BUTYL ACRYLATE/ETHYLHEXYL METHACRYLATE COPOLYMER.

Valuable / FILM FORMING, HAIR FIXING

A synthetic polymer that creates flexible, durable films on skin and hair surfaces through cross-linking mechanisms. This copolymer enhances product longevity and provides protective barrier properties while maintaining compatibility across all skin types.

film former hair fixative

Science

Forms a continuous, flexible film upon solvent evaporation that creates a protective barrier on skin surfaces, enhances cosmetic product durability, and provides structural support through polymer cross-linking on keratinous surfaces.

N/A

Key findings

  1. 01 Demonstrated safety for leave-on facial applications without sensitization or significant irritation in acrylates copolymer class assessment
  2. 02 No skin irritation or sensitization potential observed in human patch testing of related copolymer emulsions

Transparency

Not commonly dusted

Well-established film-forming polymer with clear safety profile and specific functional benefits


The Formula

Solubility
Both
Optimal pH 6 – 8
0 7 14

Stability

Anionic polymer requiring base neutralization for aqueous solubility; precipitates below pH 3.5; achieves optimal stability and clarity in neutral to slightly alkaline conditions

Conflicts

  • Strong acids (cause precipitation)
  • Cationic surfactants (form insoluble complexes)
  • High electrolyte concentrations (reduce film flexibility)

Safety

CIR Status
