Provided is a hair cleansing composition containing (A) an amphipathic amide lipid, (B) an anionic surfactant and (C) an organic or inorganic acid, or a salt thereof, and having a pH of from 1 to 4.5 when diluted with water to 20 times the weight. The hair cleansing composition of the present invention has advantages including protecting hair from physical or chemical stimulation and preventing split ends or breakage of hair without impairing the cleansing ability and feeling upon use, imparting hair with a pleasant feeling to the touch and moisture retention properties such as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses, and has excellent stability.

Hair cleansing composition

Provided is a hair cosmetic composition containing (A) an amphipathic amide lipid, (B) a cationic surfactant or a tertiary amine type compound represented by the following formula (N): wherein, A represents a hydrogen atom or a linear or branched, saturated or unsaturated amide, (N-hydrocarbon)carbamoyl, acyloxy or hydrocarbonoxy group each having 12 to 24 carbon atoms in total, B represents a linear or branched, saturated or unsaturated Chydrocarbon group, and Zand Zeach represents a Calkyl group; or a salt of the compound, and (C) a silicone; and having a pH at 25&#xb0; C. of from 1 to 4.5 when diluted with water to 20 times the weight of the composition.

Hair cosmetic composition

Provided is a hair cosmetic composition containing (A) from 0.001 to 10 wt. % of an amphipathic amide lipid, and (B): from 0.05 to 10 wt. % of a dialkyl ether or ethylene glycol dialkyl ether with an alkyl group having from 18 to 22 carbon atoms, or an ethylene glycol monofatty acid ester, ethylene glycol difatty acid ester, fatty acid monoethanolamide or acylated &#x3b2;-alanine with an acyl group having from 18 to 22 carbon atoms. The hair cosmetic composition of the present invention for example, protects the hair from physical or chemical stimulation, prevents appearance of split ends and broken hair, imparts natural smoothness, moist feeling, resilience and strength, and moisture retention property to the hair after treatment (shampooing), and at the same time has excellent storage stability.

Provided is a hair cleansing composition comprising (A) an amphipathic amide lipid, (B) an anionic surfactant and (C) a silicone. The hair cleansing composition of the present invention has advantages such as protecting hair from physical or chemical stimulation and preventing split ends or hair breakage without impairing its cleansing ability and feeling upon use, and moreover, gives to hair after shampooing a pleasant feeling to the touch and moisture retention properties such as natural smoothness, moist feeling, and suppleness which healthy hair inherently possesses, and has excellent stability.

The present invention relates to a hair shampoo composition containing (A) an amphipathic amide lipid, and (B), from 5 to 30 wt. % of sulfate surfactants which are each represented by the formula: R&#x2014;O&#x2014;(CHO)&#x2014;SOM (wherein, R represents a Calkyl or alkenyl group, a stands for 0 or a positive integer, and M represents an alkali metal, alkaline earth metal, or the like); are made of from 30 to 45 wt. % of a sulfate exhibiting a=0, from 18 to 27 wt. % of another sulfate exhibiting a=1, from 10 to 20 wt. % of a further sulfate exhibiting a=2, and the balance of further sulfates exhibiting a=3 or greater; and contain the sulfates exhibiting a=0 to 2 in an amount of 70 wt. % or greater based on the total sulfates. The hair shampoo composition of the present invention is able to for example have good foaming property, provide foam with good lubrication upon shampooing, have smooth feel upon rinsing, impart a pleasant feel such as gloss, manageability, resilience and strength to the hair after shampooing, and protect the hair from physical or chemical stimulation to make it resistant to damage.
