Glyceryl Citrate/Lactate/Linoleate/Oleate

What is Glyceryl Citrate/Lactate/Linoleate/Oleate?

Glyceryl Citrate/Lactate/Linoleate/Oleate is a multifunctional ingredient composed of partial esters formed by reacting glycerin with citric acid, lactic acid, linoleic acid, and oleic acid. Linoleic and oleic acids are unsaturated fatty acids typically sourced from plant oils like sunflower or olive. This pale yellow, viscous liquid arises through controlled esterification processes, yielding a product suited for anhydrous cosmetic formulations such as lip balms, solid cleansers, and deodorants. It acts as an emollient by depositing a thin lipid layer that mimics the skin's natural barrier, enhancing softness and flexibility. As an emulsifying agent, it reduces surface tension between oils, promoting uniform blending and preventing phase separation for smoother textures in oil-rich products.
