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.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
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
A modern silicone-based emulsifier developed in the late 20th century to improve texture and spreadability in cosmetic formulations. Created to replace traditional waxes and oils with more stable, lightweight alternatives.
