The invention concerns a process for incorporating a perfume into a personal product, wherein the perfume is first combined with one or more non-ionic emulsifiers and an aqueous phase to form a structured emulsion containing liquid crystal structures, which surround the dispersed perfume, and thereafter this structured emulsion is dispersed into a personal product base. The invention also concerns the personal products thus obtained and the structured emulsions used in the process. The structured emulsions comprise 1-30 % by weight of one or more non-ionic emulsifiers, 1-50% by weight of a perfume and 20-98% by weight of an aqueous phase. Preferably low shear mixing is used in preparing the emulsions.
A process for preparing structured emulsions containing liquid crystal structures, and comprising an aqueous phase and a non-aqueous phase containing non-ionic emulsifiers and optional structuring aids, which comprises:
