PURPOSE:A cosmetic for hair that contains a quanternary ammonium salt containing 16-18C alkyl groups, a quaternary ammonium salt containing 20-22C alkyl groups and polyoxyethylene palm fatty acid monoethanolamide phosphate ester as essential ingredients. CONSTITUTION:The objective cosmetic for hair contains 0.1-3wt% of a compound of formulaI(R1 is 16-18C alkyl; R2-R4 are 1-3C alkyl, hydroxyalkyl; X is halogen, alkylsulfate), 0.1-3wt% of a compound of formula II (R5 is 20-22C alkyl; R6-R8 are the same as R2-R4) are 0.1-4.0wt% of a compound of formula III (R is 9-17C palm fatty acid residue; A is RCONHCH2CH2O(CH2CH2O)n or M; M is H, Na, triethanolamine; m is 3-6), where the weight ratio ofI/II is 1/3- 3/1. The resultant cosmetic gives hair high smoothness and softness and is used in either rinsing type or nonrinsing type. |
