Functions
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Viscosity Controlling
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Smoothing
Creates Protective Barrier
Controls Viscosity
Anti-Aging Benefits
Antioxidant Protection
Reduces Inflammation
Creates protective layer
Controls product thickness
Traditional Use
A synthetic polymer developed for cosmetic use to provide film-forming and conditioning properties. Created in modern cosmetic chemistry as an alternative to natural resins for improved product stability and performance.
