Formula IngredientEmollient

Hydrogenated Lecithin

INCI: Hydrogenated Lecithin

Hydrogenated lecithin is a chemically modified form of lecithin, a naturally occurring phospholipid found in soybeans and egg yolks. The hydrogenation process makes it more stable and better suited for cosmetic formulations. It functions as both an emollient and emulsifier, and is widely used to create liposomes that can deliver active ingredients deeper into the skin.
