The orthodiphenols have the following general structure: where R, R, and Rare independently selected from H, OH, halogen, C-Clinear or branched alkyl or alkenyl, O—X, NO, COOH, SOH, aryl, and heteroaryl, and X is a C-Clinear or branched alkyl. The imidazolidin-2,4-diones have the following general structure: where R, R, and Rare independently selected from H, OH, halogen, C-Clinear or branched alkyl or alkenyl, O—X, COOH, phenyl, diphenyl, ureyl, and X is a C-Clinear or branched alkyl.

Aqueous oxidative composition comprising orthodiphenols or imidazolidin-2,4-dione derivatives

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 method for dyeing keratin fibers, including mixing an aqueous dyeing composition containing a dye compound which is an anionic azo dye, a non-ionic azo dye, a salt thereof, or a mixture thereof, and an alkalizing agent having at least one basic functional group whose conjugated acid has a pKa value in a range of 6.0 to 8.0, with a second aqueous composition having a pH in a range of 1 to 6 to yield a ready-to-use composition having a pH in a range of 7 to 12. The method further includes applying the ready-to-use composition onto the keratin fibers and leaving it for a time period in a range of 1 min to 60 min, and rinsing-off the keratin fibers. The alkalizing agent is triethanolamine, 2-[4-(2-hydroxyethyl)-piperazin-1-yl]-ethane-1-sulfonic acid, a salt thereof, or a mixture thereof.

Dyeing method for keratin fibers comprising a direct azo-dye and an organic alkalizing agent, and kit-of-parts thereof

A dyeing composition for keratin fibers, including one or more first direct dyes selected from HC Blue 18, HC Red 18, HC Yellow 16, and salts thereof, one or more second direct dyes selected from Disperse Black 9, Acid Yellow 1, 2-amino-6-chloro-4-nitrophenol and salts thereof, and one or more alkalizing agents.

Hair dyeing composition with improved durability

A cosmetic product, including a composition A containing one or more alkalizing agents and one or more direct dyes, and an aqueous composition B having a pH in a range of 1 to 6. The aqueous composition B contains hydrogen peroxide, and one or more compounds selected from the following groups:

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

Reshaping compositions, methods or processes, and kits-of-part reshape keratin fibers. The reshaping composition is a non-reducing, non-oxidizing composition for keratin fibers having a pH in the range of 7 to 12, and comprising a) one or more organic alkalizing agents having a pKof less than 9.0, b) one or more lipophilic compounds being liquid at 25° C. and atmospheric pressure, at a total concentration in the range of 10% to 80% by weight, calculated to a total weight of the composition, c) one or more surfactants, and d) one or more thickening agents.

Reshaping 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.

Processes and kits-of-parts reshape keratin fibers and comprise applying a composition on to keratin fibers and cover the keratin fibers, wherein the composition comprise an alkalizing agent, a thickening polymer, and an organic solvent. Additionally, the keratin fibers are put under tension using a curler along with covering the curler with a moisture barrier, and heating the keratin fibers. As a result, long-lasting curl having cosmetic properties are achievable.

Process for reshaping keratin fibers

Processes and kits-of-parts reshape keratin fibers by applying a composition onto hair and covering the hair, wherein the composition comprises ammonia and one or more organic alkalizing agents. Additionally, the hair is put under tension using a curler with covering the curler with a moisture barrier, and heating the keratin fibers. As a result, long-lasting curl having cosmetic properties are achievable and an ammonia smell is reduced when directly compared to compositions having no organic alkalizing agent.

A dyeing composition for keratin fibers, including one or more direct dyes selected from HC Blue 18, HC Red 18, HC Yellow 16, and salts thereof, and tris-(hydroxymethyl)-aminomethane and salts thereof. A method for dyeing keratin fibers, including mixing the composition with a second aqueous composition having a pH in a range of 1 to 6 and optionally including one or more oxidizing agents to yield a ready-to-use composition having a pH in a range of 7 to 12, applying the ready-to-use composition onto the keratin fibers and leaving it for a time period in a range of 1 min to 60 min, and rinsing-off the keratin fibers and optionally shampooing the keratin fibers.

Dyeing composition for keratin fibers comprising a direct dye and an organic alkalizing agent, method for dyeing; and kit-of-parts thereof

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

The present invention is directed to a dyeing composition, method, use and kit thereof, which improves dyeing using specific direct dyes. The inventive composition comprises benzyl alcohol, and a thickening polymer.
