A first problem is to provide a novel technique for forming hyaluronan into particles. Further, a second problem is to provide a novel technique suitable for production of a composite particle containing an anionic polymer and a peptide. Means for solving the first problem is a composite particle containing an anionic polymer, and a cationic polymer (except for chitosan) having a degree of cationization of 0.2 or more. Means for solving the second problem is to mix an anionic polymer and a peptide in an aqueous solvent having a pH of 5 or less.

FRAGRANCE-CONTAINING MICROPARTICLES

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.
