Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A film-forming copolymer of n-butyl acrylate and amino methacrylates (CAS 67892-79-9). The diethylaminoethyl methacrylate component adds cationic conditioning; safety lives at the residual monomer level rather than in the polymer.
Function
Skin benefits
- Long-wear film-forming performance
- Cationic conditioning character from amino methacrylates
- Improves substantivity to keratin
- Suitable for both leave-on and rinse-off
Known concerns
- Residual n-butyl acrylate is a known sensitizer
- Diethylaminoethyl methacrylate residuals could form nitrosamines
- Microplastic environmental persistence
- Some EU residual-monomer scrutiny
