    Product Overview

    Glycerol Trioleate CAS 122-32-7, also known as Triolein, is supplied as a triglyceride ester based on glycerol and oleic acid. It is more suitable to position this product as an oil-soluble ester raw material rather than as a standalone emulsifier product, because its main value lies in oil-phase compatibility, lubricity, emollient performance, and ester functionality in formulated systems.

    This material is commonly applied in personal care oil systems, lubricant and metalworking formulations, specialty ester processing, and research-related lipid applications. Technical documents such as COA, TDS, and SDS may be provided according to the supplied grade.

    FAQ - Technical & Supply Chain

    • Q:

      What is the chemical structure of Glycerol Trioleate CAS 122-32-7?

      A: Glycerol Trioleate (CAS 122-32-7) is a triglyceride ester formed from one molecule of glycerol esterified with three molecules of oleic acid (C18:1 unsaturated fatty acid). Its molecular formula is C57H104O6 with a molecular weight of 885.4 g/mol, confirmed by the EINECS registration number 204-534-7.
    • Q:

      What are the key quality specifications for Glycerol Trioleate?

      A: Typical quality parameters for Glycerol Trioleate include ester content ≥99%, acid value ≤2 mg KOH/g, iodine value 80-90 g I2/100g, and moisture content ≤0.5%. The product is supplied as a colorless to pale yellow transparent oily liquid with a melting point of approximately -4°C to -5°C.
    • Q:

      How does the fatty acid composition of Glycerol Trioleate affect its applications?

      A: The high oleic acid (C18:1) content gives Glycerol Trioleate excellent oxidative stability compared to polyunsaturated triglycerides such as linseed oil. Its monounsaturated nature provides low-temperature fluidity (melting point -4°C to -5°C) while maintaining the hydrophobic and lubricating properties required for oil-phase formulations.
    • Q:

      What are the primary industrial applications of Glycerol Trioleate?

      A: Glycerol Trioleate is primarily used as an oil-soluble emollient in personal care formulations, a biodegradable lubricity additive in metalworking fluids and industrial lubricants, and a functional triglyceride ester in specialty chemical processing. It is also used in lipid research as a model triglyceride compound.
    • Q:

      What are the solubility characteristics of Glycerol Trioleate?

      A: Glycerol Trioleate is soluble in ether, chloroform, hexane, and most non-polar organic solvents, but insoluble in water. Its oil solubility makes it an excellent candidate for oil-phase formulations in personal care products and as a lubricant base in non-aqueous systems.
    • Q:

      Is Glycerol Trioleate compatible with other formulation ingredients?

      A: Glycerol Trioleate is compatible with most non-polar and oil-phase ingredients including natural oils, synthetic esters, fatty alcohols, and hydrocarbon solvents. It should be tested for compatibility with high-polarity actives and aqueous phases, as it is insoluble in water. Standard formulation compatibility testing is recommended for novel blends.
