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 C8C18 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 R¿9? is a C14-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 diquaternary ammonium salt having the formula (R¿13?)2R14R15N?+X-¿ wherein R¿13? is a C14-C18 alkyl or alkylene group and R14 and R15 are each a C1-C4 alkyl group or a (CH2CH20)nH group with at least one of R14 and R15 being a (CH2CH20)nH 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. |
