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.

Locks in moisture

Traditional Use

Developed in the late 20th century as a synthetic amino acid derivative. Created to improve skin barrier function and provide emollient properties in modern skincare formulations.
