Provided is a rinse-off-type hair cosmetic composition used by being applied to hair and then washed away, the hair cosmetic composition comprising: the ingredients (A) to (C) below, and water, wherein a molar ratio of the ingredient. (B) to the ingredient (A), (B)/(A), is less than 3, and a mass ratio of the ingredient (C) to the ingredient (A), (C)/(A), is less than 1: 

Hair cosmetic

An aqueous hair cleansing agent containing the following components (A), (B) and (C) and water:

Aqueous hair cleansing agent

A hair cleansing composition contains (a), (b), and (c). Component (a), as particles having mean particle size of 0.5-50 &#x3bc;m, is a polyalkyleneimine derivative or a salt thereof, having weight average molecular weight of 3,300-50,000, with at least one of R&#x2014;CO&#x2014;, R&#x2014;(CH)&#x2014;CHX&#x2014;CH&#x2014;, and R&#x2014;NH&#x2014;CO&#x2014; bonded to 40 mol % or more of the N atoms of the polyalkyleneimine. In (a), Rrepresents H, alkyl, alkenyl, or the like; Rrepresents H, alkyl, alkoxy, alkenyl, or the like; n is 0 or 1; X represents H or OH; Rrepresents H, alkyl, or alkenyl; at least one of Rto Rhas 13 or more carbon atoms, and the entirety of Rto Rhas an average number of carbon atoms of 9 or more and a linear group content of 30 mol % or more. Component (b) is an anionic surfactant. Component (c) is a water-soluble cationic polymer.

Hair cleansing composition

Provided are a rinse-off, non-dyeing type hair cosmetic composition containing (a) a polycarboxylic acid or salt thereof, (b) a hydroxymonocarboxylic acid or salt thereof, and (c) an organic solvent selected from aromatic alcohols, alkylene carbonates and polyols at a weight ratio satisfying 0.33&#x2266;[(a)+(b)]/(c)&#x2266;2.5, in which, the weight of each of (a) and (b) is that as an acid, and the composition has a pH at 25&#xb0; C. of from 2.5 to 5 when diluted to 20 times the weight with water; and a method of treating hair, which contains using two hair cosmetic compositions A and B and treating the hair in the order of A&#x2192;B or B&#x2192;A; and a hair quality improving cosmetic set which contains the hair cosmetic compositions A and B: The hair cosmetic composition and method of treating hair according to the invention have excellent effects for improving the elasticity and suppleness of the hair and give good feeling upon use during the treatment.

Detergent composition

The present invention relates to a detergent composition which is primarily used on the skin, and more particularly to a detergent composition which provides comfortable and smooth touch on the skin after cleansing. These compositions comprise:

A 21-substituted steroid compound is disclosed. The compound has a structure of formula (I), ##STR1## wherein R.sup.1 is a hydrogen atom, a lower alkyl, lower alkenyl, lower alkoxy, or phenyl group, R.sup.2 is a hydroxyl group or an acyloxy group having 1-6 carbon atoms, R.sup.3 is a hydrogen atom or a lower alkyl group, or R.sup.2 and R.sup.3 may together form a lower alkylidenedioxy group, X.sup.1 and X.sup.2 may be the same or different and individually represents a hydrogen atom or a halogen atom, Y.sup.1 and Y.sup.2 may be the same or different and individually represents a methylene group or a sulfur atom, Z is a sulfur atom or an imino group, the wave line means that the configuration of R.sup.3 may be of either .alpha. or .beta., and dotted line between the 1 and 2 position means that the bond may be the double bond. It has excellent anti-inflammatory, anti-allergic and anti-asthma activities with little side effects, and is useful for the prevention, cure, and treatment of on inflammation, allergic diseases, rheumatism, and the like.
