STABILIZED CLATHRATE COMPOUND AND COSMETIC CONTAINING SAME

摘要

PURPOSE:To obtain a clathrate compound capable of controlling the volatility of perfumery and stably keeping the perfumery in any storage state, by coating a clathrate compound of a perfumery and cyclodextrin (CD) with an oil. CONSTITUTION:1pt.(wt.) of CD is thoroughly kneaded with 0.5-5pts. of water and the produced paste is further kneaded together with a perfumery to effect the inclusion of the perfumery. The obtained paste is dried and finely pulverized with a crusher. The resultant CD clathrate compound is added to a liquid oil (or heated oil which is solid at normal temperature) and dispersed by mixing to effect the coating of the oil to the clathrate compound. The oil is preferably a nonpolar liquid (e.g. liquid paraffin, squalane, etc.) and the weight ratio of the oil to the clathrate compound is 10:1-1:100. The coated CD-clathrate compound is preferably added at an amount of about 1-10% based on the whole cosmetic.
