An aqueous oxidizing compositions comprising one or more amino acids and hydrogen peroxide are described. The aqueous oxidizing compositions reduce hair damage during chemical services. The effect of hair damage reduction was found to be further improved when polycarboxylic acids were added to bleaching powder, oxidative dyeing, and permanent waving compositions.

Aqueous oxidizing composition comprising amino acids

A cosmetic product, containing a composition A including one or more alkalizing agents, an aqueous composition B having a pH in a range of 1 to 6 and containing one or more oxidizing agents, and a composition C containing one or more compounds selected from the following groups:

Cosmetic product for dyeing keratin fibers

A dyeing composition for keratin fibers, containing one or more alkalizing agents, one or more direct dyes, and one or more compounds selected from the following groups:

Dyeing composition comprising direct dyes

The present invention is directed to a kit-of-parts for bleaching keratin fibers, comprising: an aqueous composition A comprising a) one or more non-acetylated sugar alcohol(s), and/or their mixtures, a bleaching composition B comprising b) one or more persalt(s) and/or peroxy salt(s), c) one or more alkalizing agent(s), and an aqueous oxidizing composition C, wherein the total concentration of compound(s) according to a) in the aqueous composition A is in the range of 1% to 50% by weight, calculated to the total weight of the aqueous composition A, and wherein the bleaching composition B comprises less than 5% by weight of water, calculated to the total weight of the bleaching composition B.

Bleaching composition for keratin fibers

The present invention is directed to a kit-of-parts for bleaching keratin fibers, having a bleaching composition A comprising a) one or more persalt(s) and/or peroxy salt(s), and b) one or more alkalizing agent(s), an aqueous oxidizing composition B, and a composition C comprising c) one or more non-acetylated sugar alcohol(s), and/or their mixtures, wherein the bleaching composition A comprises less than 5% by weight of water, calculated to the total weight of the bleaching composition A.

The present invention relates to a process for semi-permanent straightening and permanent shaping hair, especially human hair, for improved and milder semi-permanent straightening and permanent shaping. It is found out that when commonly used permanent shaping reducing composition is mixed with another composition comprising predominantly carboxylic acids, the permanent shaping effect of the composition is improved, homogeneous shaping of hair fibers is achieved and natural cosmetic properties of hair is maintained and hair may be semi-permanently straightened before such process.

Process for semipermanent straightening and permanent shaping hair

A two-part oxidative dyeing composition is described. The two-part composition has an alkaline first part comprising oxidative dye couplers and/or oxidative dye precursors, and a second part comprising hydrogen peroxide, xanthine and/or its derivatives, and a lipophilic compound. The second part is formulated as water-in-oil emulsion and it was unexpectedly found that xanthines stabilize the viscosity of the second part composition allowing for improved dyeing performance.

Two-part oxidative dyeing composition

The present invention relates to a process for improved and milder permanent shaping of hair, especially human hair. It has been found that when commonly used permanent shaping compositions are mixed with another composition comprising predominantly carboxylic acids, the permanent shaping effect of the composition is improved, homogeneous permanent shaping of hair fibers is achieved and natural cosmetic properties of hair are maintained.

Process for permanent shaping hair

The present invention relates to a process for permanent shaping and dyeing carried out one after another with compositions providing improved and milder shaping and dyeing of hair, especially human hair. The inventors of the present invention have unexpectedly found out that when commonly used permanent shaping and dyeing compositions are mixed with another composition comprising predominantly carboxylic acids, the permanent shaping and dyeing effects of the compositions are improved, homogeneous permanent shaping and dyeing of hair fibers is achieved and natural cosmetic properties of hair are maintained.

Process for treating hair

The present invention relates to a hair bleaching process for improved and milder bleaching, especially for bleaching human hair. The ready-to-use bleaching composition comprises carboxylic acids in addition to bleaching persalts and oxidizing agents added at the time of use.

Process for bleaching hair

The present invention relates to a process for treating hair, especially human hair, wherein the hair is bleached and dyed in a subsequent order with compositions providing improved and milder bleaching and dyeing of hair. The inventors of the present invention have unexpectedly found out that when commonly used bleaching compositions and oxidative dyeing compositions are mixed with another composition comprising predominantly carboxylic acids, the bleaching and dyeing effects of the compositions are improved, homogeneous bleaching and dyeing of hair fibers is achieved and natural cosmetic properties of hair is maintained.

The present invention provides a hair straightening composition with improved ease of use, which leads to an enhanced smoothness of the straightened hair. The composition comprises at least one carboxylic acid of the formula (I) in combination with at least one quaternary ammonium compound having two long-chain hydrocarbon groups: R&#x2014;CO&#x2014;COOH Formula (I). In further aspects, the present invention concerns a process for semi-permanent straightening of the hair, utilizing said composition, the use of the composition for straightening hair, and a kit comprising the composition and a straightening iron.

Composition and process for semi-permanent straightening of hair

The present invention provides a hair straightening composition with improved ease of use and reduced smoke development during the application of a straightening iron. The composition comprises at least one carboxylic acid of the formula (I) in combination with at least one polymeric thickening agent selected from non-ionic, anionic, cationic and amphoteric polymers having a viscosity of at least 500 mPa-s measured at a polymer concentration of 1% by weight, in water and at 20&#xb0; C. with a Brookfield viscometer: R&#x2014;CO&#x2014;COOH Formula (I) In further aspects, the present invention concerns a process for semi-permanent straightening of the hair, utilizing said composition, the use of the composition for straightening hair, and a kit comprising the composition and a straightening iron.
