Abstract: Multi-component package unit (kit-of-parts), ready-to-use agent, and methods for reductive decolorizing of dyed keratinous fibers are provided herein. In an embodiment, a multi-component package unit includes, separately packaged, a first container (A), a second container (B), and a third container (C). The first container (A) includes a cosmetic agent (a) that includes (a1) one or multiple reducing agents chosen from the group of formamidine sulfinic acid, sodium dithionite, zinc dithionite, potassium dithionite, hydroxymethanesulfinic acid, aminomethanesulfinic acid, cysteine, thiolactic acid, sulphanylacetic acid (thioglycolic acid) and/or ascorbic acid. The second container (B) includes a cosmetic agent (b) that includes one or multiple oxidizing agents. The third container (C) includes a cosmetic agent (c) that includes (c1) one or multiple alkalizing agents. The weight ratio of the total amount of all reducing agents (a1) to the total amount of all oxidants (b1) has a value from about 50.0 to about 4.0.

Abstract: A composition for oxidatively treating hair includes—50-96 wt. % water; 0.5-20 wt. % hydrogen peroxide; at least one linear saturated 1-alkanol with 12-30 carbon atoms in a total volume of 2.7-6 wt. %; at least one polyethylene glycol ether of a linear saturated C12-C22 alkanol with 15-30 ethylene oxide units in the molecule, in a total volume of 0.3-1 wt. %; at least one anionic surfactant in a total volume of 0.3-1 wt. %; at least one cellulose ether in a total volume of 0.1-0.5 wt. %; and at least one oil in a total volume of 0.1-0.5 wt. %. The composition is highly suitable as an oxidant for powdered color preparations, containing oxidizing coloring intermediates and also pigments, which do not permanently change the color of the fibers, as well as, optionally, including solid inorganic alkalizing agents, as well as, optionally, ammonium salts, like ammonium chloride and ammonium sulfate, in particular with respect to the application properties of the application mixture.

Abstract: A method for the permanent shaping and color modification of keratinic in a single process includes the following steps. First, an aqueous composition, including at least one keratin-reducing compound and at least one alkalizing agent, is applied to the keratinic fibers and is left on the keratinic fibers for a period of 5 to 50 minutes at a temperature of 20 to 45° C. The keratinic fibers are rinsed, and optionally dried. Next, a composition including at least one oxidation dye precursor and at least one oxidizing agent is applied to the keratinic fibers and the keratinic fibers are deformed. That composition is allowed to act for 10 to 35 minutes. An aqueous composition including at least one oxidizing agent, is applied to the keratinic fibers for 30 seconds to 15 minutes. The keratinic fibers are rinsed out, along with removal of the deformation aids.

Abstract: Method for simultaneously and permanently reshaping and coloring keratin fibers, particularly human hairs, in a single process in which the keratinic fibers are first waved by means of a foam-type waving agent (M1) and then lightened or colored by means of a foam-type coloring agent (M2). The permanent wave is simultaneously fixed by the oxidizing agent included in the oxidative dyeing agent. The method according to the invention brings about a uniform waving and coloring result and causes little or no damage to the hair.

Abstract: A method for the permanent shaping and color modification of keratinic fibers, in a single process, includes the following method steps in sequence: deforming keratinic fibers, using deformation aids, applying an aqueous composition, including at least one keratin-reducing compound and at least one alkalizing agent, to the keratinic fibers situated on the deformation aids, and leaving this composition for a period of 5 to 50 minutes, rinsing the keratinic fibers situated on the deformation aids, applying a composition, including at least one oxidation dye precursor, at least one oxidizing agent, at least one alkalizing agent, and at least one surfactant, as foam from an applicator to the keratinic fibers situated on the deformation aids, and leaving this composition for a period of 10 to 45 minutes, removing the deformation aids from the keratinic fibers and rinsing the keratinic fibers, and optionally applying an aftertreatment agent to the keratinic fibers.

Abstract: The present invention relates to a product for coloring and/or lightening keratinic fibers, more particularly human hair, and to a method for employing this product. The product of the invention comprises three compositions, which are kept separate from one another until being employed. The invention further relates to the use of this product for improving absorption of color in the coloring of keratinic fibers, the use thereof to enhance the wash stability of colored keratinic fibers, and the use thereof to enhance the conditioning of keratinic fibers.
