Common Name(s): 2-hydroxypropyl acrylate,linear acrylate polymer,rheology/film-forming modifier

CAS Number: N/a

DESCRIPTION

What It Does: Provides film formation for hair styling, long-wear make-up, and emulsion stabilisation through controlled polymer architecture.

Why It's Used: Synthetic acrylate polymers deliver precisely engineered rheological and film properties unavailable from natural biopolymers — molecular weight, crosslink density, and monomer ratio precisely control the performance output.

How It Works: Linear copolymer film formation above tg on drying — hard monomers (mma, styrene) set tg; soft monomers (ea, ba) reduce tg. film flexibility controlled by monomer ratio.
