PURPOSE:Solid perfume having improved shape retention, releasing perfume gradually at a controlled rate, obtained by dissolving a specific gelatinizing agent in a perfume solution under heating to give a gelatinizing solution, impregnating open-cell foam with the gelatinizing solution, cooling and gelatinizing it. CONSTITUTION:The open-cell space of open-cell foam (preferably one having 5-70 times expansion magnification and >=70% open-cell ratio) consisting of a base material such as polyolefin, polyurethane, synthetic or natural rubber, etc. is impregnated with a gelatinizing solution of perfume obtained by dissolving Gelol D [manufactured by Shinnippon Rika KK] in a perfume solution under heating, the gelatinizing solution of perfume is cooled and gelatinized, to give solid perfume wherein the open-cell space is impregnated with the gelatinized material of perfume. The gelatinizing solution is used with hydroxypropyl cellulose (in an amount 1-5 times as much as Gelol D), the prepared gelatinized material is completely transparent, and dispersion medium (perfume solution) contained in the gap of gel structure will not ooze out. |
