Abstract: The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains in a cosmetic carrier (A) at least one oxidation dye precursor with 4,5-diaminopyrazole as the basic structural element according to the structural formula (I) and furthermore (B) glucoheptonic acid and/or at least one of its physiologically tolerated salts and/or lactones. The composition as contemplated herein further comprises (C) at least one oxidizing agent other than atmospheric oxygen.

Abstract: The present disclosure relates to cosmetic compositions for the oxidative treatment of keratinous fibers, in particular human hair, comprising at least one salt of a peroxo compound, at least one alkalizing agent and at least one complexing agent. Furthermore, it is an object of the present disclosure to provide a multi-component unit for the oxidative lightening of keratinous fibers, in particular human hair, comprising as first component the cosmetic agent as contemplated herein and as second component an agent comprising H2O2. In addition, the present disclosure relates to the use of a salt of a polyhydroxylated monocarboxylic acid in a cosmetic composition.

Abstract: The present disclosure relates to condensate reaction products that are obtainable by two specific processes. The present disclosure further relates to the use of these condensate reaction products as functional additives in detergent compositions, cosmetic compositions, cleaning compositions and adhesive compositions comprising them.

Abstract: An agent for the oxidative dyeing of keratinic fibers, in particular human hair, contains in a cosmetic carrier (A) at least one oxidation dye precursor with 4,5-diaminopyrazole as the basic structural element, (B) iminodisuccinic acid or a physiologically compatible salt, and (C) at least one oxidizing agent different from atmospheric oxygen.

Abstract: The subject matter of the present disclosure is the use of a combination of succinic acid and ethylene carbonate in a hair bleaching agent to reduce the damage to keratinic fibers due to the oxidative hair lightening.

Abstract: The subject of the present disclosure is a method for coloring of keratinous fibers, particularly human hair, including the following steps in the specified sequence: A) Treatment of the fibers with a hydrous pre-treatment agent (V), B) Treatment of the fibers with a hydrous coloring agent (F), wherein the pre-treatment agent (V) has a pH value of from about 1.0 to about 5.0 and the coloring agent (F) has at least one partially-oxidizing acid dye and a pH value of from about 5.0 to about 9.5. An additional subject of the present disclosure is a multi-component package unit (kit) including a pre-treatment agent (V) and a coloring agent (F).

Abstract: The subject matter of the present disclosure is the use of a combination of succinic acid and ethylene carbonate in a hair bleaching agent to reduce the damage to keratinic fibers due to the oxidative hair lightening.

Abstract: An agent (M) for the treatment of keratin fibers, in particular human hair, containing in a cosmetic carrier, based on the total weight of the agent (M), (a) one or more aliphatic polyols in a total amount from about 1.0 to about 40.0% by weight and (b) one or more cyclic carbonates in a total amount from about 1.0 to about 20.0% by weight, wherein the weight ratio of the total amount of the aliphatic polyols (a) contained in the agent (M) to the total amount of the cyclic carbonates (b) contained in the agent (M), that is, the weight ratio (a)/(b), is a value of from about 40 to about 1.
