Description

  The present invention relates to an agent for altering the color of keratin materials containing human keratin fibers such as hair. Agents for changing the color of keratin fibers include a color base composition containing a fatty substance and a rheology modifying polymer and an oxidizing composition containing an oxidizing agent.

  Cosmetic and personal care compositions that improve the appearance of keratin fibers, such as hair, by the consumer changing the color of the hair and / or imparting various properties such as gloss and conditioning to the hair Is known to want to use. The process of changing the color of the hair involves applying artificial colors to the hair that give the hair a different shade or color or, for example, from dark brown to medium brown or light brown tones. Can be included.

  Conventional hair dye products, in most cases, contain a composition containing an oxidation dye precursor, also known as an initial intermediate or oxidation base, under alkaline pH conditions, and a peroxide and peroxide. Includes persistent hair coloring products, also known as oxidative dyeing, using a combination with oxidizing products containing oxidizing agents such as sulfate compounds. In general, the oxidative dye precursor comprises an oxidation base selected from ortho- or para-phenylenediamine, ortho- or para-aminophenol, and heterocyclic compounds. These oxidation bases are colorless or light colored compounds that, when combined with an oxidizable product, can produce colored species through the process of oxidative condensation.

  The tones obtained with these oxidation bases can often be changed by combining them with at least one coupler, which can be, for example, aromatic meta-diamines, meta-aminophenols, meta- -Selected from specific heterocyclic compounds such as diphenols and indole compounds. A wide range of colors can be obtained with various molecules used as oxidation bases and couplers.

  Oxidizing agents used in persistent dyeing compositions can degrade hair melanin, which can result in less noticeable lightening of the fibers, depending on the nature of the oxidizing agent present. Here, in the case of relatively weak lightening, the at least one oxidant can be, for example, hydrogen peroxide. If more pronounced lightening is desired, a peroxygenated salt such as persulfate can be used in the presence of hydrogen peroxide.

  The hair dye composition typically contains aqueous ammonia for activating the oxidizing agent as an alkalizing agent. These alkalizing agents also cause the hair shaft to swell, thereby allowing small oxidative dye molecules to penetrate the stratum corneum and cortex before the oxidative condensation process is complete. The larger sized colored complex resulting from the oxidation reaction is then trapped inside the hair fibers, thereby permanently changing the color of the hair. However, not only because of the undesirable odor of ammonia, but also because ammonia can also have a higher risk of intolerance, such as, for example, scalp irritation and stinging, the use of ammonia is Can affect.

  The option of using at least one other standard alkalizing agent instead of all or at least a portion of the aqueous ammonia often results in compositions that are as efficient as those based on aqueous ammonia. The reason for this is that, for example, these alkalizing agents may not provide sufficient lightening of the colored fibers in the presence of an oxidizing agent.

  Accordingly, there is a need in the art for improved and / or alternative dyeing methods that are performed in the presence of at least one oxidizing agent that do not have at least one of the disadvantages of existing methods.

  In order to improve the performance of such hair dye compositions, the use of new additional ingredients and new combinations of ingredients continues to be sought; however, the choice of ingredients depends on their application, rheology or The dyeing / composition of the composition without adversely affecting other properties of the composition such as viscosity properties, stability and / or without causing more defects such as increased damage to the hair or unhealthy appearance Difficulties can arise if the lightening function must be improved.

  Various types so that the composition can be provided in the form of a liquid-lotion, liquid-gel, liquid emulsion such as liquid-cream, or cream emulsion such as a high viscosity cream or gel-cream, or foam or mousse. It is also important to provide a hair dye composition having a consistency of, wherein the liquid emulsion form has a lower viscosity consistency than the cream emulsion form and is typically packaged in a bottle. Liquid emulsion forms are commonly used when the hair of the entire head is colored or a single color is desired because the dye composition spreads easily and allows a wider coverage, whereas cream emulsion forms It can be used for dyeing the whole hair and highlighting or lightening only certain parts of the hair.

  The object of the present invention is therefore to obtain a novel composition for oxidative dyeing of hair. Another object of the present invention is that it has a unique, non-drip consistency or rheology and further spreads easily in the hair while others such as conditioning, healthy appearance, gloss etc. To obtain a hair coloring composition with less damage to the hair.
