Abstract: The present invention is a hair treatment composition containing components (a) and (b): (a) a compound having 2 or 3 amino acid residues and represented by general Formula (1), or a salt thereof [in the formula, X denotes a divalent hydrocarbon group having 1 to 4 carbon atoms, which may be substituted with a hydroxy group, or a specific amino acid residue, Y denotes a specific amino acid residue or a divalent group represented by chemical Formula (2) (in the formula, —* denotes a direct bond bonding to an adjacent carbonyl group or oxygen atom), R denotes a hydrogen atom or a monovalent hydrocarbon group having 1 to 4 carbon atoms, which may be substituted with a hydroxy group, m and n denote 0 or 1, and when m and n are simultaneously 1, X is not an amino acid residue]; and (b) an aliphatic carboxylic acid having no greater than 8 carbon atoms or a salt thereof.

Abstract: Provided is an aqueous hair cosmetic composition containing (A) a tertiary amine type cationic surfactant, (B) an aromatic alcohol, (C) a branched fatty acid or salt thereof, and water, wherein Component (B) and Component (C) at a (B)/(C) weight ratio falls within a range of from 100/1 to 1/10. The aqueous hair cosmetic composition of the present invention can repair or prevent the hair damage and fatigue breakdown and give good flexibility and a supple touch to the hair during from wetting to even after drying.

Abstract: Provided is a hair cosmetic composition containing (A) an amidoamine (1) or an etheramine (2), or a salt thereof, (B) a branched fatty acid (3) or a salt thereof, (C) a silicone, and water: in the formula (1), R1 represents an aliphatic C11-23 hydrocarbon group, R2 represents H or a C1-4 alkyl group, and m stands for a number from 2 to 4; in the formula (2), R3 represents a C6-24 alkyl or alkenyl group, and R4 and R5 each represents a C1-6 alkyl group or a group -(AO)nH, in which A represents a C2-4 alkylene group and n stands for a number from 1 to 6; and in the formula (3), R6 represents a methyl or ethyl group, and p stands for a number from 3 to 36.

Abstract: A hair cosmetic is disclosed which comprises the following components (A), (B) and (C):(A) a cationic surfactant;(B) a fat and/or an oil; and(C) an alkyl saccharide surfactant represented by the following formula (1) :R.sup.1 --O--(R.sup.2 O).sub.m --G.sub.n (1)wherein the weight ratio of (A)/(C) is from 1 to 20. A hair cosmetic which further comprises fine particles of an average particle size of 100 .mu.m or below as the component (D) is also disclosed. The hair cosmetic of the present invention gives a good smoothness, a good elasticity and an oil-free feel to the hair without imparting any sticky feel or dry and loose feel thereto.
