The present invention relates to an aqueous oxidizing composition comprising one or more oxidizing agent, one or more sugar and/or one or more polyethylene glycol and having a pH in the range of 1 to 5.

Aqueous oxidizing composition

The present invention relates to a hair dyeing composition comprising select hair direct dyes and a reducing agent in order to color hair homogeneously, intensively and durably.

Hair dyeing composition

The present invention relates to novel direct dyes and compositions comprising them for dyeing keratin fibers especially human hair. The novel dyes of the present invention have benzothiophene structure providing intensive and homogeneous dyeing on keratin fibers, especially human hair.

Direct dyes and composition comprising the dyes

Present invention relates to an aqueous composition for bleaching and coloring hair which comprises direct dyes and an oxidizable solvent in addition to a compound with a bleaching effect, an alkalizing agent and an oxidizing agent. It is furthermore the object of the present invention is the use of oxidizable solvent, preferably an aromatic or aliphatic alcohol for stabilizing a direct dye in an aqueous composition comprising at least one compound with hair bleaching effect, at least one oxidizing agent and at least one alkalizing agent.

Bleaching and colouring composition for hair

The present invention relates to bleaching composition for keratin fibers, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a calcium salt. Further object of the present invention is the use of at least one calcium salt in a bleaching and/or highlighting composition for keratin fibers, especially for human hair, comprising at least one compound with bleaching and/or highlighting effect for preventing temperature increase going above 40&#xb0; C., preferably above 45&#xb0; C. and more preferably above 50&#xb0; C. in a period of at least 60 min after mixing water free bleaching and/or highlighting composition and oxidizing lotion.

Bleaching/highlighting composition containing calcium salts

Present invention relates to an aqueous oxidizing composition comprising at least one oxidizing, at least one alkyl or alkanol amine, urea, at least one carbonate salt and at least one natural triglyceride. Composition comprises furthermore hair dyes.

The present invention relates to bleaching composition for keratin fibres, especially human hair, comprising at least one compound with bleaching and/or highlighting effect and a calcium salt. Further object of the present invention is the use of at least one calcium salt in a bleaching and/or highlighting composition for keratin fibres, especially for human hair, comprising at least one compound with bleaching and/or highlighting effect for preventing temperature increase going above 40&#xb0; C., preferably above 45&#xb0; C. and more preferably above 50&#xb0; C. in a period of at least 60 min after mixing water free bleaching and/or highlighting composition and oxidizing lotion.

Present invention relates to an oxidizing composition for keratin fibers especially for human hair with improved lightening effect and therefore, improved colouring and bleaching effects are easily achieved of the compositions applied after mixing with the said composition. Present inventors have surprisingly found out that a composition comprising at least one oxidizing agent and additionally at least one alkalizing agent, at least one carbonate source and at least one urea derivative delivers an improved and homogeneous lightening performance and leaves hair in an improved cosmetically acceptable conditioned status.

Oxidizing composition for hair

Present invention relates to an oxidizing composition for keratin fibers especially for human hair with improved lightening effect and therefore, improved coloring and bleaching effects are easily achieved of the compositions applied after mixing with the said composition. Present inventors have surprisingly found out that a composition comprising at least one oxidizing agent and additionally at least one alkalizing agent, at least one carbonate source and at least one urea derivative delivers an improved and homogeneous lightening performance and leaves hair in an improved cosmetically acceptable conditioned status.

Present invention relates to the use of a cationic anthrachinone dye for coloring keratin fibers, especially human hair, and compositions comprising the said dyestuffs. The object of the present invention is the use of dyestuff according to general structure wherein Ris a group selected from CH, CHOH, CHOH, CH, CHOCH, CHOCHand CHOCHOCHfor dyeing keratin fibers especially human hair.

Use of dyestuffs for dyeing keratin fibers and compositions comprising the dyestuffs

Present invention relates to a coloring composition for keratin fibers especially for human hair with exceptionally improved color and shade stability. Accordingly, the first object of the present invention is a coloring composition for keratin fibres especially human hair comprising, in a cosmetically acceptable medium, at least one oxidative dyestuff precursor, 1,3-bis(2,4-diaminophenoxy) propane and/or its respective salts as a coupling agent and at least one direct dye. In an especially preferred from of the present invention the coloring compositions are substantially free from mono cyclic m-phenylenediamine coupling agent. With the term 'mono cyclic m-phenylenediamine', it is meant that the compound comprises only one cyclic group, preferably a benzene ring, in its molecule.

Colouring composition for keratin fibres

The present invention refers to dyestuffs of the general Formula (I) wherein R, X, Y and Z are defined as given in claim 1, dyestuff mixtures and hair dye compositions comprising them, as well as a process for coloring hair. 

Dyestuffs and hair dye compositions

Provided is a hair dye composition containing a dissociative direct dye (1): (wherein Ar represents an aromatic group or heterocyclic aromatic group which may have a substituent, Ar' represents an aromatic group which may be substituted by an alkyl group or an electron drawing group, or a specific heterocyclic aromatic group, and W represents an electron drawing group); or salt thereof.

Hair dye composition

A hair dye composition containing an azo dye (1) or a salt thereof, (wherein Rto Rrepresents H, aliphatic hydrocarbon group, aryl group, halogen atom, acyl group, cyano group, acylamino group, or the like, wherein Rand R, and/or Rand Rmay be coupled to form a 5- or 6-membered ring; X represents C or N, with the proviso that when X represents C, n stands for 1, and when X represents N, n stands for 0; A, A, Aand Aeach represents N or represents C substituted by Y or having H, with the proviso that at least one of A, A, Aand Ais a nitrogen atom; and Y represents a substituent with the proviso that m stands for an integer from 0 to 3).

A hair dye composition containing an azo dye (1) or a salt thereof: wherein R represents a coupler moiety, Rand Reach independently represent &#x2014;SOM, &#x2014;SONRRor a hydrogen atom, R, Rand Reach independently represent a hydrogen atom or a substituent, and M represents a hydrogen atom, metal atom or ammonium, with a proviso that Rand Rare not hydrogen atoms at the same time.
