Claim 1
Independent Claim
112 words
A shampoo composition comprising: (a) from about 0.01% to about 10% of a rigid silicone having a complex viscosity of at least 2×10 5 poise selected from the group consisting of filler reinforced polydimethyl siloxane gums, silicone resin reinforced silicone gums and mixtures thereof; (b) from about 10% to about 30% of a synthetic surfactant; (c) from about 0.1% to about 10% of a volatile solvent; (d) from about 0.2% to about 12% of about a 50% aqueous solution of an alkyl glyceryl sulfonate; and (e) the balance water, wherein a premix consisting of the rigid silicone and the alkyl glyceryl sulfonate is formed prior to mixing with the other shampoo components.
