PURPOSE:To enjoy a comfortable aroma by microcapsulating a perfume used in an atomizer. CONSTITUTION:The perfumes include ketones, aldehydes, esters, lactones, ethers, synthetic musks, and hydrocarbons, and to facilitate the capsulation, the perfumes can be mixed with other hydrophobic mediums to form core materials. The hydrophobic mediums include ketones such as benzyl benzoate and dioctyl phthalate, mineral oils such as kerosene, paraffin, and naphtene oil, aromatic hydrocarbons such as alkylated biphenyl and alkylated naphthalene, amides such as N,N-dimethylocytylamide, plants such as cottonseed oil, and others. The microcapsules include non-gradually releasing microcapsules in which the perfumes as the core materials are released only when the capsules are broken by a pressure such as friction, and gradually releasing microcapsules in which the perfumes are gradually released through porous wall films even in the state where the capsules are not broken. |
