Polyvinyl Butyral

Polyvinyl Butyral is a synthetic polymer known for its film-forming and adhesive properties. In cosmetics, it helps to create a flexible, transparent film that can improve product wear, water resistance, and adhesion to skin or nails. It is commonly used in nail polishes and some makeup products.
