Functions
Viscosity Controlling
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.

Traditional Use
Developed in the late 20th century as a synthetic film-forming polymer for cosmetics. Used in modern skincare and cosmetic formulations to create water-resistant coatings and improve product durability on skin.
