Abstract

Abstract A hair cosmetic composition comprising: (A) 0.05% to 10% by weight of at least one quaternary ammonium salt having the formula: ##STR1## wherein R 1 is an alkenyl having 14 to 20 carbon atoms, R 2 is an alkyl or alkenyl having 14 to 20 carbon atoms, R 3 and R 4 are independently methyl, ethyl, a polyoxyethylene having an average polymerization degree of 1 to 5, or a polyoxypropylene having an average polymerization degree of 1 to 5, and X - is an anion, and having an iodine value of 35 to 100; and (B) 0.05% to 10% by weight of a phosphate having the formula: ##STR2## wherein R 5 is a linear alkyl having 1 to 22 carbon atoms, a hydroxyalkyl having 1 to 22 carbon atoms, an alkenyl having 2 to 22 carbon atoms, an alkylphenyl having 7 to 22 carbon atoms, or glyceryl, R 6 is hydrogen or methyl, R 7 is hydrogen, an alkali metal, a C 1 -C 20 alkyl-substituted ammonium, or a C 1 -C 20 hydroxyalkyl-substituted ammonium, R 8 is a group having the formula ##STR3## or R 7 , n is an integer of 0 to 100, and R 5 and R 6 are the same as defined above.
