Patent ID: 8293220

Claim:
A hair cosmetic composition comprising the following ingredients (A), (B), (C), and (D): (A) a di-long-chain cationic surfactant in an amount of 0.1 to 5 mass % with respect to the entirety of the hair cosmetic composition, said di-long-chain cationic surfactant being represented by formula (1): wherein each of R a COs, which may be identical to or different from each other, represents an aliphatic acyl group having 10 to 22 carbon atoms and 0 to 3 double bonds; p is an integer of 1 to 3; and X represents a halogen atom, metosulfate, or metophosphate; (B) an ethylene oxide adduct of 1,2-alkanediol and/or an N-acyl-N-methylmonoethanolamide in an amount of 0.5 to 20 mass % with respect to the entirety of the hair cosmetic composition, said ethylene oxide adduct of 1,2-alkanediol being represented by formula (2): wherein R b represents a hydrocarbon group having 8 to 20 carbon atoms and 0 to 2 double bonds; each of m and n, which represent amount by mol of added ethylene oxide, is an integer of 0 to 2; and the average of m+n is greater than 0 and smaller than 2; and said N-acyl-N-methylmonoethanolamide being represented by formula (3): wherein R c represents a hydrocarbon group having 9 to 21 carbon atoms and 0 to 2 double bonds; (C) a hydrophobicized alkyl cellulose in an amount of 0.01 to 1 mass% with respect to the entirety of the hair cosmetic composition; or a cationic polymer in an amount of 0.03 to 2 mass % with respect to the entirety of the hair cosmetic composition; or the hydrophobicized alkyl cellulose and the cationic polymer in a total amount of 0.03 to 1.5 mass % with respect to the entirety of the hair cosmetic composition, said hydrophobicized alkyl cellulose being represented by formula (4): wherein R represents a bonding group R 1 -R 2 ; a plurality of R 1 s, which may be identical to or different from one another, represent at least one group selected from among —[CH 2 CH(CH 3 )O] r —, —[CH 2 CH 2 O] r —, and —[CH 2 CH(OH)CH 2 O] r —(wherein r is an integer of 0 to 4); R 2 represents at least one group selected from among a C12 to C28 hydrocarbon group, a hydrogen atom, and a C1 to C4 alkyl group, with at least one R 2 being a C12 to C28 hydrocarbon group; A represents a group —(CH 2 ) t —(wherein t is an integer of 1 to 3); and s is a number of 100 to 10,000; and said cationic polymer being represented by formula (5): wherein Y represents a halogen atom, and u represents the number of bonded quaternary ammonium unit(s); and (D) water.
