1. A process for incorporating a perfume into a detergent product comprising the steps of:

  • combining a dispersed perfume with one or more non-ionic emulsifiers at a temperature sufficient to form a homogeneous non-aqueous liquid phase;

    heating an aqueous phase, consisting essentially of water, to a temperature substantially the same as the non-aqueous liquid phase;

    mixing the aqueous phase and non-aqueous phase under shear conditions such that an emulsion containing liquid crystal structures, which surround the dispersed perfume is formed;

    dispersing the structured emulsion into a detergent composition.
