Functions

Cleansing

Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.

Hair 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

Modern mild surfactant synthesized in the late 20th century by combining stearic acid with amino acid glutamate. Developed as a gentler alternative to traditional sulfate surfactants for sensitive skin applications.
