摘要:
Disclosed is a method of preparing a product composition comprising steps of: Preparing a mixture composition comprising a surfactant and a high melting point fatty compound and benefit agent; Separately preparing an aqueous base composition comprising an aqueous carrier and water soluble polymer, wherein the base composition is substantially free of a detersive surfactant selected from anionic surfactants, zwitterionic surfactant, amphoteric surfactant, and combinations thereof; Mixing the mixture composition and the aqueous base composition to form a discrete particle of the mixture composition dispersed in the aqueous base composition. Alternatively, the method comprises steps of preparing a discrete particle of the mixture composition; and mixing it with the aqueous composition. The methods of the present invention provide a product composition with at least one the followings: more flexibility in the product composition rheology; improved stability in the product composition; improved deposition of benefit agents; and improved visual/aesthetic appearance.
