Description
Glyceryl Trioleate (CAS 122-32-7) is a triglyceride composed of glycerol fully esterified with three oleic acid chains, commercially known under names including Triolein, Olein, and Raoline, and abbreviated as 18:1TG. It carries no assigned E-code and is classified under HS code 29161500.
In personal care formulations, it functions as an emollient by integrating into the lipid barrier of skin, reducing transepidermal water loss rather than simply coating the surface. In food and lubricant applications, its oleic acid backbone provides thermal stability and low-temperature fluidity, making it effective as a flavorant carrier and as a base fluid in metalworking lubricants where boundary lubrication is required.
Glyceryl Trioleate is available in technical and cosmetic grades, with select batches meeting FCC or Ph.Eur. specifications for food and pharmaceutical use. The substance is registered under REACH and supplied in drum and IBC formats. Buyers should confirm grade suitability against their regional regulatory requirements prior to formulation.
