HAIR COSMETIC COMPOSITION

摘要

A hair cosmetic composition comprising the following components (A), (B) and water, having a pH of 6 or less, and the component (B) being dispersed in a water phase:;(A) an oxyalkylene polymer represented by formula -(AO)n— wherein A represents a C2-6 alkylene group and n represents a number of 50 to 30,000, provided that n pieces of AO comprise at least two alkyleneoxy groups, which are arranged through either random polymerization or block polymerization; and;(B) a polymer comprising a constitutional unit represented by the following formula (b1) and a constitutional unit represented by the following formula (b2), having a weight average molecular weight of 5,000 to 1,000,000, and having an acid value of 5 to 400:;—(CH2CR1COOH)—  (b1);—(CH2CR2COOR3)—  (b2);wherein R1 and R2 represent H or CH3, and R3 represents a C1-30 hydrocarbon group.

1: A hair cosmetic composition comprising components (A), (B) and water, having a pH at 25° C. of 6 or less, and component (B) being dispersed in a water phase of the hair cosmetic composition:
(A) an oxyalkylene polymer represented by formula (a1):
-(AO)n—  (a1) wherein A represents an alkylene group having 2 to 6 carbon atoms and n represents a number of 50 or more and 30,000 or less, provided that n pieces of AO comprise at least two alkyleneoxy groups, which are arranged either randomly or in blocks; and (B) a polymer comprising a constitutional unit represented by formula (b1) and a constitutional unit represented by formula (b2), having a weight average molecular weight of 5,000 or more and 1,000,000 or less, and having an acid value of 5 or more and 400 or less:
—(CH2CR1COOH)—  (b1)—(CH2CR2COOR3)—  (b2) wherein R1 and R2 represent a hydrogen atom or a methyl group and R3 represents a hydrocarbon group having 1 or more and 30 or less carbon atoms.
