Claim 2
Dependent Claim
62 words
A shampoo composition comprising: a) 5% to 70% by weight of a synthetic surfactant; b) from 0.01% to 10% by weight of a dispersed, insoluble nonvolatile silicone; c) from 0.5% to 5% by weight of a long chain (C₁₆-C₂₂) acyl derivative or a long chain (C₁₆-C₂₂) amine oxide; d) from 0.8% to 4% by weight of a pyridinethione salt; and e) water.
