What Is Glyceryl oleate?

Glyceryl oleate, also called glyceryl monooleate, is a clear or light yellow liquid derived from olive oil, peanut oil, pecan oil, or teaseed oil.[1,2] It has a sweet odor and a fatty taste; it melts at around 77 degrees Fahrenheit. It does not dissolve in water but dissolves in oil.[3,4]

What Does Glyceryl oleate Do in Our products?

Glyceryl oleate can be used as an emollient to keep products blended together; it can also be a flavoring agent in food — often in baked goods or baking mixes, beverages, gum, and meat products.[5] In our products, however, glyceryl oleate is used for its most common purpose — to bind moisture to the skin. It is a common ingredient in sunscreen and hundreds of other cosmetic products.[6]

Why Puracy Uses Glyceryl oleate

We use glyceryl oleate in several of our products as a moisturizer. Several studies find that the ingredient does not irritate skin or act as a sensitizer; it produces minimal to moderate eye irritation.[11,12] The Cosmetic Ingredient Review has deemed the ingredient safe for use in cosmetics.[13] Whole Foods has deemed the ingredient acceptable in its body care and cleaning product quality standards.[14,15] Though glyceryl oleate is used topically in our products, the FDA has deemed it generally recognized as safe (GRAS) as a direct human food ingredient; the Food and Agriculture Organization of the United Nations and the World Health Organization has also deemed it safe as a flavoring agent.[16,17]

How Glyceryl oleate Is Made

Glyceryl oleate is the ester of glycerin and oleic acid. Glyceryl esters are esters that are primarily fatty acid mono- and diglycerides or triglycerides modified by reaction with other alcohols.[7] Glyceryl oleate is made by partially hydrolyzing tri- and diglycerides by esterification of glycerol with oleic acid or by glycerolysis of common fats and oils. The glycerolysis of fats and oils, a transesterification reaction, is a common commercial production method for monoglycerides.[8] The basic ingredients for commercially produced monoglycerides are partially or fully hydrogenated deodorized vegetable oils, glycerol, and sodium hydroxide as a catalyst.[9] Glycerin is typically a byproduct of the products of soap and fatty acids; oleic acid is usually obtained by hydrolyzing natural fats or pine sap derivatives. The fats can be vegetable or animal-derived, though we only use the vegetable-derived versions, which are commonly sourced from soybeans, cottonseed, corn, and canola.[10]
