Cationic surface-active agents which are polyhydroxylated tertiary amines or the quaternary ammonium salts thereof and which are usefully employed in cosmetic compositions, are prepared by condensing on a fatty alcohol, glycerol epihalohydrin alone or together with an epoxide to form polyhalogenated polyethers, which in turn are converted to polyhalogenated glycidyl ethers, the latter being reacted with a secondary amine to form polyhalogenated tertiary amines which are then reacted with sodium or potassium acetate in the presence of a diol to form said polyhydroxylated tertiary amines.

Cationic surface-active agents

A two-stage process for producing indoanilines includes oxidizing in a first stage a paraphenylene diamine to a quinone diimine and in a second stage condensing the said quinone diimine with a phenolic compound. The resulting indoanilines can be incorporated into a dye composition for keratinous fibers, especially, human hair.

Process for producing indoanilines and keratin fiber dye composition

A process is described which consists, in a first stage, in applying a composition based on a substance of vegetable or animal origin, a synthetic organic substance or a mineral substance, in suspension or in solution in a solvent and having a viscosity suitable for application to the hair, or as a powder, and making it possible to prevent or substantially to limit the passage of the dyestuffs and/or of the dyestuff precursors as far as the scalp, and, in a second stage, in dyeing the hair using one or more compositions, at least one of which contains either an oxidizable dyestuff or a direct dyestuff, the dyeing being followed, after an interval sufficient for coloring the hair, by rinsing and optionally by shampooing.

Hair-dyeing process involving protection of the scalp

A method, composition and compounds useful in said compositions for treating the skin and scalp characterized by an excessive secretion of sebum to improve the condition thereof by reducing said excessive secretion of sebum includes topically applying to a human having skin and/or a scalp so characterized a cosmetic composition containing as an active ingredient a derivative of cysteine or cysteamine. The composition contains about 0.1-5 weight percent of said derivative and also contains as a carrier for the active ingredient, water, a mixture of water and a lower alkanol, a lower alkanol, a mixture of a lower alkanol and a cosmetic resin, a reducing agent, a neutralizing agent or a vegetable oil.

5-Ureido-3-thia hexanedioic acid

New dyestuffs are described for keratinic fibers which produce particularly luminous shades without the need for an oxidizing agent. These dyestuffs have the formula: ##STR1## or a tautomeric form thereof wherein each of R.sub.1 and R.sub.4, which may be identical or different, represents a member selected from hydrogen, halogen, alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, acylamino and ureido;

N-Monosubstituted indoanilines

Novel meta-phenylenediamines are provided for use as couplers with dye bases in hair dye compositions. These meta-phenylenediamines have the formula: ##STR1## in which n is 2, 3 or 4. Their acid addition salts may also be used.

Meta-phenylenediamines, dyeing compositions in which they are present

The invention resides in the use of the compounds having the formula given below, or an acid salt thereof, as couplers in dyeing compositions for keratin fibres which contain an oxidation base: ##STR1## in which formula n is equal to 2, 3 or 4 and R.sub.1 and R.sub.2 are identical or different and represent an alkyl group having from 1 to 4 carbon atoms.

Dyeing compositions for keratin fibres containing meta-phenylenediamines

A cationic surfactant of the formula ##STR1## wherein R' represents a hydrocarbon radical containing up to 30 carbon atoms and derived from lanolin, natural waxes or resin acids, n is a number between 0.5 and 10, and R.sub.1 and R.sub.2 each independently represent lower alkyl or lower hydroxyalkyl, or together form a heterocycle such as morpholinyl or piperidinyl, is used to prepare cosmetic compositions for application to the skin or hair. Preferably, R' in the surfactant is derived from the alcohols of lanolin and hydrogenated lanolin.

Cationic surfactants

Diphenylamine of the formula ##STR1## wherein R.sub.1 and R.sub.4 each independently represent a member selected from the group consisting of hydrogen, halogen, lower alkyl having 1-6 carbon atoms, lower alkoxy having 1-6 carbon atoms, amino, lower alkyl amino wherein the alkyl moiety has 1-6 carbon atoms, acylamino, lower carbamylalkyl amino wherein the alkyl moiety has 1-6 carbon atoms, lower hydroxyalkyl amino wherein the alkyl moiety has 1-6 carbon atoms, lower carbalkoxy amino wherein the alkoxy moiety has 1-6 carbon atoms and ureido;

N,N-Dialkylamino diphenylamines and the use thereof in compositions for

Indoaniline of the formula ##STR1## wherein R.sub.1 represents hydrogen, halogen, alkyl or alkoxy; R.sub.2 and R.sub.3 represent alkyl; R.sub.4, R.sub.5 and R.sub.6 each independently represent hydrogen, halogen, alkyl, alkoxy, acylamino, ureido or carbalkoxyamino and R.sub.5 can also represent amino, alkylmaino, hydroxy alkylamino or carbamylalkylamino, the alkyl and alkoxy groups above being able to contain 1 to 6 carbon atoms and the acyl group from 2 to 7 carbon atoms with the condition that R.sub.5 does not represent hydrogen, chlorine, methyl or methoxy and when R.sub.5 represents acetylamino, R.sub.6 does not represent hydrogen; it being understood that the above compounds can be present in the tautomeric form of that represented by formula (I). The indoaniline is usefully employed in dye copositions for keratinic fibers, especially living human hair.

Indoanilines, process for producing the same and keratinic fiber dye

Quinonediimine intermediates for indoanilines

Diphenylamine which is N-monosubstituted in the 4'-position carries at least one acylamino group at the 2- or 6-position. The diphenylamine is usefully employed in a composition for dyeing keratinic fibers.

Diphenylamines N-monosubstituted in the 4'-position and the use thereof

A dye for keratinic material comprises a water-soluble cationic polymer having a molecular weight ranging between about 800 and 10,000 and having secondary, tertiary or quaternary ammonium amine groups wherein said amine groups are either a part of, or aid in the direct or indirect linking to the polymer chain, an aryl or arylaliphatic chromophore or chromogen group carrying compound, with the proviso that when the main chain of the polymer has amine groups derived from the said chromophore or chromogen group carrying compound, the said main chain must also have at least 10 percent aliphatic amine groups relative to the total number of amine groups of the said chain.
