What does this ingredient do in an antiperspirant?
A copolymer of methyl vinyl ether and the monoethyl ester of maleic acid. INCI functions: film forming, antistatic and hair fixing.
Part of a system, not a label in isolation
It forms a thin continuous film on the skin and contributes to the structure of the formula. It does not reduce sweating.
In its amended assessment of PVM/MA copolymer and its salts and esters, the CIR concluded that these ingredients are safe for use in cosmetics (2011); the CIR summary table lists concentrations of up to 30% for Ethyl Ester of PVM/MA Copolymer.
It is generally used as a supporting polymer; an individual reaction to the finished product is possible.
Not the same as PVM/MA Copolymer or Butyl Ester of PVM/MA Copolymer: the CIR assessed them as one group, but they are different ingredients.
