POROUS HOLLOW POLYMER PARTICLE, METHOD FOR PRODUCING POROUS HOLLOW POLYMER PARTICLE, FRAGRANCE MATERIAL-CARRYING POLYMER PARTICLE, AND METHOD FOR PRODUCING FRAGRANCE MATERIAL-CARRYING POLYMER PARTICLE

摘要

Disclosed is a porous hollow polymer particle which excels in extended release of fragrance material, light diffusion, liquid absorption, sensibility, solvent resistance and mechanical strength. Also disclosed are a fragrance material-carrying polymer particle which can stably carry fragrance material, while having excellent extended release of the fragrance material; a method for producing a porous hollow polymer particle; and a method for producing a fragrance material-carrying polymer particle. The porous hollow polymer particle has a plurality of pores in the internal portion of the particle, and the outer surface and the inner surface of the particle are coated with a polyvinyl alcohol.
