More Information
Summary:A composition which comprises (A) a plurality of cross-linked polymer particles, said polymer being the polymerization product of at least two monomer units selected from the group consisting of monoalkenyl aromatic compounds, alkyl esters derived from a saturated alcohol and acrylic or methacrylic acid, and vinyl esters of an aliphatic carboxylic acid; and said cross-line polymer particles being loaded with (B) an active ingredient, the weight ratio of the active ingredient (B) to the polymer particles (A) being from 0.05 to 50:1, is useful to release the active ingredient over an extended period of time while controlling sebum on skin and hair.
