Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
A butylated polyvinylpyrrolidone copolymer used in hair sprays and styling products. CIR considers PVP-family polymers safe at typical cosmetic concentrations but residual monomer is a watchpoint.
Skin benefits
- Provides strong hair-styling film and hold
- Improves humidity resistance versus plain PVP
- Functions as binder and viscosity controller
Known concerns
- May leave buildup on hair with repeated use
- Residual monomer (vinylpyrrolidone) is theoretically carcinogenic if present
- Limited dermal absorption data for the butylated variant
- Can cause irritation in sensitive individuals when aerosolized
