Abstract
Abstract A hair rinse composition comprising as indispensable components (A) 0.1 to 10% by weight of at least one quaternary ammonium salt having the formula (I): ##STR1## wherein R 1 , R 2 , R 3 and R 4 each is alkyl, hydroxyalkyl or benzyl, with the proviso that one or two of R 1 , R 2 , R 3 and R 4 is alkyl or hydroxyalkyl having 8 to 20 carbon atoms and the remainder of R 1 , R 2 , R 3 and R 4 are alkyl or hydroxyalkyl having 1 to 3 carbon atoms, or benzyl, and X is an anion, And (B) 0.1 to 10% by weight of a secondary alcohol or ethoxylate thereof in which the average mole number of added ethylene oxide units is zero to 7 and the alkyl group has 8 to 20 carbon atoms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
194 words
A liquid hair rinse composition consisting essentially of (a) from 0.1 to 10 percent by weight of one or a mixture of quaternary ammonium salts having the formula ##STR5## wherein each of R 1 , R 2 , R 3 and R 4 is alkyl, hydroxyalkyl or benzyl, with the proviso that one or two of R 1 , R 2 , R 3 and R 4 is alkyl having 8 to 20 carbon atoms or hydroxyalkyl having 8 to 20 carbon atoms and the remainder of R 1 , R 2 , R 3 and R 4 are alkyl having one to 3 carbon atoms, hydroxyalkyl having one to 3 carbon atoms or benzyl, and X is halide, methylsulfate or ethyl sulfate, (b) from 0.1 to 10 percent by weight of a synthetic secondary alcohol prepared by oxidizing normal paraffin or an ethoxylate thereof, said alcohol having the formula ##STR6## wherein n is a number from zero to 7 and ##STR7## is alkyl having 12 to 18 carbon atoms, and (c) an amount of a water-miscible organic solvent effective to dissolve components (a) and (b), and (d) the balance consists essentially of water.
