About
A polymer of butyl acrylate (CAS 9003-49-0) used as a binder and film former. The polymer itself is well tolerated; residual butyl acrylate monomer (a documented sensitizer) is the primary EU regulatory concern.
Function
Skin benefits
- Effective binding and film-forming
- Flexible, soft-touch coatings
- Compatible with solvent and aqueous systems
- High-MW polymer with limited skin penetration
Known concerns
- Residual butyl acrylate is a known skin sensitizer
- EU residual monomer limits apply
- Microplastic environmental persistence
- Ozone-depleting solvent restriction reference (manufacturing-context)
