DESCRIPTION AND CHEMICAL IDENTITY

Methyl Glucose Dioleate belongs to the methyl glucoside fatty acid ester family. The cosmetic name describes a diester of methyl glucoside and oleic acid rather than a polyethylene glycol ether.
The methyl glucoside portion of Methyl Glucose Dioleate contains a glucose-derived ring with hydroxyl functionality, while the oleate portions supply long hydrocarbon chains. Esterification connects these regions into a molecule capable of participating at an oil–water interface.
The chemical inventory entry D-glucopyranoside methyl 2,6-dioleate identifies a defined substitution pattern. A cosmetic ingredient reference also associates the broader dioleate name with another CAS number, so the identifier on the actual product documentation remains important.
The molecular formula and molecular weight above describe the defined diester structure. They do not establish that a commercial material is a single chromatographically pure positional isomer or that every product carrying the INCI name has an identical composition.

Commercial active content is another distinction. A Methyl Glucose Dioleate product described as 100% active is supplied without the dilution implied by a lower-active preparation, but that description is not automatically a declaration of 100% purity of one molecular species.
Methyl Glucose Dioleate is also different from methyl glucose sesquioleate, methyl glucose sesquistearate and methyl glucose isostearate. Changes in ester distribution or fatty acid identity can change physical form, polarity and application behavior.
For a Methyl Glucose Dioleate supply enquiry, the complete INCI name, CAS information and intended function provide a clearer starting point than a shortened reference to a glucose emulsifier. This is particularly useful where product names or catalogues group related esters and polyethers together.

MOLECULAR STRUCTURE AND FUNCTION

The methyl glucoside core of Methyl Glucose Dioleate provides oxygen-containing polar functionality. The two oleate ester groups provide two C18 fatty acyl chains, each containing the unsaturation associated with oleic acid.
In the idealized diester, esterification of two hydroxyl groups leaves other hydroxyl groups available on the glucoside core. This combination explains why the material has measurable hydroxyl functionality while remaining strongly compatible with oil phases.
The methyl group in methyl glucoside is part of the glycosidic structure. Methyl Glucose Dioleate should therefore not be confused with methyl oleate, which is the methyl ester of oleic acid and has a different molecular architecture.
Methyl Glucose Dioleate is described as nonionic because its principal functional groups do not make it an ionic surfactant salt. That description does not guarantee that every salt, acid, preservative or other ingredient is compatible with every formulation containing it.

The two fatty chains and relatively small polar region of Methyl Glucose Dioleate are consistent with its documented role as a low-HLB emulsifier. At an interface, that balance supports use in systems where oil forms the continuous phase around dispersed water droplets.
The oleate groups also distinguish it from a corresponding saturated fatty acid ester. However, a particular melting range, oxidation lifetime or finished-product sensory result cannot be calculated reliably from the word oleate alone.
Manufacturing literature describes transesterification of fatty acid methyl esters with methyl glucoside, as well as other esterification routes, for this ingredient family. The route and purification controls should be obtained from the supplier where they matter to a product requirement.

PHYSICAL AND CHEMICAL PROPERTIES

The following entries distinguish a defined molecular structure, published commercial-grade information and explicitly labeled theoretical calculations. They are not a combined specification for all Methyl Glucose Dioleate supplied by Ataman Chemicals.
Physical Form: Documented commercial Methyl Glucose Dioleate is an amber or yellow, viscous liquid.
Odor: Characteristic in a representative product specification. Odor quality should be compared with an appropriate reference rather than assigned a universal intensity.
INCI Identity: METHYL GLUCOSE DIOLEATE.
Defined Molecular Formula: C43H78O8.
Defined Molar Mass: Approximately 723.1 g/mol. This value is relevant to the idealized structure, not a substitute for commercial composition data.
Ionic Character: Nonionic.
HLB: A representative commercial listing gives an HLB range of 4.0–6.0. HLB is a formulation guide rather than a complete prediction of emulsion stability.
Active Content: One documented commercial product is described as 100% active. Confirm the composition of the offered grade, especially if it is a blend or a diluted preparation.
Oil Compatibility: Representative manufacturer information lists solubility in mineral oil, castor oil, isopropyl myristate, corn oil and other vegetable oils. This does not establish compatibility with every oil, silicone or solvent mixture.
Water Behavior: Do not assign the water-soluble surfactant-thickener behavior of PEG-120 Methyl Glucose Dioleate to this ingredient. Its documented low-HLB and oil-compatible character is the relevant starting point for formulation.
Acid Value: A representative commercial specification gives a maximum of 8 mg KOH/g, while historical typical-value information gives approximately 7 mg KOH/g.
Hydroxyl Value: A representative specification gives 140–165 mg KOH/g; historical typical-value information gives approximately 155 mg KOH/g.
Saponification Value: A representative specification gives 145–160 mg KOH/g; historical typical-value information gives approximately 155 mg KOH/g.
Iodine Value: A representative specification gives 60–75 g iodine per 100 g by the Hanus method; a historical typical value is approximately 68.
Moisture: A representative commercial specification gives a maximum of 0.5% by mass.
Color: A representative commercial specification gives a maximum of 8 on the Gardner scale; historical typical-value information gives approximately 7.
Specific Gravity: Approximately 1.01 is reported in historical product-related information. The unstated temperature basis limits its use in precise volumetric calculations.
Neat Viscosity: A numerical value with adequate test conditions was not verified. A finished cream's viscosity must not be presented as the viscosity of the ingredient used in that cream.
Melting and Boiling: No adequately supported numerical values are assigned here. Data for a related methyl glucose ester, polyether or finished formulation must remain associated with that material.
pH: No verified pH specification is assigned to the neat oil-compatible ester. Any result for an aqueous dispersion or a finished emulsion needs its own preparation and measurement conditions.
The listed analytical ranges belong to a documented commercial example. Confirm the current specification, methods and batch results for the actual product before using them as purchasing acceptance limits.
Several measurements describe different aspects of Methyl Glucose Dioleate. A matching appearance or HLB does not establish matching acidity, residual moisture, ester functionality or physical handling behavior.

INTERPRETING ANALYTICAL VALUES

Acid value measures the amount of base needed to neutralize acidic constituents under the specified test. It can indicate free acidity but is not by itself a complete assay of the dioleate structure.
Hydroxyl value measures hydroxyl functionality through its analytical procedure. It should be interpreted alongside the other values because changing esterification can affect the balance between free hydroxyl groups and ester groups.
Saponification value reflects the base consumption associated with saponifiable material under the method. It is useful for characterization but cannot alone distinguish every possible ester composition in a commercial product.

Iodine value describes unsaturation through the specified test. It is not a peroxide value, an antioxidant assay or a direct statement of how long a batch will remain acceptable during storage.
For the ideal diester, two ester groups and two remaining hydroxyl groups give calculated saponification and hydroxyl values near 155 mg KOH/g. These calculations use the defined molecular mass and the assumed functionality; they do not establish the composition of a batch.
The same idealized structure contains two olefinic double bonds, giving a calculated iodine value of approximately 70 g iodine per 100 g under a simple stoichiometric model. Agreement with a commercial range is informative, but the analytical method and actual ester mixture still govern measured results.
Water and color provide separate quality information. Neither should be used to infer that the acid value, ester distribution or oxidative condition has necessarily remained unchanged.

EMULSIFICATION AND FORMULATION ROLE

In a water-in-oil emulsion, water is dispersed as droplets within a continuous oil phase. Methyl Glucose Dioleate is documented as a primary emulsifier for this type of system, consistent with its relatively low HLB.
Emulsifier selection must also fit the actual oil blend, phase proportions and processing conditions. A suitable HLB range helps guide the work, but it does not replace formulation trials.
Methyl Glucose Dioleate can also contribute as part of an emulsifier blend. Published manufacturer formulations combine it with more hydrophilic emulsifiers and separate rheology modifiers, demonstrating that an ingredient's preferred function does not dictate the structure of every complete formulation containing it.

The emulsifier and the rheology system address related but different requirements. A thick product may still contain unstable droplets, while an adequately emulsified product may require a separate structuring ingredient to obtain its intended texture.
Likewise, dispersing a pigment is not the same task as forming an emulsion. The most useful concentration and combination of ingredients depend on which of those functions is required in the product.
Methyl Glucose Dioleate should therefore be assessed as a multifunctional formulation ingredient. Its value can come from combining an interfacial role with emolliency and slip rather than maximizing any single measurement.

APPLICATIONS

The strongest documented uses of Methyl Glucose Dioleate are in cosmetic emulsions, emollient systems and color cosmetics. The descriptions below explain the ingredient's role and the product features relevant to development without assigning a universal dosage or promising finished-product performance.

WATER-IN-OIL CREAMS AND LOTIONS

Methyl Glucose Dioleate is used as a primary nonionic emulsifier in water-in-oil skin products. It helps the formulation accommodate dispersed water within an oil-continuous structure while also contributing to the feel of the continuous phase.
This combination is useful where the developer needs both emulsion formation and a smooth, emollient application. The resulting texture depends on the complete oil phase, water loading and any structuring agents.
The liquid form of Methyl Glucose Dioleate can simplify incorporation compared with an emulsifier requiring melting, but the overall process may still need heating because of waxes or other solid ingredients. A liquid emulsifier alone does not establish that the complete product can be manufactured cold.
Development should assess the intended emulsion structure and changes during storage. Droplet behavior, separation, viscosity and application properties provide different information and should be considered together.
The water-in-oil designation does not itself establish waterproofness, occlusion or a particular moisturizing benefit. Those are properties or claims of the finished formulation and require their own evidence.

FACIAL, BODY AND HAND-CARE PRODUCTS

Methyl Glucose Dioleate is documented for creams, lotions and related skin-care formats. Its emollient function can support spreading and a smooth afterfeel in a suitable formulation.
The term satiny describes a sensory target rather than a numerical material property. Oil selection, wax content, humectants and the remaining formulation influence whether the final product feels light, rich, tacky or slippery.
For a facial product, evaluate application, afterfeel and compatibility with the other components. For body or hand care, the balance between spreading, residue and the desired product body may lead to a different selection.
Cosmetic ingredient references also describe skin-conditioning and humectant functions. Those functional descriptions should not be turned into a quantified skin-hydration claim without testing the finished product.
Methyl Glucose Dioleate is a supporting cosmetic ingredient rather than a complete moisturizing system. Product development still needs appropriate formulation stability, preservation and assessment for the intended use.

LIPSTICKS, LIP BALMS AND MOLDED STICKS

Methyl Glucose Dioleate is documented as a lubricant for the application of lipsticks, lip balms and other molded sticks. It can contribute slip within a composition containing oils, waxes and, where relevant, pigments.
This role differs from supplying the stick's principal solid structure. Wax balance and other structuring materials still determine important aspects of hardness, shape retention and temperature behavior.
A useful trial considers application and physical integrity together. A formulation that spreads easily must also retain the required strength, surface appearance and stability in its packaging.
The liquid ester Methyl Glucose Dioleate can be relevant during processing as well as application, but its benefit should be evaluated in the actual manufacturing arrangement. Changes in mixing, filling and cooling can alter the result even when the raw-material addition is unchanged.
For lip products, the grade and finished formulation must be assessed for that exposure and destination market. Cosmetic use in a lip format does not establish a general food-additive authorization or permission for unrestricted ingestion.

PIGMENT DISPERSION AND COLOR COSMETICS

Manufacturer information identifies Methyl Glucose Dioleate as a pigment dispersant in anhydrous and aqueous multiphase makeup products. Its role can be considered alongside its emulsifying and emollient contributions.
Dispersant selection depends on the pigment, its surface treatment and the liquid medium. A material suitable for one pigment blend may behave differently with a different powder surface or oil phase.
Methyl Glucose Dioleate should be evaluated against the required dispersion quality and product texture. Uniformity, agglomeration, color development and changes during storage are relevant observations.
The use of a dispersant does not replace the required mechanical dispersion process. Mixing or milling conditions and the order of incorporation remain important to the final result.
This application can be particularly useful when one ingredient contributes both dispersion and application slip. Any reduction in the number of other ingredients must nevertheless be demonstrated in the complete formulation rather than assumed from multifunctionality alone.

SUN-CARE AND AFTER-SUN FORMULATIONS

Sun care and after-sun products are documented application areas for Methyl Glucose Dioleate. Its role is associated with the emulsion, dispersion or sensory system selected for the particular formulation.
Methyl Glucose Dioleate should not be described as a UV filter simply because it appears in a sunscreen formulation. The protective performance belongs to the approved filter system and the evaluated finished product.
Where a formulation contains dispersed mineral particles, the suitability of a dispersion aid depends on the specific particle treatment and medium. An established pigment-dispersing function does not automatically establish optimum performance with every mineral sunscreen ingredient.
For after-sun products, emolliency and application can be relevant design targets. These functions do not support claims to treat burns or provide a therapeutic effect.
Assess storage stability, application and the claims required for the final format. Water resistance or a particular protection factor must not be inferred from the use of a water-in-oil emulsifier alone.

ANTIPERSPIRANTS, DEODORANTS AND OTHER PERSONAL-CARE FORMATS

Antiperspirant and deodorant products are listed among commercial application areas. The potential contribution depends on whether the product uses an emulsion, an oil-containing phase, a stick structure or another format.
Methyl Glucose Dioleate can support formulation properties such as emulsification or application slip. It is not the antiperspirant active or a demonstrated antimicrobial deodorant active by virtue of its chemical name.
Electrolytes, powders, waxes and other components may influence the formulation. Compatibility should be checked under the actual conditions rather than inferred only from the word nonionic.
Published application listings also include conditioners and wipes. These are starting points for product evaluation, not proof that the ingredient will provide identical deposition, stability or sensory behavior in every format.
For these uses, define the intended function clearly before selecting a grade or comparing alternatives. An emulsifier requirement, a dispersion requirement and a viscosity-building requirement can lead to different choices.

CO-EMULSIFIER USE IN COMBINED SYSTEMS

Recent manufacturer formulation examples include Methyl Glucose Dioleate in blends with PEG-20 Methyl Glucose Sesquistearate, fatty materials and a polymeric rheology system. Such examples demonstrate use within a coordinated formulation rather than as the sole determinant of emulsion properties.
The more lipophilic and more hydrophilic components serve complementary design purposes. Their combined behavior should be evaluated against the selected oil phase and target product structure.
Results from those examples belong to the entire formulation. In particular, a published lotion viscosity does not provide a measurement of the neat dioleate or prove that it supplies all the product's thickening.
For development, preserve the distinction between the emulsifier blend and the structuring system. This makes it easier to understand whether a change is affecting droplet stability, product body, application or several of those properties together.

DISTINCTION FROM PEG-120 METHYL GLUCOSE DIOLEATE

Methyl Glucose Dioleate and PEG-120 Methyl Glucose Dioleate are different INCI ingredients. The PEG-120 product contains polyoxyethylene functionality that is absent from the unethoxylated diester structure described here.
CAS 86893-19-8 and EC/list number 617-932-4 identify the PEG-120 material in reviewed chemical records. They should not replace CAS 82933-91-3 and EC 280-069-3 when describing the defined unethoxylated substance.
The PEG-120 derivative is associated with surfactant formulation and viscosity-building uses. Those characteristics cannot be assigned automatically to Methyl Glucose Dioleate simply because the longer name contains the same final words.
Physical form can also be misleading. A related ingredient may be sold as a solid, syrup or blend, so the presence of a liquid product does not by itself resolve the identity.
For purchasing, compare the full INCI declaration, CAS information and composition. A catalogue entry shortened to methyl glucose dioleate needs clarification if its documentation actually identifies a PEG-containing material.

GRADE SELECTION, COMPATIBILITY AND QUALITY

Selection of Methyl Glucose Dioleate should begin with the intended function and complete composition. For an emulsion, consider the phase structure and oil blend; for a stick, consider application and structural requirements; for a dispersion, consider the powder and liquid medium.
Compare acid, hydroxyl, saponification and iodine values using compatible methods. A single matching number cannot establish equivalence between ester products with different compositions.
Define color and odor requirements against the intended product. An amber liquid may be acceptable in one formula but influence the appearance of another, particularly where the target is a pale or transparent product.
The oleate-containing structure makes unsaturation relevant to quality control. Where oxidative condition matters, specify an appropriate assessment separately instead of treating iodine value as proof of freshness.

Review any solvent, carrier or additional constituent in the supply form. The same amount of a diluted preparation and a 100% active grade does not deliver the same amount of ester.
Naturally derived descriptions concern origin and manufacturing context, not automatic certification of every commercial batch. Claims about sourcing, natural-origin content or particular certification schemes should be supported by documentation for the actual grade.
Ataman Chemicals can be contacted with the full ingredient identity, application, required analytical limits and quantity. Matching these requirements with current documentation provides a practical basis for deciding whether a proposed supply is suitable.

STARTING FORMULATION APPROACHES FOR METHYL GLUCOSE DIOLEATE

The following examples illustrate how Methyl Glucose Dioleate can be evaluated during formulation and process development. These starting approaches are not validated commercial recipes, production instructions, or final formulations confirmed to comply with applicable regulations.
The suggested levels are illustrative starting points for preliminary laboratory trials. Methyl Glucose Dioleate is a nonionic, lipophilic ester of methyl glucoside and oleic acid, used for emulsification and emolliency. These examples concern the non-ethoxylated ingredient identified by the INCI name Methyl Glucose Dioleate. Raw material composition, ester distribution, oil compatibility, and processing conditions can significantly influence performance. Laboratory evaluation, stability testing, product safety assessment, and applicable regulatory checks are required for each application.
Unless otherwise stated, percentages are by weight of the complete finished formulation and assume an undiluted cosmetic-grade raw material. Check the supplied composition before calculating additions. When varying Methyl Glucose Dioleate, replace an equal weight of the designated carrier oil to maintain the stated phase balance. Keep all supporting ingredients and their selected levels constant throughout each comparison.

EXAMPLE 1: METHYL GLUCOSE DIOLEATE EMULSIFIER LEVEL SCREENING IN A WATER-IN-OIL CREAM

Objective: To determine how Methyl Glucose Dioleate affects emulsion formation, droplet distribution, viscosity, and resistance to separation in a water-in-oil cream.

Starting components:

Methyl Glucose Dioleate: approximately 1.0%, 2.0%, and 3.0%

Cetyl alcohol: an illustrative fixed level of approximately 1.5%

Compatible carrier oil blend, such as mineral oil / caprylic-capric triglyceride: sufficient to bring the complete external oil phase, including the emulsifier and cetyl alcohol, to 30.0%

Glycerin: approximately 3.0%

Magnesium sulfate heptahydrate: an illustrative fixed level of approximately 0.5%

Compatible preservative system: a fixed supplier-supported level, with efficacy to be verified

Demineralized water: sufficient to reach 100%, maintaining a total internal aqueous phase of 70.0%

Aqueous phase pH before emulsification: select a fixed setpoint within approximately 5.5–6.0, compatible with the preservative

Phase preparation temperature: approximately 70–75 °C, using one fixed setpoint sufficient to melt the structurant

The oil phase remains continuous in the intended water-in-oil system. These trial compositions do not guarantee stability, particularly at a high internal water content. Do not infer emulsion type from appearance alone.

Application approach:

Blend Methyl Glucose Dioleate with the carrier oils and cetyl alcohol, then heat until uniform.
Prepare the aqueous phase separately, dissolving glycerin and magnesium sulfate and incorporating the preservative according to its processing requirements.
Bring both phases to the selected emulsification temperature.
Add the aqueous phase gradually into the oil phase under controlled mixing, keeping the addition rate and shear history consistent.
Cool with suitable agitation and record any thickening, thinning, or separation.
Confirm the continuous phase using microscopy together with suitable conductivity or dilution tests.
Measure viscosity and droplet distribution after the same equilibration period, then compare separation during defined storage and temperature-cycle testing.
Select the Methyl Glucose Dioleate level only after evaluating physical stability and preservative efficacy in the complete formula.
Use hygienic equipment, splash protection, and suitable gloves when handling heated phases. Antimicrobial protection must be demonstrated even when the product has an external oil phase.

EXAMPLE 2: METHYL GLUCOSE DIOLEATE CO-EMULSIFIER SCREENING IN AN OIL-IN-WATER LOTION

Objective: To examine how Methyl Glucose Dioleate influences emulsion quality, application slip, afterfeel, and viscosity stability when combined with an established oil-in-water emulsifier.

Starting approach:

Methyl Glucose Dioleate: approximately 0.5%, 1.0%, and 2.0%

PEG-20 Methyl Glucose Sesquistearate: an illustrative fixed level of approximately 2.0% as the primary oil-in-water emulsifier

Cetearyl alcohol: approximately 2.0%, kept constant

Compatible emollient oil blend: sufficient to bring the complete oil phase, including both emulsifiers and cetearyl alcohol, to 20.0%

Glycerin: approximately 3.0%

Compatible preservative system: a fixed supplier-supported level, with efficacy to be verified

Demineralized water and required pH adjuster: sufficient to reach 100%

Final pH: select a fixed setpoint within approximately 5.0–6.0, compatible with all ingredients

Emulsification temperature, shear, addition sequence, and cooling profile: keep constant using the established lotion process

Methyl Glucose Dioleate serves as a lipophilic co-emulsifier and emollient in this comparison. Its presence does not replace the need for a suitable primary oil-in-water emulsifier. A separate control without the dioleate ester, replaced with carrier oil, can help establish its contribution.

Application approach:

Combine Methyl Glucose Dioleate, the primary emulsifier, cetearyl alcohol, and carrier oils.
Heat the oil and aqueous phases separately to the established processing temperature, such as approximately 70–75 °C for a compatible system.
Add the oil phase into the aqueous phase according to the selected oil-in-water process and homogenize consistently.
Cool under controlled agitation and add temperature-sensitive ingredients at their supported incorporation temperatures.
Adjust the final pH and batch weight, then allow the same equilibration period for every sample.
Confirm oil-in-water structure and measure droplet size, viscosity, appearance, and pH.
Compare instrumental spreading behavior and, after safety review, application slip, tack, and afterfeel under a defined sensory protocol.
Monitor viscosity drift and separation under defined stability conditions before choosing the Methyl Glucose Dioleate level.
Evaluate microbiological quality, preservative efficacy, and packaging compatibility separately. Handle hot emulsions with appropriate eye, hand, and splash protection.

EXAMPLE 3: METHYL GLUCOSE DIOLEATE EMOLLIENT LEVEL EVALUATION IN AN ANHYDROUS BALM STICK

Objective: To assess how Methyl Glucose Dioleate affects glide, product payoff, stick firmness, and oil migration in an anhydrous balm stick.

Starting approach:

Methyl Glucose Dioleate: approximately 0.5%, 1.5%, and 3.0%

Cosmetic wax blend: an illustrative fixed level of approximately 15.0%, with composition and grades kept constant

Castor oil: approximately 35.0%, kept constant

Caprylic-capric triglyceride: sufficient to reach 100%, replacing the variable amount of Methyl Glucose Dioleate

Compatible antioxidant: an illustrative fixed level of approximately 0.05%, included in the total formulation

Water, fragrance, flavor, and pigments: omit from the initial comparison

Melting temperature, mixing duration, filling temperature, mold dimensions, and cooling conditions: keep constant

This is an emollient screening base rather than a finished lip product. Select raw materials suitable for the intended application. If developed for lips, assess the complete product for that exposure; the screening design alone does not establish suitability.

Application approach:

Melt the selected wax blend with the fixed oil components at the lowest temperature that produces a uniform melt.
Add Methyl Glucose Dioleate and the balancing triglyceride, mixing until homogeneous.
Incorporate the antioxidant within its documented processing limits and minimize unnecessary hot holding.
Fill identical molds or containers at the same controlled temperature and cool consistently.
Condition every sample for the same period before measuring hardness, break resistance, and visible surface defects.
Measure product payoff and glide using a consistent application method or suitable instrument.
Inspect sweating, oil separation, shrinkage, and migration during defined temperature and storage tests.
Compare oxidation indicators, color, and odor during stability testing before selecting the Methyl Glucose Dioleate level.
Evaluate packaging interaction and microbiological risk even for an anhydrous product. Use suitable protection against burns from molten wax and follow the current raw material safety data sheets.

HANDLING AND STORAGE

Methyl Glucose Dioleate Handling: Use the current supplied SDS and appropriate workplace controls. Avoid unnecessary eye and skin contact and use equipment suitable for transferring a viscous liquid.
Methyl Glucose Dioleate Personal Protection: Select eye protection, gloves and work clothing for the task and foreseeable contact. Spraying or heating changes the exposure situation and requires an appropriate assessment.
Methyl Glucose Dioleate Storage: Keep containers closed and protect Methyl Glucose Dioleate from contamination and extreme temperatures. Obtain the grade-specific storage range rather than assigning a temperature limit taken from a related glucose ester or polyether.
Methyl Glucose Dioleate Heating: Where warming is needed for transfer, use the supplier's instructions and controlled equipment. The absence of a verified boiling point in this profile is not a basis for selecting a heating temperature.
Methyl Glucose Dioleate Compatibility: Use the supplied SDS to identify incompatible materials. Storage compatibility must be considered separately from deliberate incorporation into a validated formulation.
Methyl Glucose Dioleate Spill Control: Contain leakage, protect drains and recover material using suitable equipment or absorbent. Restrict access because oily residues can create a slipping hazard.
Methyl Glucose Dioleate Inventory: Follow the documented shelf life or retest arrangement and retain batch traceability. A retest period for one commercial grade should not be represented as a universal expiry period for the INCI ingredient.

FIRST-AID MEASURES

Methyl Glucose Dioleate Eye Contact: Rinse promptly with plenty of water, remove contact lenses if easy to do and continue rinsing. Obtain medical advice if irritation, pain or visual symptoms occur, and follow the supplied SDS.
Methyl Glucose Dioleate Skin Contact: Remove contaminated clothing as needed and wash the affected area with soap and water. Seek medical advice if a reaction develops or persists.
Methyl Glucose Dioleate Inhalation: Move the affected person to fresh air following exposure to mist or heated emissions. Obtain medical attention for breathing difficulty or persistent symptoms.
Methyl Glucose Dioleate Ingestion: Rinse the mouth and obtain advice appropriate to the amount and symptoms. Do not induce vomiting unless directed by a medical professional and never give anything by mouth to an unconscious person.
Methyl Glucose Dioleate Medical Information: Provide the actual Methyl Glucose Dioleate product label and SDS when seeking assistance. These general measures do not replace product-specific emergency instructions.

SAFETY AND PRODUCT CLAIMS

Cosmetic ingredient safety and occupational handling classification are different assessments. Use the supplied SDS for the raw material and the relevant safety evaluation for the finished cosmetic.
Published cosmetic safety literature includes reports of contact allergy involving Methyl Glucose Dioleate. It should therefore not be described as universally non-allergenic or guaranteed non-irritating on the basis of a mildness description.
The intended product category, exposure and overall formulation matter. A favorable ingredient function does not establish suitability for every eye-area, lip, infant-care or other specialized use.
Transport classification must be confirmed for the actual supply form. This profile does not assign a UN number or a transport exemption without verified grade-specific documentation.
Waste ester, contaminated absorbent and packaging should follow an appropriate disposal route. Do not infer environmental discharge acceptability from sugar-derived or naturally derived descriptions.

FREQUENTLY ASKED QUESTIONS

What is Methyl Glucose Dioleate?
Methyl Glucose Dioleate is the diester of methyl glucoside and oleic acid, used in cosmetics for functions including emulsification, emolliency, lubrication and pigment dispersion.

Is Methyl Glucose Dioleate the same as PEG-120 Methyl Glucose Dioleate?
No. PEG-120 Methyl Glucose Dioleate contains polyoxyethylene functionality and has a separate identity and formulation role.

What is the INCI name of Methyl Glucose Dioleate?
The INCI name is METHYL GLUCOSE DIOLEATE, without a PEG prefix.

Which CAS and EC numbers identify the defined 2,6-dioleate?
CAS 82933-91-3 and EC 280-069-3 identify D-glucopyranoside methyl 2,6-dioleate. Another CAS number is also associated with the broader cosmetic ingredient name, so confirm the supplied documentation.

Is Methyl Glucose Dioleate a water-in-oil emulsifier?
Yes, that is a documented primary use, consistent with the low HLB of a representative commercial grade.

Does Methyl Glucose Dioleate always produce a water-in-oil product?
No. The complete emulsifier blend, oil phase, phase proportions and process determine the finished system.

What HLB is reported for Methyl Glucose Dioleate?
A representative commercial listing reports 4.0–6.0. The value is a formulation guide and not a guarantee of stability.

Can Methyl Glucose Dioleate be used in lipsticks and lip balms?
Those are documented application areas, particularly for lubrication and application properties; the actual grade and finished product must still be suitable for that use.

Does non-oily emollient mean that Methyl Glucose Dioleate is an oil-free material?
No. That description refers to the sensory contribution in a formulation, while the ingredient itself is an oil-compatible fatty acid ester.

Is Methyl Glucose Dioleate a UV filter or antiperspirant active?
The use of Methyl Glucose Dioleate in sun care or antiperspirant formulations does not establish either active function. Its role concerns the formulation system.

Is Methyl Glucose Dioleate a general shampoo thickener?
Do not assign the established viscosity-building role of the PEG-120 derivative to this unethoxylated ingredient without specific formulation evidence.

Does 100% active mean 100% purity of one isomer?
Not necessarily. Active content describes the supply form and should be distinguished from a detailed compositional or purity analysis.

What do acid and hydroxyl values indicate?
They describe different analytical aspects of acidity and hydroxyl functionality and should be interpreted alongside other specification results.

Does iodine value measure oxidation damage?
It primarily describes unsaturation under its test method. It is not interchangeable with peroxide value or a direct freshness assessment.

Are the boiling point and neat viscosity of Methyl Glucose Dioleate specified here?
No numerical values were assigned because adequately supported grade-specific measurements with the necessary conditions were not verified.

What should be included in a Methyl Glucose Dioleate supply enquiry?
Provide the full INCI identity, intended function, application, analytical requirements, quantity, packaging needs and delivery destination.

TECHNICAL SUMMARY

Methyl Glucose Dioleate is a nonionic fatty acid ester whose cosmetic usefulness comes from combining a methyl glucoside-derived polar region with two oleate groups. The defined diester has formula C43H78O8 and an average molecular mass of approximately 723.1 g/mol. The specific 2,6-dioleate identity is associated with CAS 82933-91-3 and EC 280-069-3, while cosmetic references also associate the broader ingredient name with CAS 122703-32-6. The supplied documentation should connect the commercial material to the required identity.
The documented commercial behavior of Methyl Glucose Dioleate is consistent with a relatively lipophilic emulsifier. A representative product is an amber, viscous liquid with an HLB range of 4.0–6.0 and reported oil compatibility. Those characteristics support primary use in water-in-oil emulsions while also permitting a contribution within more complex emulsifier blends. HLB remains a screening tool: the oil phase, phase proportions, other ingredients and manufacturing process determine the actual emulsion and its stability.

Application value extends beyond emulsification. In skin-care products, Methyl Glucose Dioleate can contribute emolliency and smooth application; in lipsticks, balms and other molded sticks, lubrication can be relevant. Pigment dispersion is documented in anhydrous and multiphase makeup systems. Sun care, deodorants and other personal-care formats provide additional formulation contexts, but their active claims remain separate. The presence of the ester does not establish UV protection, antiperspirant activity, antimicrobial performance or a therapeutic effect.
Analytical characterization helps distinguish candidate grades of Methyl Glucose Dioleate. Published commercial ranges include acid value up to 8 mg KOH/g, hydroxyl value 140–165 mg KOH/g, saponification value 145–160 mg KOH/g and iodine value 60–75. Moisture and color add separate information about the supply. These values should be understood through their methods and contractual status, rather than combined into an assumed universal specification. Active content, detailed composition and purity are also different concepts and should remain clearly identified.

The idealized structure of Methyl Glucose Dioleate provides a useful consistency check on those measurements. Two ester groups and two remaining hydroxyl groups give calculated saponification and hydroxyl values near 155 mg KOH/g, while the two oleate double bonds correspond to a theoretical iodine value near 70. Those relationships help explain the published analytical pattern without proving the composition of an individual sample. Free acidity, water and any variation in ester composition require separate consideration, and an acceptable iodine value does not substitute for an assessment of oxidative condition.
The most important identity distinction is from PEG-120 Methyl Glucose Dioleate. Adding polyoxyethylene functionality changes the ingredient and its application behavior; the PEG-120 material's surfactant-thickening uses, physical data and identifiers cannot be transferred to the unethoxylated ester. Related sesquiesters and saturated fatty acid esters also require their own evaluation. Similar names do not establish replacement suitability, particularly when the formulation relies on a specific balance of interfacial function, liquid handling and sensory contribution.
Selection of Methyl Glucose Dioleate is strongest when it begins with a defined formulation task. Evaluate the emulsion or dispersion structure, application properties, storage behavior and the effect of the other ingredients together. Use current grade documentation for handling, transport and storage, and retain explicit uncertainty where a numerical property has not been verified. This approach allows useful technical detail without assigning invented boiling, melting, viscosity or density specifications.
