EBS Wax is a synthetic wax produced by the condensation reaction of stearic acid and ethylenediamine, forming a white to light yellow, odorless, hard and brittle waxy solid with a high melting point of 140–147°C that is non-toxic, insoluble in water at room temperature, stable to acids, alkalis, and aqueous media, and soluble in hot chlorinated hydrocarbons and aromatic solvents, widely used as an internal and external lubricant, release agent, anti-blocking agent, dispersant, and antistatic agent across plastics, rubber, coatings, inks, textiles, paper, asphalt, and personal care industries.
EBS Wax works by two distinct lubrication mechanisms: as an internal lubricant, the polar amide groups in its molecular structure insert into the polymer resin to reduce intermolecular interactions, improving melt flow and processing lubrication; as an external lubricant, EBS Wax migrates to the surface of the polymer melt to reduce friction between resin particles and processing equipment, preventing adhesion to metal surfaces and enabling clean mold release.
EBS Wax is a multifunctional processing aid that significantly reduces the coefficient of friction (μ ≤ 0.1), improves polymer melt flow index by 30–50%, delivers outstanding surface finish (Ra ≤ 0.2 μm), and provides effective performance at low addition rates of 0.1–1.0% by weight, making it a highly cost-effective additive for PVC, ABS, PS, PP, PE, PA, EVA, and engineering plastics.

EBS Wax has the IUPAC name N,N'-(Ethane-1,2-diyl)di(octadecanamide), a molecular structure containing two long C17 stearic acid chains connected through amide bonds to an ethylenediamine bridge, with two amide groups that provide strong polarity and lubricity while the two long aliphatic chains impart lipophilicity and waxy character, giving EBS Wax its unique dual internal/external lubricating properties and compatibility with a wide range of polar and non-polar polymer systems.
EBS Wax is available from multiple manufacturers including KLK OLEO (PALMOWAX EBS, derived from renewable vegetable oils, available in bead, powder, superfine, and atomized forms, HALAL and JHOSPA certified), and is classified under GHS as H315 (skin irritation), H319 (eye irritation), and H335 (respiratory irritation) with signal word Warning and precautionary statements P261 and P305+P351+P338.
EBS Wax has excellent thermal stability with a thermal decomposition temperature ≥250°C, a continuous service temperature range of -30°C to 200°C, volatile content <0.3% at 200°C/2h, and a flash point of approximately 280–285°C (Cleveland Open Cup), making it suitable for high-temperature polymer processing where many alternative lubricants degrade.
EBS Wax does not affect the thermal stability, appearance, color, or transparency of finished products when used at recommended addition levels, and provides low migration with minimal impact on mechanical properties — key advantages over traditional lubricants such as paraffin wax, polyethylene wax, and stearate-based lubricants which lack internal lubrication functionality.
Uses of EBS Wax:
EBS Wax is used as an internal and external lubricant in the processing of PVC (rigid and soft), ABS, PS, high-impact polystyrene (HIPS), PP, PE, nylon (PA 6, PA 66), EVA, polyolefin, acetal, phenolic resin, and amino plastics in injection molding, extrusion, calendering, and blow molding operations, where it accelerates melting, reduces melt viscosity, decreases extruder torque, saves processing energy, improves fluidity, extends mold service life, and gives products high surface smoothness and gloss.
EBS Wax is used as a mold release agent in injection molding and extrusion processes at 0.3–0.8% addition rate, where its migration to the polymer-metal interface reduces adhesion to mold and die surfaces, enabling easy and clean demolding of finished parts, particularly in the production of ABS, PC, PP, and PVC products including plastic shells for household appliances and engineering plastic components.
EBS Wax is used as an anti-blocking and slip agent in the production of PVC films, BOPP films, polyolefin films, and other polymer film products, providing a glossy finish, reducing surface tackiness, preventing film layers from sticking together during winding and storage, and improving unwinding and processing performance.
EBS Wax is used as a pigment dispersant in plastic masterbatch (color concentrate) production for ABS, PS, PP, polyester, and other polymer matrices at 0.5–5.0% addition, where it improves the wetting, dispersion, and uniform distribution of pigments and fillers in the polymer matrix, enhances color brightness and vibrancy, and reduces the amount of binder resin needed, resulting in cost savings.
EBS Wax is used in rubber processing as a lubricant, anti-sticking agent, release agent, filler surface modifier, and surface brightener; in natural rubber (NR) and synthetic rubber (SBR) compounds, EBS Wax at 1–3% reduces mixing power consumption and Mooney viscosity, improves silica dispersion (reducing Payne effect), improves curing characteristics, enhances mechanical properties, and imparts a high-gloss surface finish to rubber sheets, tubing, automotive floor mats, and drainage pipes.
EBS Wax is used as a sticky additive in asphalt production for bituminous materials, where it enhances adhesion of bitumen to aggregate materials, increases the softening point of bitumen, improves the compaction and workability of asphalt concrete mixtures, increases the melting point, decreases viscosity, and improves water and acid corrosion resistance; it is commonly used in formulations for cast asphalt concrete mixtures.
EBS Wax is used in coatings and paints at 0.5–2% addition to improve salt spray resistance, water resistance, and wet spray performance, promote uniform dispersion of pigments and fillers, improve surface leveling and smoothness of dried paint films, prevent paint peeling, enhance acid and alkali resistance, and function as a matting agent in nitrocellulose paints and furniture polishing agents.
EBS Wax is used in printing inks at 0.5–2% as a lubricant and anti-blocking agent to improve ink fluidity, prevent printed materials from sticking together during drying, improve printing quality and surface abrasion resistance (Taber abrasion ≤10 mg/1,000 cycles), prevent pigment settling (>6 months shelf stability), and improve spreadability and uniformity of ink on substrate surfaces.
EBS Wax is used in the textile industry as a lubricant for synthetic fiber spinning to reduce static electricity, improve yarn quality, impart soft and smooth hand feel to fabrics, and improve wear resistance and wrinkle resistance; it is also used as an antistatic agent at concentrations of approximately 33%.
EBS Wax is used in the paper industry as a coating additive to improve paper brightness, smoothness, water resistance, and printability, and as the main active ingredient in amide-based defoamers for paper pulping and papermaking processes.
EBS Wax is used in the leather industry as a fatliquoring agent and brightening agent to make leather soft and full, and to improve gloss and water resistance.
EBS Wax is used in the wire and cable industry as a lubricant in cable compound processing to improve insulation performance, surface finish, and cable processing efficiency; and in the metal wire drawing industry to increase extrusion speed, extend die service life, and improve surface brightness of iron wire.
EBS Wax is used in powder metallurgy as a forming agent and lubricant for metal powder compaction to improve powder flowability and formability and ensure more uniform green compact density.
EBS Wax is used in cosmetics and personal care products including lipsticks, lip balms, creams, and lotions as an emollient, thickening agent, and hardener that increases product hardness and gloss, improves skin feel, enhances spreadability (contact angle ≤30°), and reduces friction coefficient by approximately 40% for a silky skin feel.
EBS Wax is used in hot melt adhesives as a thickener and lubricant to increase melting point and improve bonding strength, and is used in adhesive and wax formulations to prevent caking and provide superior release performance.
EBS Wax is used in latex defoaming, fiber finishing operations, and foundry casting operations as a lubricant for resin-sand mixture compaction; it can also be used to improve the properties of the wax layer in paint remover formulations.
Benefits or Advantages of EBS Wax:
EBS Wax provides dual internal and external lubrication in a single additive — a key advantage over traditional single-function lubricants such as paraffin wax, polyethylene wax, and fatty acid stearates — with the internal lubrication reducing intermolecular friction and the external lubrication reducing polymer-equipment friction simultaneously.
EBS Wax has excellent thermal stability with decomposition temperature ≥250°C, flash point approximately 280–285°C, and volatile content <0.3%, making it more suitable for high-temperature polymer processing than lower-melting-point lubricants, with less tendency to thermal oxidation during processing and less color (yellowing) and odor contribution to the final product.
EBS Wax is effective at low addition rates of 0.1–1.0% by weight, with injection molding typically requiring only 0.3–0.8%, delivering excellent performance at minimal loading and without significant adverse effects on the mechanical properties, electrical properties, transparency, or thermal stability of the polymer product.
EBS Wax has good chemical resistance to acids, alkalis, and aqueous media, good water resistance, and good compatibility with polyolefins (PP/PE), engineering plastics (ABS/PC), and elastomers, maintaining consistent performance in both polar and non-polar systems across a wide range of processing temperatures.
EBS Wax derived from renewable vegetable oils (such as PALMOWAX EBS by KLK OLEO) offers a HALAL-certified, bio-based alternative with equivalent lubrication performance, supporting sustainable and certification-compliant formulations for sensitive market segments.
EBS Wax provides a significant synergistic effect when combined with other lubricants including zinc stearate, calcium stearate, PE wax, and paraffin wax, allowing formulation of customized lubricant systems with fine-tuned internal/external lubrication balance for specific polymer processing requirements.
Features of EBS Wax:
EBS Wax is a white to light yellow, odorless, hard and brittle waxy solid with a powdery substance that has a strong slippery feel, density of approximately 0.88–0.98 g/cm³ at 25°C, refractive index of approximately 1.467–1.475, and a melting point of 140–147°C at which it transitions to a low-viscosity liquid that flows easily.
EBS Wax is insoluble in water, methanol, ethanol, and most organic solvents at room temperature; soluble in high-boiling solvents such as xylene, chloroform, butanol, and hot aromatic and chlorinated hydrocarbons; and becomes wettable to water above 80°C; its vapor pressure is essentially zero at ambient temperature.
EBS Wax is available in multiple physical forms including powder (various mesh sizes including passes 200 mesh), granule (~1 mm bead), superfine powder, and atomized forms, providing flexibility for different compounding methods (direct addition during extrusion, premixing with resin, or premixing with pigments).
EBS Wax can also be used in emulsion form (EBS emulsion) for aqueous applications in latex defoaming, textile fiber finishing, paper coating, and water-based coating systems where the wax particles are dispersed in water for uniform application.
Chemical Properties of EBS Wax:
EBS Wax has the molecular formula C₃₈H₇₆N₂O₂, molecular weight 593.04 g/mol, and IUPAC name N,N'-(Ethane-1,2-diyl)di(octadecanamide); it is a diamide formed by the condensation of two molecules of stearic acid (C₁₇H₃₅COOH) with one molecule of ethylenediamine (H₂N-CH₂-CH₂-NH₂), releasing two molecules of water.
EBS Wax is chemically stable to acids, alkalis, and aqueous media at normal use temperatures; it has two polar amide groups (-CONH-) that provide compatibility with polar polymer surfaces and pigments, and two long nonpolar C₁₇ hydrocarbon chains that provide compatibility with nonpolar polymer matrices and waxy substrates, giving EBS Wax its unique amphiphilic character for dual lubrication.
EBS Wax is incompatible with strong oxidizing agents; it may cause mild skin irritation, eye irritation, and respiratory tract irritation on prolonged exposure to dust (GHS H315, H319, H335); it is stable to thermal oxidation under normal processing conditions and does not generate significant decomposition products below 250°C.
EBS Wax has a polar surface area of 40.62 Ų, LogP of approximately 15.0 (strongly lipophilic), surface tension of approximately 33.8 dyne/cm, ACD/BCF >1,000,000 (high bioaccumulation potential), and molar volume of approximately 667.6 cm³, consistent with its waxy, lipophilic, surface-active character.
Production of EBS Wax:
EBS Wax is produced commercially by the amidation (condensation) reaction of stearic acid with ethylenediamine in a controlled reactor under nitrogen atmosphere, using a composite acid catalyst system and antioxidant package, with the molar ratio of stearic acid to ethylenediamine approximately 1:0.58, reacting first at 100°C for 2 hours then at 180°C for 4 hours for dehydration, followed by discharge and solidification.
EBS Wax quality is controlled through verification of melting point (140–147°C), acid value (≤10 mg KOH/g), amine value (≤3 mg KOH/g), color (Gardner ≤3), volatile content (≤0.3%), and ash content (<0.1%), ensuring consistent lubrication performance and minimal interference with polymer color and thermal stability.
EBS Wax is produced in ISO 9001 and ISO 14001 certified facilities and is available in industrial grades, food-contact compliant grades, HALAL-certified grades (e.g., PALMOWAX EBS by KLK OLEO), and pharmaceutical/cosmetic grades with varying purity levels and particle size specifications.
