Warming (55 °C to 68 °C / 131 °F to 154 °F):
Cool the fragranced molten Soy Wax under gentle stirring to the grade-specific pouring window:
- For 464 / 444 Type Modified Container Soy Wax: Pour at 55 °C to 65 °C (131 °F to 149 °F).
- For C-3 Type Container Soy Wax: Pour at 65 °C to 74 °C (149 °F to 165 °F).
- For 415 Pure Soy Wax ("Slush Pour" Method): Cool to 38 °C to 43 °C (100 °F to 110 °F) until the wax just begins to turn slightly cloudy, then pour.
Pre-warm glass jars to 25 °C to 35 °C (77 °F to 95 °F), pour steadily down the center near the wick, and allow candles to cool slowly at a constant ambient room temperature of 21 °C to 24 °C (70 °F to 75 °F) on insulated racks (never directly on cold marble, steel, or concrete tables, and away from AC vents or drafts). Slow, uniform cooling prevents glass pull-away ("wet spots"), sinkholes around the wick, and surface frosting.

 Step 4 — Wick Selection and Sizing for Higher-Viscosity Molten Soy Wax:
Molten Soy Wax has a significantly higher dynamic viscosity (~30 to 40 mPa.s at 70 °C) and higher molecular weight (~875 g/mol) than molten paraffin wax (~5 to 8 mPa.s at 70 °C, MW ~350 g/mol). Because capillary action up the braided candle wick is inversely proportional to liquid viscosity (Lucas-Washburn equation), Soy Wax requires a larger, more open-braided wick—typically 1 to 2 sizes larger than an equivalent-diameter paraffin candle! Recommended wicks for Soy Wax include flat-braided coreless cotton wicks with paper filaments (CD / Stabilo series, ECO series, HTP series, or Premier 700 series) and natural booster wood wicks. Always perform a full burn test: the candle should achieve a full diameter melt pool (~6 to 12 mm deep) within 2 to 4 hours of burning (roughly 1 hour per 25 mm / 1 inch of jar diameter) without tunneling (wick too small) or mushrooming/smoking (wick too large).

 Step 5 — Mandatory Polymorphic Curing Time Before Burning (7 to 14 Days):
Unlike paraffin candles (which can be burned 24 hours after pouring), Soy Wax candles undergo continuous solid-state triacylglycerol polymorphic cross-linking and fragrance dispersion over 7 to 14 days at room temperature. Allowing Soy Wax candles to cure covered for 10 to 14 days before lighting increases hot scent throw intensity by 30% to 50% and ensures a stable, even burn rate!

TECHNICAL COMPARISON OF SOY WAX WITH ALTERNATIVE WAXES

Evaluating how Soy Wax (Hydrogenated Soybean Oil, CAS 8016-70-4) compares against competing mineral, plant, and insect waxes enables candle manufacturers and cosmetic chemists to design optimal pure or hybrid wax systems:

 Soy Wax vs. Petroleum Paraffin Wax (CAS 8002-74-2):
- Renewable Origin & Soot Emissions: Paraffin wax is a non-renewable petroleum-refinery distillate byproduct consisting of C20–C40 linear alkanes that emits black petro-carbon soot and trace aromatic hydrocarbons when burned improperly. Soy Wax is a 100% renewable, carbon-neutral agricultural crop derivative that burns cleanly with up to 90% less soot.
- Burn Duration & Shrinkage: Because Soy Wax has a higher density (0.92 g/cm3 vs. 0.90 g/cm3) and higher latent heat of fusion and specific heat, Soy Wax candles burn 30% to 50% longer than paraffin candles of identical weight. Moreover, paraffin shrinks by 12% to 17% upon cooling (requiring a second top-up pour to fill deep center sinkholes), whereas container Soy Wax shrinks by only 1.5% to 4.0%, enabling true single-pour production.
- Spill Cleanup: Spilled paraffin wax bonds stubbornly to carpets, upholstery, and glass, requiring solvent scraping; spilled Soy Wax is a biodegradable triglyceride that washes out completely with warm water and dish soap.

 Soy Wax vs. Palm Wax (Hydrogenated Palm Oil / Palm Stearin, CAS 68514-74-9):
Palm wax is a hard, brittle crystalline wax (rich in C16:0 palmitic acid) that forms feather- or crystal-patterned candles, but it suffers from zero glass adhesion, severe brittleness, lower fragrance retention (~5% to 7%), and intense consumer/retail scrutiny over tropical rainforest deforestation. Soy Wax offers creamy aesthetics, superior glass adhesion, 8% to 12% fragrance capacity, and abundant sustainable non-tropical cultivation.

 Soy Wax vs. Coconut Wax (Hydrogenated Coconut Oil, CAS 84836-98-6) and Rapeseed/Canola Wax:
Coconut wax (rich in C12:0 lauric and C14:0 myristic triglycerides) is ultra-white and frost-free, but pure coconut wax has a very low melting point (30 °C to 38 °C), making it too soft to use alone in candles or summer climates and costing 2.5 to 4 times more per kilogram than Soy Wax. In luxury candle making, blending 80% to 90% Soy Wax with 10% to 20% Coconut Wax ("Coco-Soy") combines the structural body and economy of Soy Wax with the ultra-smooth, frost-free surface of Coconut Wax!

 Soy Wax vs. Natural Beeswax (Cera Alba, CAS 8012-89-3):
Beeswax (a complex ester of C24–C34 fatty acids and fatty alcohols, MP 62 °C to 65 °C) is an animal/insect-derived product that is 4 to 6 times more expensive than Soy Wax, carries a natural honey odor that clashes with delicate perfumes, and is excluded from certified Vegan products. Soy Wax is 100% Vegan, neutral in odor, and far more cost-effective (while blending 3% to 5% beeswax into non-vegan Soy Wax is a classic trick for hardening tops).

PACKAGING, STORAGE AND HANDLING GUIDELINES

To preserve the creamy ivory-to-white color, neutral odor profile, low peroxide value, and free-flowing flake or pastille morphology of Soy Wax (Hydrogenated Soybean Oil, Soybean Wax, Soya Wax, CAS 8016-70-4 / 68334-28-1), warehouse managers and production operators should follow the storage and handling protocols established by Ataman Kimya.

Commercial Packaging Configurations Supplied by Ataman Kimya:
- 20 kg and 25 kg Net Polyethylene-Lined Corrugated Cartons (Boxes): Heavy-duty double-wall export cartons lined with a food/cosmetic-grade low-density polyethylene (LDPE) moisture- and odor-barrier inner bag containing free-flowing Soy Wax Flakes or Pastilles (standard palletization: 32 to 40 cartons = 800 kg to 1,000 kg net on shrink-wrapped ISPM-15 pallets).
- 20 kg and 25 kg Net Multi-Wall Kraft Paper or Woven Polypropylene Bags: Fitted with an internal polyethylene moisture liner for high-volume candle and industrial plants.
- 500 kg to 900 kg Flexible Intermediate Bulk Containers (FIBCs / Big Bags) and Heated Insulated Stainless-Steel Road Tankers: Available for automated industrial candle, paper-coating, and oleochemical facilities.
Storage Conditions and Thermal / Oxidative Protection:

 Cool, Dry, Temperature-Controlled Warehouse Storage (10 °C to 27 °C / 50 °F to 80 °F): Because container-grade Soy Wax has a low slip melting point (42 °C to 52 °C / 108 °F to 126 °F) and begins to soften plasticly (solid fat index drop) at temperatures above 32 °C to 35 °C (90 °F to 95 °F), storing cartons or bags of Soy Wax Flakes in hot summer warehouses (> 35 °C), uninsulated shipping containers parked in direct sunlight, or adjacent to steam boilers will cause the flakes or pastilles to soften, sinter, and fuse into a solid block ("blocking"). Therefore, always store Soy Wax in a cool, dry, well-ventilated indoor warehouse maintained between 10 °C and 27 °C (maximum 30 °C) and relative humidity below 65%, away from direct UV sunlight, radiators, and roof heat. Avoid stacking pallets more than two high in warm weather to prevent pressure blocking of the bottom cartons.

 Protection Against Odor Pickup and UV Autoxidation: Like all refined vegetable triglyceride lipids, high-surface-area Soy Wax Flakes can slowly absorb strong foreign odors from the surrounding air if stored in open bags next to volatile solvents, essential oils, fuels, or spices, and prolonged UV light exposure can slowly elevate peroxide values. Always keep the inner LDPE liner bag tightly twisted or sealed after partial dispensing, and rotate stock on a First-In, First-Out (FIFO) basis. When stored unopened in its original sealed packaging at 10 °C to 25 °C away from light and heat, Soy Wax maintains full specification compliance for 24 to 36 months (2 to 3 years) from the date of manufacture.
Industrial Melting, Material Compatibility, and Spill Cleanup Procedures:

In industrial melting tanks and transfer lines, melt Soy Wax using thermostatically controlled warm-water jackets, low-pressure steam coils, or low-watt-density indirect thermal oil heaters held between 65 °C and 85 °C. Never use high-watt-density direct immersion electric elements (> 150 °C surface skin temperature), which scorch Hydrogenated Soybean Oil into yellow/brown acrolein-containing tars. Use 304 or 316L stainless steel, aluminum, glass, or enameled vessels; never melt Soy Wax in unlined copper, brass, bronze, or rusty carbon-steel tanks, as trace dissolved copper (Cu2+) and iron (Fe3+) ions act as potent pro-oxidants that turn Soy Wax yellow-orange and accelerate rancidity!
If molten Soy Wax is spilled onto factory floors, allow it to cool and solidify, scrape up the solid Soybean Wax cleanly with a non-sparking plastic or metal spatula into waste containers, and scrub the residual lipid film with hot water (55 °C to 65 °C) and alkaline dish/floor detergent to eliminate slip hazards.

FIRST AID MEASURES, TOXICOLOGY AND SAFETY INFORMATION

Soy Wax (Hydrogenated Soybean Oil, Soya Wax, CAS 8016-70-4 / 68334-28-1) is a non-toxic, edible-oil-derived, biocompatible vegetable wax that is NOT classified as a hazardous substance or hazardous mixture under European Union Regulation (EC) No 1272/2008 (CLP) or the UN Globally Harmonized System (GHS). In its solid state at ambient temperature, Soy Wax poses virtually zero chemical hazard; in industrial manufacturing, safety precautions focus primarily on preventing thermal skin or eye burns from hot molten Soy Wax (60 °C to 90 °C) and avoiding overheating above its smoke/flash point (> 200 °C to 280 °C).

First Aid Measures for Exposure to Soy Wax:
- Contact with Hot Molten Soy Wax (Skin Burns): Solid Soy Wax flakes at room temperature are completely non-irritating and soothing to human skin (widely used in massage candles and lip balms). However, if hot molten Soy Wax (above 60 °C to 85 °C) splashes onto the skin, immediately cool the affected area under gently running cold tap water for at least 10 to 15 minutes to dissipate thermal heat from the solidified wax layer. Do NOT forcefully peel or rip hot solidified Hydrogenated Soybean Oil off burned or blistered skin; once cooled completely, the soft vegetable wax lifts off easily with warm soapy water or mineral/vegetable oil. Seek medical attention if second- or third-degree thermal blistering occurs.

- Eye Contact with Soy Wax: If solid dust or flakes of Soy Wax enter the eyes, do not rub the eyes; flush gently with lukewarm potable water or sterile isotonic saline eyewash solution for 10 to 15 minutes until the particle is removed. If hot molten Soy Wax splashes into the eye, flush immediately with cool-to-lukewarm water for 15 minutes and obtain immediate ophthalmological care for thermal burn evaluation.

- Inhalation of Soy Wax Vapors or Overheated Fumes: Under normal melting and candle-pouring temperatures (55 °C to 85 °C), Soy Wax is non-volatile (vapor pressure < 10^-6 Pa) and emits zero hazardous vapors. If a melting kettle malfunctions and overheats Soy Wax past its smoke point (195 °C to 235 °C), thermal pyrolysis of triglycerides releases irritating white smoke containing acrolein, volatile fatty acids, and carbon monoxide. Immediately shut off heat, ventilate the area, move any exposed workers into fresh air, and seek medical attention if coughing or respiratory irritation persists.

- Ingestion of Soy Wax: Hydrogenated Soybean Oil is an FDA GRAS-affirmed food ingredient (21 CFR 184.1555) with an oral LD50 in rats > 10,000 to 20,000 mg/kg body weight (practically non-toxic). If small quantities of unfragranced Soy Wax are accidentally swallowed, rinse the mouth with water; no emergency intervention is required. If large quantities of fragranced candle wax are ingested, do not induce vomiting and consult a physician.

- Note on Soy Protein Allergenicity: Refined, bleached, hydrogenated, and high-vacuum steam-deodorized Soy Wax (Hydrogenated Soybean Oil) consists of > 99.9% pure lipid triacylglycerols from which water-soluble soybean proteins have been completely removed during alkali refining, clay bleaching, filtration, and 220 °C deodorization (exempt from major food allergen labeling under EU Regulation 1169/2011 Annex II and U.S. FALCPA for highly refined soybean oil derivatives).

Personal Protective Equipment (PPE) and Fire-Fighting Measures:
When handling solid Soy Wax bags, standard safety glasses (EN 166), clean work gloves, and slip-resistant shoes are sufficient. When handling hot molten Soy Wax (> 65 °C), wear splash-proof safety goggles, heat-resistant insulated gloves (EN 407), and long-sleeved cotton workwear.
Fire-Fighting Measures for Molten Wax Fires: Soy Wax has a high Open-Cup Flash Point (> 280 °C to 315 °C), meaning it will not ignite unless heated to extreme temperatures. In the event of an overheated wax kettle fire (Class B / Class K grease/oil fire), NEVER pour water or use a solid water jet onto burning molten Soy Wax! Water sinks beneath the lighter molten wax (density ~0.86 g/cm3) and flashes instantaneously into steam (expanding 1,700-fold), causing a violent boil-over fireball! Extinguish molten Soy Wax fires by smothering with a fire blanket, dry chemical powder (ABC/BC), carbon dioxide (CO2), alcohol-resistant foam, or a Class K wet-chemical extinguisher.

FREQUENTLY ASKED QUESTIONS (FAQ)

 What is Soy Wax and how is it chemically manufactured from soybeans?
Soy Wax (chemically designated as Hydrogenated Soybean Oil, CAS 8016-70-4 / 68334-28-1, EC 232-410-2, INCI: HYDROGENATED SOYBEAN OIL) is a 100% renewable vegetable triglyceride wax manufactured from Glycine max soybean seeds. After crude soybean oil is extracted, degummed, alkali-refined, clay-bleached, and deodorized, the liquid oil (Iodine Value ~130 g I2/100 g) undergoes catalytic hydrogenation with pure hydrogen gas (H2) at 140 °C to 210 °C over a supported nickel catalyst, converting polyunsaturated linoleic (C18:2) and linolenic (C18:3) fatty acid chains into saturated stearic acid (C18:0) and monounsaturated C18:1 chains that solidify at room temperature into a creamy white wax with a melting point between 42 °C and 70 °C.

 What is the difference between Container Soy Wax (464/444/C-3 types), Pillar/Tart Soy Wax (494 type), and Fully Hydrogenated Soybean Oil (FHSO)?
Container Soy Wax grades (melting point 45 °C to 52 °C, Iodine Value 45 to 60 g I2/100 g, needle penetration 35 to 60 dmm) are softer, partially hydrogenated grades formulated with botanical mono-/diglyceride crystal modifiers to adhere smoothly to glass jars with minimal shrinkage (1.5% to 3.0%) and hold 8% to 12% fragrance oil. Pillar and Wax-Melt/Tart Soy Wax grades (melting point 52 °C to 60 °C, Iodine Value 20 to 38 g I2/100 g, penetration 15 to 30 dmm) contain higher tristearin crystallinity so they contract cleanly from silicone, metal, and clamshell molds without sticking. Fully Hydrogenated Soybean Oil (FHSO / Soy Stearin, melting point 66 °C to 70 °C, Iodine Value <= 4.0 g I2/100 g) is a hard, brittle C18:0 tristearin wax used at 5% to 20% as a candle hardener or as a USP-NF pharmaceutical sustained-release matrix excipient.

 Why does Soy Wax sometimes develop white "frosting" or rough tops after cooling, and how can it be prevented?
Because Soy Wax is a natural triacylglycerol lipid rather than a petroleum alkane, its molecules exhibit polymorphism—crystallizing into alpha, beta-prime (beta'), and beta (beta) crystal lattices. "Frosting" (white crystalline bloom on candle surfaces or jar walls) occurs when smooth microcrystalline beta-prime crystals slowly rearrange into larger, denser triclinic beta crystals. Frosting does not affect burn performance at all and is actually proof of 100% natural soy purity; it can be minimized by using botanical-modified container Soy Wax grades (such as 464 or C-3 equivalents), pouring at the exact recommended temperature (55 °C to 65 °C) into pre-warmed jars, cooling in a draft-free room at 21 °C to 24 °C, or blending 5% to 15% coconut wax.

 At what temperatures should Soy Wax be melted, mixed with fragrance oil, and poured when making candles?
For standard container Soy Wax (such as 464/444/C-3 types), heat the wax flakes to 80 °C to 85 °C (176 °F to 185 °F) to completely erase prior crystal memory without exceeding 90 °C (which causes yellowing). Add fragrance oil (6% to 10% w/w) and dye at 75 °C to 82 °C (167 °F to 180 °F)—never below 60 °C, so the fragrance binds molecularly into the molten triglyceride network without sweating out—stir gently for 2 to 3 minutes, and pour at 55 °C to 65 °C (131 °F to 149 °F) into clean, pre-warmed jars, followed by a 7- to 14-day curing period before lighting.

 Why do Soy Wax candles require a larger wick size than paraffin wax candles of the same diameter?
Molten Soy Wax has a higher dynamic viscosity (~30 to 40 mPa.s at 70 °C) and higher molecular weight (~875 g/mol) than molten petroleum paraffin wax (~5 to 8 mPa.s at 70 °C, MW ~350 g/mol). Because capillary upward flow through a braided cotton wick is slower for more viscous liquids, Soy Wax requires a flat-braided coreless cotton wick (such as CD/Stabilo, ECO, or HTP series) or wooden wick that is 1 to 2 sizes larger than a paraffin candle of the same jar diameter to achieve a full edge-to-edge melt pool and prevent tunneling.

 What is the difference between Soy Wax (CAS 8016-70-4), Liquid Soybean Oil (CAS 8001-22-7), and Epoxidized Soybean Oil (ESBO, CAS 8013-07-8)?
Liquid Soybean Oil (CAS 8001-22-7) is the unhydrogenated polyunsaturated liquid vegetable oil (Iodine Value ~130 g I2/100 g) that remains liquid down to -12 °C. Soy Wax (Hydrogenated Soybean Oil, CAS 8016-70-4) is the solid waxy triglyceride produced by hydrogenating the double bonds of soybean oil to raise its melting point to 42 °C–70 °C. Epoxidized Soybean Oil (ESBO, CAS 8013-07-8) is a chemically oxidized liquid containing oxirane epoxide rings used solely as an industrial PVC plasticizer and heat stabilizer, and must never be confused with Soy Wax.

 How can quality-control laboratories verify that a Soy Wax shipment is 100% pure vegetable wax and not adulterated with petroleum paraffin wax?
Laboratory verification relies on Saponification Value (AOCS Cd 3-25 / ISO 3657) and Unsaponifiable Matter (AOCS Ca 6a-40 / ISO 3596). Because pure Soy Wax consists of saponifiable fatty acid glyceride esters, it exhibits a Saponification Value of 185 to 200 mg KOH/g and an Unsaponifiable Matter content of <= 0.8% to 1.5% w/w. Petroleum paraffin wax consists of non-saponifiable hydrocarbons (Saponification Value = 0 mg KOH/g); therefore, if a wax is adulterated with even 10% to 30% paraffin wax, its Saponification Value drops proportionally below 165 mg KOH/g and its Unsaponifiable Matter spikes to 10%–30% w/w.

 Why is Low-Melt Cosmetic Grade Soy Wax ideal for warm-pour aromatherapy massage candles and vegan lip balms?
Cosmetic Grade Soy Wax (INCI: HYDROGENATED SOYBEAN OIL, melting point 42 °C to 48 °C) melts just above human skin temperature (37 °C), is dermatologically non-irritating and non-comedogenic, and is rich in skin-conditioning stearic and oleic glycerides. When blended with 15% to 25% sweet almond, jojoba, or coconut oil in a massage candle, the warm liquid melt pool (~43 °C to 46 °C) can be poured directly onto the skin as a soothing massage oil without burning, and in lip balms (at 10% to 20% w/w) it provides vegan stick structure with silky glide.

 Why must water never be used to extinguish an overheated molten Soy Wax kettle fire?
Molten Soy Wax is a hydrophobic lipid oil with a liquid density of ~0.86 g/cm3 (lighter than water at 1.00 g/cm3) and an Open-Cup Flash Point above 280 °C. If liquid water is poured onto burning molten Soy Wax (> 280 °C), the water sinks to the bottom of the hot kettle and vaporizes explosively into steam (expanding 1,700 times in volume), violently ejecting burning molten wax out of the vessel. Always extinguish molten wax fires by turning off the heat and smothering with a fire blanket, dry chemical powder (ABC/BC), CO2, foam, or a Class K wet-chemical extinguisher.
