Abstract
The invention concerns a process for incorporating a perfume into a detergent 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 detergent composition. The invention also concerns the detergent products thus obtained. The structured emulsion comprises 1-30% by weight of non-ionic emulsifiers, 1-50% by weight of a perfume and 20-98% by weight of an aqueous phase. The detergent product comprises at least 4% by weight of surfactant.
