Abstract
PROCESS FOR PREPARING A W / O TYPE COSMETIC COMPOSITION The present invention relates to a process for preparing a W / O type cosmetic composition, comprising a continuous fatty phase and a plurality of dispersed aqueous phases, comprising the steps of: (1) preparing a (a) fluid fatty phase by mixing (a-1) at least one oil, (a-2) at least one crystallizable wax which has been melted and (a-3) at least one optional ingredient for the (a) fatty phase; (2) preparing a (b) fluid aqueous phase by mixing (b-1) water and (b-2) at least one optional ingredient for the (b) aqueous phase;(3) mixing the (a) fluid fatty phase with the (b) fluid aqueous phase at a temperature at which the (a-2) crystallizable wax is not crystallized to obtain a mixture of the (a) fatty phase and the (b) aqueous phase and (4) cooling the mixture obtained by step (3) to prepare the W / O type cosmetic composition, wherein the mixture of the (a) fluid fatty phase and the (b) fluid aqueous phase obtained by step (3) is subjected to shear stress during step (4), at least, at a temperature at which crystallization of the (a-2) crystallizable wax begins. The W / O type cosmetic composition prepared by the method according to the present invention is soft even if the composition includes a relatively large amount of wax and can provide a comfortable feeling during use.
