2-hydroxypropanediamine derivative and detergent composition containing

A hair cosmetic is disclosed which comprises the following components (A), (B) and (C):

Hair cosmetic containing a cationic surfactant, fat and oil and an alkyl

A shampoo composition containing the following ingredients (a), (b), (c), and (d):

Shampoo composition

A N-alkylcarbamylalkanol sulfate or a salt thereof represented by the following general formula (1-1), a process for producing the same, and a detergent composition containing the same, which is useful as a detergent for hair, body or tableware and has not only excellent foaming power and detergency but also high safety: ##STR1## wherein R.sup.1 represents a linear or branched alkyl or alkenyl group having 6 to 22 carbon atoms; R.sup.2 represents an alkyl or alkenyl group having 1 to 22 carbon atoms or a hydrogen atom: R.sup.3 represents a linear or branched alkylene group having 1 to 5 carbon atoms; R.sup.4 O represents an oxyalkylene group having 2 or 3 carbon atoms; Ma represents a hydrogen atom, an alkali metal atom, an ammonium group, etc.; and n represents a number between 0 and 20.

N-alkylcarbamylalkanol sulfate or salt thereof, process for producing

Hair cosmetic composition

A toiletry composition for hair care which is not irritative to the hair and skin and has an excellent conditioning effect and which comprises:

Toiletry composition for hair care

A hair cosmetic composition comprising a branched fatty acids of the following formula (1), ##STR1## wherein R.sup.1 is a methyl or ethyl group, n is an integer of 4-16, and R.sup.2 is an amino, alkoxy, or glycerol group. The composition imparts excellent sensation to hair and prevents hairs from being damaged.

Cosmetic composition

Hair care compositions which contain the following ingredients (a) and (b):

Hair care composition containing aromatic alcohol and glycolic acid

A composition for hair treatment such as hair rinse, shampoo, or hair conditioner, contains (a) 0.1-10 wt. % of a modified silicone polymer having at least one alkoxy group in the molecule and a melting point of not lower than 30.degree. C., (b) 0.1-20 wt. % of a cationic surface active agent, (c) 0.1-30 wt. % of an oily or fatty material, (d) 0.1-90 wt. % of an organic liquid which is compatible with water and of which molecule has at least one hydroxy group, and (e) water.

Composition for hair treatment

A cationic compound is useful for a cleaning agent such as shampooing and defined by the formula (I): ##STR1## in which R1 is straight or branched and an alkyl having 7 to 15 carbon atoms or an alkenyl having 7 to 15 carbon atoms; R2, R3 and R4, independently of one another, are an alkyl having 1 to 3 carbon atoms; G is hydrogen atom, an alkyl having 1 to 3 carbon atoms or a hydroxyalkyl having 1 to 3 carbon atoms, E is hydrogen atom, an alkyl having 1 to 3 carbon atoms, a hydroxyalkyl having 1 to 3 carbon atoms or an ammonium group having the formula (II): ##STR2## Y being hydrogen atom or hydroxy, A being hydroxy, a halogen atom or an alkylsulfate having 1 to 4 carbon atoms, m being 2 or 3, n being zero or an integer of 1 to 5, provided that (1) when G is an alkyl or a hydroxyalkyl, E is neither an alkyl nor a hydroxyalkyl, (2) when n is 1, Y is hydrogen atom or hydroxy and when n is zero, 2, 3, 4 or 5, Y is hydrogen atom and (3) G and E cannot both be hydrogen.

Mild cationic surfactants having good foaming conditioning properties

A shampoo composition is disclosed. The composition comprises an amidoamine-type amphoteric surface active agent, a specific type of modified silicone polymeric compound, and a specific type of polymer. It gives an excellent soft and smooth feeling during washing and rinsing, a superb natural hair-set effect without oily stickiness and roughness, and easy passage of comb through the hair. It is also mild to the skin, the mucous of the eyes, and the like.

The present invention provides a novel betaine compound represented by the general formula: ##STR1## wherein R.sup.1 is a straight-chain or branched alkyl, alkenyl or hydroxyalkyl group having 8 to 22 carbon atoms; X is H or a hydroxyl group; R.sup.2, R.sup.3 and R.sup.4 each represent an alkyl group having 1 to 4 carbon atoms; Y is --CH.sub.2 CH(OH)CH.sub.2 SO.sub.3, --(CH.sub.2).sub.n SO.sub.3 or --(CH.sub.2).sub.m CO.sub.2 ; n is 2 to 5; m is 1 to 5; and l is 0 to 5; a process for the preparation of the same; and a detergent composition containing the same. This detergent composition exhibits excellent foaming power and detergency and is lowly irritant, thus being suitable for a base of a body or hair shampoo.

Betaine compound and detergent composition

The present invention provides a novel betaine compound represented by the general formula: ##STR1## wherein R.sup.1 is a straight-chain or branched alkyl, alkenyl or hydroxyalkyl group having 8 to 22 carbon atoms; X is H or a hydroxy group; R.sup.2, R.sup.3 and R.sup.4 each represent an alkyl group having 1 to 4 carbon atoms; Y is --CH.sub.2 CH(OH)CH.sub.2 SO.sub.3, --(CH.sub.2).sub.n SO.sub.3 or --(CH.sub.2).sub.m CO.sub.2 ; n is 2 to 5; m is 1 to 5; and l is 0 to 5; a process for the preparation of the same; and a detergent composition containing the same. This detergent composition exhibits excellent foaming power and detergency and is lowly irritant, thus being suitable for a base of a body or hair shampoo.
