OH DAISEY INGREDIENT LIBRARY
Ethylene/Propylene/Styrene Copolymer
CIR concluded that styrene and vinyl-type styrene copolymers are safe as used in cosmetics. The polymer has low expected skin absorption, although manufacturing controls should limit residual monomers.
OH DAISEY VERDICT
Approved
Evidence level: Strong
Why Oh Daisey rates it this way
CIR concluded that styrene and vinyl-type styrene copolymers are safe as used in cosmetics. The polymer has low expected skin absorption, although manufacturing controls should limit residual monomers.
