Functions
Hair 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.
Conditions Hair
Cleansing Surfactant
Emulsifier
Lifts away dirt and oil
Softens and detangles hair
Mixes oil and water
Traditional Use
A hybrid modern ingredient combining lanolin (sheep's wool fat, used historically for skin conditioning) with synthetic polyols developed in the 20th century to create stable emulsifiers.
