Functions
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
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.
Creates Protective Barrier
Traditional Use
A synthetic conditioning agent created in the latter half of the 20th century for cosmetic formulations. Used primarily in haircare products for smoothing and anti-static properties.
