Is glycerol trioleate the same as any commercial material described as an oleic triglyceride?

Not necessarily. Triolein refers to the glycerol triester of oleic acid, whereas a commercial oleic triglyceride can contain a broader fatty-acid distribution. A generic description or a related synonym does not establish the same composition. Confirm the offered material’s identity basis, fatty-acid profile where relevant and batch specification before treating products as equivalent.

Which data are most useful when comparing glycerol trioleate for an oil-phase formulation?

Use the agreed specification rather than appearance alone. Acid value, water, colour, iodine value, saponification value and the related test methods can help distinguish grades and assess handling consistency. The proposed material should then be checked in the intended oil phase or finished formulation under the actual process conditions.

Does glycerol trioleate act as a standalone emulsifier in water-based systems?

It should not be assumed to do so. Glycerol trioleate is an oil-soluble triglyceride ester, and its role depends on the complete formulation, phase ratio and other surfactants if used. Assess its contribution in the intended system rather than selecting it solely from a generic “emulsifier” description.

Glycerol Trioleate (Triolein) CAS 122-32-7

Glycerol Trioleate (Triolein, CAS 122-32-7, EC 204-534-7) is the defined triester of glycerol and oleic acid, with the molecular formula C57H104O6. It is an oil-soluble ester raw material evaluated for lubricity, emollience and oil-phase compatibility in personal-care, lubricant, metalworking and specialty formulations. It is chemically distinct from commercial Glyceryl Monooleate (GMO). Select the supplied grade by assay or ester profile, acid value, iodine value, peroxide value, water, color and low-temperature behavior, then confirm the current physical form, packaging and application suitability against the TDS, COA and SDS.

Product overview

Glycerol Trioleate, also called Triolein or Glyceryl Trioleate (CAS 122-32-7, EC 204-534-7), is the triglyceride formed by esterifying glycerol with three molecules of oleic acid. It is an oil-soluble functional lipid and ester raw material rather than a high-HLB standalone emulsifier. In suitable formulations it can contribute lubricity, emollience, oil-phase compatibility and ester functionality in personal-care oils, lubricants, metalworking fluids, specialty chemical blends and research lipid systems. Buyers should match the supplied grade by assay or ester profile, acid value, iodine value, moisture, peroxide value, color, appearance and any application-specific limits. Confirm the applicable test methods and batch COA, then confirm current packaging, net weight, oxidation protection and low-temperature handling in the quotation. Review the current TDS and SDS before handling; a reference-grade SDS may not represent every commercial grade or impurity profile.
