What is vinyl caprolactam VP dimethylaminoethyl methacrylate copolymer?
INCI: Vinyl Caprolactam/VP/Dimethylaminoethyl Methacrylate Copolymer. SDS Link > Gaffix™ vc-713 polymer (sold as copolymer vc-713 in Europe) is a terpolymer of vinyl caprolactam/vinylpyrrolidone/dimethylaminoethyl methacrylate developed for hair fixative and styling formulations.
What is amino methacrylate copolymer?
DEFINITION Basic Methacrylate Copolymer is a cationic copolymer comprised of the monomers dimethylaminoethyl methacrylate, butyl methacrylate and methyl methacrylate in the molar ratio of 1:2:1. The copolymer is manufactured by a controlled polymerization process using a free radical donor initiation system.
Are acrylates safe?
Although the monomers may be toxic, the levels that would be found in cosmetic formulations are not considered to present a safety risk. Accordingly, these Acrylate Copolymers are considered safe for use in cosmetic formulations when formulated to avoid irritation.
What is ammonium methacrylate?
Styrene/Acrylates/Ammonium Methacrylate Copolymer is a polymer of styrene, ammoniummethacrylate and a monomer consisting of acrylic acid, methacrylic acid or one of their simple esters.
Is acrylate copolymer toxic?
Is ethyl methacrylate toxic?

What is styrene acrylates ammonium methacrylate copolymer?
What is Ammonio methacrylate copolymer type B?
Ammonio methacrylate copolymer type B (Eudragit® RS) is a polycationic polymer composed of methyl methacrylate and ethyl acrylate units, among which 4.5 to 7.0% methacrylic acid esters with quaternary ammonium groups are to be found [6].
Are acrylates carcinogenic?
* Ethyl Acrylate is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, NTP, DEP, IARC, NFPA and EPA. * This chemical is on the Special Health Hazard Substance List because it is a CARCINOGEN, FLAMMABLE and REACTIVE.
Is ethyl methacrylate a carcinogen?
Is styrene copolymer safe for skin?
HEALTH CONCERNS: Styrene acrylates copolymer is considered safe because there is a low likelihood of absorption of the full compound. However, contamination with the possible carcinogen styrene is a concern.
