Soy Phospholipids
What is Soy Phospholipids?
Soy Phospholipids are phospholipids derived from soybeans, primarily consisting of phosphatidylcholine, phosphatidylethanolamine, and other glycerophospholipids. They are obtained through the partial hydrolysis of soy lecithin and function as skin-identical emollients and emulsifiers in skincare formulations. These ingredients help restore the skin's natural lipid barrier, enhance moisture retention, and improve the delivery of active ingredients.
Roles in Formulation
This ingredient serves the following purposes in cosmetic formulations:
Emollient

Skin protecting
Forms a barrier to protect skin from external irritants.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
