Abstract:
Provided are compositions and methods that are useful for hair care compositions. The compositions comprise polyurethane microparticles coated with zinc salt particles, wherein the ratio of zinc salt to polyurethane is in a range of from 1:99 to 3:7, and the polyurethane microparticles have an average particle size of less than 100 microns. Also provided are methods of preparation of such compositions.
