What it is
Glyceryl Citrate/Lactate/Linoleate/Oleate is a multifunctional ester of glycerin with a blend of citric, lactic, linoleic, and oleic acids. The fatty-acid portions provide emollience while the polar acid components help stabilize oil-in-water emulsions, so it can act as a gentle co-emulsifier. In sunscreens it supports a smooth texture and even spreading of the formula.
Safety & warnings
It is generally well tolerated and is often chosen as a milder emulsifier option; it is not a recognized fragrance allergen. Because it contains oleic and linoleic acid esters, very acne-prone users may wish to note how rich formulas containing it perform on their skin.
Origin & sourcing
Synthetic ester blend made by reacting glycerin with citric, lactic, linoleic, and oleic acids; the fatty acids are commonly of vegetable origin.
