ACRYLATES/DIETHYLAMINOETHYL METHACRYLATE/ETHYLHEXYL ACRYLATE COPOLYMER.

Valuable CAS 67874-96-8 / FILM FORMING

This latex-based film-forming polymer creates a flexible, adhesive network on skin, providing immediate tightening and smoothing of micro-relief. It is highly valued for imparting long-wear properties and water resistance to cosmetic formulations.

Science

On skin, it forms a continuous, cross-linked film that physically contracts upon drying, leading to an immediate tightening and smoothing effect. This robust network also provides water resistance and structural integrity on keratinous surfaces.

Key findings

  1. 01 Clinical studies demonstrate that formulations containing 2-10% of this copolymer visibly tighten skin, smooth wrinkles, and reduce under-eye bags through film-forming contraction.
  2. 02 In hair applications, a 50% solution (as part of a latex system) significantly improved humidity resistance and curl retention by forming a cross-linked network film.
