The invention relates to a composition used for the treatment of keratin substances which contains at least one amphoteric polymer containing units A and B randomly distributed in the polymer chain, where A denotes a unit derived from a monomer containing at least one basic nitrogen atom and B denotes a unit derived from an acid monomer containing one or more carboxyl or sulphonyl groups, or alternatively A and B can denote groups derived from zwitterionic carboxybetaine monomer, A and B can also denote a cationic polymer chain containing secondary or tertiary amine groups or quaternary ammonium groups, in which chain at least one of the amine groups carries a carboxyl or sulphonyl group joined via a hydrocarbon radical, or alternatively A and B form part of a chain of a polymer with alpha, beta-dicarboxyethylene units, in which one of the carboxyl groups has been reacted with a polyamine containing one or more primary or secondary amine groups, and at least one cationic polymer of the polyamine or poly-(quaternary ammonium) type, containing amine or ammonium groups in the polymer chain or joined to the latter.

Composition for the treatment of keratin fibers, based on amphoteric

Use of 4-(2-oxo-3-bornylidenemethyl)benzenesulphonic acid or its salts for the protection of hair against environmental attacking agents, and in particular against light and process for the protection of hair using this compound. Use of 4-(2-oxo-3-bornylidenemethyl)benzenesulphonic acid or of its salts to preserve the mechanical properties of hair for degradation by environmental attacking agents, and in particular by light. The compound is used in proportions of at least 0.3% by weight of free acid, in a cosmetically acceptable, aqueous, alcoholic or aqueous-alcoholic support, and particularly in proportions of 0.4 to 9% by weight.

Use of 4-(2-oxo-3-bornylidenemethyl)benzenesulfphonic acid or its salts

Process for dyeing keratinous fibers, which comprises applying to these fibers at least one composition (A) containing, in a suitable medium for dyeing, at least one indole derivative and at least one substituted 2-nitro-para-phenylenediamine selected from the group consisting of 1-N-(.beta.-hydroxyethyl)amino-2-nitro-4-N', N'-(bis-.beta.-hydroxyethyl)aminobenzene and 1-N-(.beta.-hydroxyethyl)amino-2-nitro-4-aminobenzene, the color being developed with the aid of an oxidizing system consisting of:

Process for dyeing keratinous fibres and dye composition employing

New compositions for the treatment of keratin material, in particular human hair, skin and nails are provided comprising a combination of a cationic polymer with an anionic polymer. Surprisingly the anionic polymer can be retained well on the hair, even after rinsing, when applied with the cationic polymer.

Composition and process for the treatment of keratin materials with

The present invention is directed to a hair bleach support free of anionic polymers and in a gelable liquid.

Hair dye or bleach supports of quaternized polymers

A cosmetic composition for the treatment of the hair and skin comprises at least 5 weight percent of pulverized particles of at least one plant. The particles have a granulometry lower than 125 microns. The compositions also includes a cohesion agent in an amount to maintain the homogeneity of the composition.

A cosmetic composition for the treatment of the hair and skin comprising, in an aqueous medium, particles of pulverized flowers or flower tops having a granulometry lower than 125 microns and a cohesion agent present in an amount effective to maintain the homogeneity of the composition. The cohesion agent can be a thickening agent, a water-in-oil emulsion or an oil-in-water emulsion.

Cosmetic composition for the treatment of the hair and skin comprising a

A cosmetic composition for overcoming the greasy and unattractive look of hair and skin, comprising at least one oxathiazinone derivative of the formula: ##STR1## in which R.sub.1 denotes hydrogen, alkyl, aryl or acyl; R.sub.2 denoted alkyl or aryl; or alternatively R.sub.1 and R.sub.2, together with the carbon atoms to which they are attached, form an alicyclic radical; and X denotes an alkali metal, together with at least one cosmetic adjuvant.

Cosmetic composition containing oxathiazinones

Detergent and foaming composition, delaying the regreasing of hair, containing a mixture of surface-active agents comprising:

The treatment of keratin substances is described which comprises applying thereto at least one polymer containing one or more cationic groups in combination with an anionic polymer containing vinylsulphonic units of the formula: ##STR1## in which M denotes hydrogen, an alkali metal or alkaline earth metal or an ammonium or amine group, this anionic polymer optionally containing units derived from one or more cosmetically acceptable comonomers.

Composition intended for the treatment of keratin fibres, based on a

A cosmetic composition for the treatment of the hair and scalp comprises in a cosmetically acceptable vehicle a combination of a water soluble polyamide of the poly-beta-alanine type and a nicotinic derivative selected from nicotinic acid or an ester thereof. This composition is employed in a process for improving the regrowth of hair and for delaying or retarding the appearance of an oily aspect of the hair.

Cosmetic composition for the treatment of the hair and scalp containing

This invention has for its object the use of certain quaternized polymers in compositions to protect the hair from the degradation effects of a permanent wave operation. The invention provides for application of said composition to the hair prior to or subsequent to permanently waving of the hair.

Process and composition for protecting the hair from the degradation

A cosmetic composition for the treatment of the hair and skin comprises at least 5 weight percent of pulverized particles of at least one plant. The particles have a granulometry lower than 125 microns. The composition also includes a cohesion agent in an amount to maintain the homogeneity of the composition.

The invention relates to a cosmetic composition for combating the greasy appearance of hair. This composition is characterized in that it contains an active product consisting of a particular polymer derived from chitosan comprising 0 to 30% by weight of units (A), 5 to 50% by weight of units (B), 30 to 90% by weight of units (C), or alternatively preferably 0 to 20% by weight of units (A), 40 to 50% by weight of units (B), 40 to 50% by weight of units (C.sub.1) below; ##STR1## The use of the composition makes it possible to delay the onset of the greasy appearance of the hair.
