Hair cosmetic composition

摘要

A hair cosmetic composition comprising the following components (A) and (B) and having a pH of 6 or less: (A) an oxyalkylene polymer represented by the following general formula (a1): -(AO)n— (a1) wherein A represents an alkylene group having 2 to 6 carbon atoms and n represents a number from 50 to 30,000, provided that n number of AOs consist of at least two alkyleneoxy groups and are arranged through either random polymerization or block polymerization; and (B) a polymer containing a component unit represented by the following general formula (b1) and a component unit represented by the following general formula (b2) in a mass ratio (b1)/(b2) of 50/50 to 100/0: —(CH2CR1COOH)— (b1) —(CH2CR2COOR3)— (b2) wherein R1 and R2 represent H or CH3 and R3 represents a C2-20 hydrocarbon group.

1. A hair cosmetic composition, comprising:
(A) an oxyalkylene polymer represented by formula (a1):
-(AO)n—  (a1)wherein each A independently represents an alkylene group having 2 to 6 carbon atoms, n represents a number from 50 to 30,000, and at least two different AO groups are present in the oxyalkylene polymer and are arranged randomly or in blocks; and
(B) a polymer comprising a component unit represented by formula (b1) and a component unit represented by formula (b2) in a mass ratio (b1)/(b2) in a range of from 50/50 to 100/0:
—(CH2CR1COOH)—  (b1)—(CH2CR2COOR3)—  (b2)wherein each of R1 and R2 independently represents a hydrogen atom or a methyl group, and R3 represents a hydrocarbon group having from 2 to 20 carbon atoms;
wherein: a mass ratio of the oxyalkylene polymer (A) to the polymer (B) ((A)/(B)) is in a range of from 30/70 to 70/30; and the composition has a pH of 6 or less.
