Common Name(s): Acetoacetoxyethoxy methacrylate,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.

SCIENTIFIC NOTE

Eu regulation 2023/2055 restricts synthetic polymer microplastics — formulators must verify their specific polymer molecular architecture meets the non-microplastic definition (soluble, biodegradable, or not forming solid particles) to ensure continued use.
