Abstract
Abstract A shampoo composition comprising from 10 to 60% by weight of (a) one or more anionic surfactants, from 1 to 15% by weight of (b) one or more nonionic surfactants, from 0.1 to 25% by weight of (c) a silicone component, selected from polydiorganosiloxanes and cyclodiorganosiloxanes wherein substantially all organic substituents are lower alkyl groups, from 6 to 18% by weight of (d) a salt of saccharin and from 20 to 70% by weight of (e) water. The saccharin salt is preferably a sodium salt, which acts as optical index adjusting agent to provide a clear shampoo and also renders the foam creamier.
