Abstract

The present invention provides an effective conditioning shampoo composition which is free of conditioning amounts of silicone conditioning agents. It comprises: A) about 5% to about 40% of a detersive surfactant mixture of an anionic detergent and an amphoteric surfactant, the weight ratio of the anionic detergent to the amphoteric surfactant being in the range of about 10:1 to 0.8:1; B) about 0.05% to about 6% of a conditioning agent selected from the group consisting of 0.05% to 5% of a complex of essentially equimolar amounts of a C₈ -C₁₈ (EtO)_1-10 carboxylic acid, and a C₈ -C₁₈ alkyl (EtO)_0-10 dimethyl amine; 0.05% to 1.0% of a polyquaternary compound selected from the group consisting of a quaternized cellulosic polymer and a mixture of the quaternized cellulosic polymer with a non-cellulosic quaternary conditioning polymer; and mixtures of the foregoing; C) 0.1% to 1% of a static control mixture of a quaternary ammonium salt having the formula R₉, R₁₀, R₁₁, R₁₂ N⁺ X^- wherein R₉ is a C_l4 -C₁₈ alkyl, R₁₀ and R₁₁ are each a C₁ -C₄ alkyl, R₁₂ is C₁ -C₄ alkyl or benzyl and X^- is a salt forming cation selected from the group consisting of chloride, bromide, methosulfate and ethosulfate; and a di-quaternary ammonium salt having the formula (R₁₃)₂ R₁₄ R₁₅ N⁺ X^- wherein R₁₃ is a C₁₄ -C₁₈ alkyl or alkylene group and R₁₄ and R₁₅ are each a C₁ -C₄ alkyl group or a (CH₂ CH₂ O)_n H group with at least one of R₁₄ and R₁₅ being a (CH₂ CH₂ O)_n H group, n is an integer from 2 to 20 and X is a cation as set forth above, the weight ratio of the monoalkyl quaternary salt to dialkyl quaternary salt being from about 1:4 to 4:1; and D) an aqueous medium. These compositions exhibit enhanced antistatic properties as compared to the same compositions containing either the monoalkyl quaternary salt or the dialkyl quaternary salt as the sole antistatic ingredient.
