Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks in moisture
Traditional Use
Phosphatidylcholine is a naturally occurring phospholipid found in egg yolks and soy, used traditionally in Ayurveda. The hydrogenated version was developed in the 20th century as a biocompatible emulsifier for modern skincare and liposomal delivery systems.
