Abstract
A fragrance-containing microparticle of water-insoluble polymeric material, the polymer having a glass transition temperature of from 0° C. to 50° C. and a zeta potential lying within the ranges −40 mV to −5 mV and +5 mV to +45 mV. The microparticles have enhanced substantivity to hair, resulting in a longer-lasting fragrance.
