Problems solved by technology

[0018] This phenomenon is even more undesirable when the components are mixed just before application to the fibers: the gradual swelling of the mixture over time prevents its application to the fibers and makes its application less accurate
This may also result in poor uniformity of staining and / or bleaching

Embodiment approach

[0053] According to a preferred embodiment of the invention, composition (A) does not contain any ammonia.

[0054] According to a preferred embodiment of the invention, when the composition (A) contains ammonia or its salt, it also contains one or more alkanolamines, and one or more alkanolamines in the composition ( The weight in A) is greater than the weight of ammonia in the same composition.

[0055] Generally, the content of one or more alkalizing agents of the composition (A) ranges from 0.1% to 40% by weight, preferably from 0.5% to 20% by weight, relative to the weight of the composition.

[0056] Preferably, composition (A) has a pH greater than or equal to 8 and more preferably a pH in the range of 8.5 to 11.5.

[0057] The pH can also be adjusted to the desired value by using one or more acidifying agents in addition to the alkalizing agent.

[0058] Among the acidifying agents, examples that may be mentioned include inorganic or organic acids, such as hydrochlor...

no. 1 approach

[0214] According to a first embodiment of the invention, composition (A) also comprises one or more oxidation dyes.

[0215] In this case, the agents according to the invention are advantageously used for the oxidative dyeing of keratin fibers.

[0216] In this embodiment, composition (A) may also comprise one or more direct dyes.

no. 2 approach

[0217] According to a second embodiment of the invention, composition (A) also comprises one or more direct dyes.

[0218] In this case, and when the composition (A) does not comprise any oxidation dyes, the agents according to the invention are advantageously used for the bright direct dyeing of keratin fibers.

[0219] Oxidation dyes which may be used in the present invention are generally selected from oxidation bases, optionally in combination with one or more couplers.

[0220] The oxidation bases may be chosen in particular from p-phenylenediamines, bis(phenyl)alkylenediamines, p-aminophenols, ortho-aminophenols, and heterocyclic bases and their addition salts.

[0221] Among the p-phenylenediamines that may be mentioned are for example p-phenylenediamine, p-toluenediamine, 2-chloro-p-phenylenediamine, 2,3-dimethyl-p-phenylenediamine, 2,6- Dimethyl-p-phenylenediamine, 2,6-diethyl-p-phenylenediamine, 2,5-dimethyl-p-phenylenediamine, N,N-dimethyl-p-phenylenediamine, N, N-d...

Abstract

The present disclosure relates to an agent for dyeing and / or bleaching keratin fibers formed by: a first composition (A) comprising at least one basifying agent,and a second composition (B) comprising at least one oxidizing agent,wherein at least one of the two compositions (A) and (B) comprises at least one fatty substance not containing any carboxylic acid functional groups,the total amount of fatty substances in the mixture of compositions (A) and (B) representing at least 20% by weight relative to the total weight of the mixture of these compositions,and a t least one of the compositions (A) and (B) comprises at least one sequestrant chosen from those of formula (I) and acids thereof.The present disclosure also relates to a process for dyeing and / or bleaching keratin fibers using the agent, and to a kit containing thereof.

Description

[0001] This application is an application date of December 21, 2010, the application number is 201010602925.5, and the invention title is "a double reagent for dyeing and / or bleaching of keratin fibers containing fatty substances and chelating agents". case application. technical field [0002] The present invention relates to an agent in two parts for dyeing and / or bleaching keratin fibers, especially human keratin fibers such as hair. [0003] More specifically, the subject of the invention is an agent for dyeing and / or bleaching keratin fibers, formed from a first composition (A) and a second composition (B), said first composition (A) contains one or more basifying agents and optionally one or more dyes, while the second composition (B) contains one or more oxidizing agents, the two compositions (A) and at least one of (B) comprising one or more fatty substances which do not contain any carboxylic acid functionality and one or more specific chelating agents. [0004] The...
