Abstract
Abstract A hair rinse composition comprising one or more quaternary ammonium salts, a silicone derivative and a polyethylene glycol is disclosed. The ammonium salts are represented by ##STR1## wherein one or two of the R's are certain higher alkyl or hydroxyalkyl groups and the rest are certain lower alkyl, lower hydroxylalkyl, benzyl or polyoxyethylene groups, and X is a halogen atom or alkylsulfuric group. The hair rinse composition according to this invention has superior rinsing effects, i.e., effectiveness to impart adequate softness, smoothness and antistatic property to hair.

A hair rinse composition comsisting essentially of the following three components (A), (B) and (C): (A) 0.1 to 20 percent by weight of one or more quaternary ammonium salts represented by the general formula (I): ##STR9## where two of R 1 , R 2 , R 3 and R 4 are each a long chain alkyl group having 8 to 20 carbon atoms and the rest of them are each an alkyl group having 1 to 3 carbon atoms, a benzyl group or a polyoxyethylene group consisting of a total of not more than 10 molar monomer units; and X is a halogen atom; (B) 0.1 to 20 percent by weight of a dimethylpolysiloxane represented by the following formula: (CH.sub.3).sub.3 SiO[(CH.sub.3).sub.2 SiO]x.sub.1 Si(CH.sub.3).sub.3 (where, x 1 is an integer of 3 to 650); and (C) 0.1 to 30 percent by weight of polyethylene glycol having an average molecular weight of 200 to 100,000.
