Common Name(s): Polyvinyl chloride,synthetic polymer,cosmetic film-former or rheology modifier
CAS Number: N/a
DESCRIPTION
What It Does: Provides polymer-based film formation, thickening, or texture modification with properties determined by the backbone chemistry, molecular weight, and functional group architecture.
Why It's Used: Synthetic polymers deliver precisely controlled performance through molecular engineering โ mw, backbone rigidity, and functional groups provide reproducible application outcomes unavailable from natural biopolymers.
How It Works: Pva film forms by chain entanglement above tg on solvent evaporation. vinyl alcohol groups provide h-bonding to nail keratin for adhesion; degree of hydrolysis controls water sensitivity.
