STYRENE/ACRYLATES COPOLYMER

Last update on Jan 12, 2026

Styrene/acrylates copolymer is a synthetic polymer consisting of acrylates and styrene. It is added to cosmetic and skin care products for color or for its opaque properties. It forms a film and does not penetrate the skin because it has fairly large molecules. The chemical formula of Styrene/acrylates copolymer is C11H11O2.

What is STYRENE/ACRYLATES COPOLYMER used for?

Styrene Acrylates/Copolymer is used in a range of cosmetic and skin care products.
 

  • In decorative cosmetics, for its film-forming properties in nail polishes and eyeliners
  • In sunscreens, it is used to make water-resistant formulas

Origin

Styrene/Acrylates Copolymer is produced synthetically through emulsion or solution polymerization of styrene and acrylate monomers (such as butyl acrylate). The process involves controlled chain growth under specific conditions to yield a stable polymer dispersion or solid. Derived from petrochemical sources, it ensures consistent purity and performance for cosmetic applications.

Safety Profile

Styrene/Acrylates Copolymer is considered safe for cosmetic use per the CIR Expert Panel assessment of acrylates copolymers, with low absorption due to large molecular weight. It carries a low hazard rating from EWG, with minimal concerns for irritation or sensitization when formulated properly. Potential contamination with residual styrene (a possible carcinogen) is a noted issue, but levels are minimized in compliant grades. Patch testing is recommended; approved by EU COSING for film forming and opacifying functions.
