Abstract
An antidandruff shampoo composition includes a suspension composition for particulate matter to achieve an unexpected reduction in shampoo separation while maintaining acceptable shampoo viscosities and foaming levels. The suspension composition includes a suspending alkanolamide and/or a wax ester in conjunction with an ethylene-maleic anhydride resin or a polyacrylic acid resin to yield anionic surfactant-based antidandruff shampoos or improved stability and aesthetics.
