Description

The invention relates to an agent for the oxidative color change of keratin-containing fibers, in particular human hair, which contains certain dimeric m-phenylenediamine derivatives with cationic charge, the use of these agents as color change agents of keratin fibers for improving the dyeing results and a process for dyeing keratin-containing fibers, in particular human hair.

The change in the shape and color of the hair is an important area of modern cosmetics dar. For fashionable color design of hairstyles or lamination of gray hair or even white hair with fashionable or natural colors, the consumer accesses to color-changing agents.

To provide color-changing cosmetic agents, in particular for the skin or keratin-containing fibers such as human hair, the skilled person knows various systems depending on the requirements of the coloring or color change.

For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components. The developer components form under the influence of oxidizing agents or of atmospheric oxygen with one another or with coupling with one or more coupler components, the actual dyes. The oxidation colorants are characterized by intensive excellent, long-lasting dyeing results. For natural-looking dyeings, a mixture of a larger number of oxidation dye precursors can be used, and in many cases direct substantive dyes are additionally used for shading.

In particular, oxidative hair dyes are disadvantageous to the user despite their advantageous dyeing properties. In particular, it is assumed for some of the common oxidation dye precursors, including p-phenylenediamine, to act irritating or irritating for some consumers and thereby trigger sensitization or even allergic reactions.

Therefore, there is still room for improvement in their physiological compatibility profile for these substances. In the search for substitutes, many compounds have been explored, but often suffer from application problems, in particular lack of gray coverage. In addition, despite already advanced dyeing systems, there is still a need for dyeing systems that achieve excellent brightness and intensity of dyeing, yet have very good shelf life and excellent homogeneity.

Object of the present invention is therefore to lower the above-mentioned disadvantages of oxidative hair dyes. The colorants should produce intense colorations with high color and good resistance to external influences, in particular with good lightfastness and wash fastness, which suffer no color attenuation or color shift even after repeated shampooing of the hair. In addition, the dyes should be as selective as possible, d. H. achieve as uniform, uniform staining results on differently pretreated hair as possible. In addition, the colorants should have a toxicologically advantageous profile.

It has been found that certain dimeric m-phenylenediamine derivatives with cationic charge as oxidation dye precursors are outstandingly suitable for dyeing keratin-containing fibers. They result in colorations with high color intensity and excellent brilliance as well as excellent gray coverage.

Furthermore, it has proved to be advantageous if the dyeing and whitening agents according to the invention contain further nonionic surfactants. Nonionic surfactants contain as hydrophilic group z. A polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups. Such compounds are, for example

• - Alkylpolyglykoside according to the general formula RO- (Z) _x , wherein R is alkyl, Z is sugar and x is the number of sugar units. The alkyl polyglycosides which can be used according to the invention can only contain one particular alkyl radical R. Usually, however, these compounds are prepared starting from natural fats and oils or mineral oils. In this case, the alkyl radicals R are mixtures corresponding to the starting compounds or corresponding to the particular work-up of these compounds.

Suitable nonionic surfactants are, in particular, C ₈ -C ₂₂ -alkyl mono- and oligoglycosides and their ethoxylated analogs. In particular, the nonethoxylated compounds have been found to be particularly suitable.

• – im Wesentlichen aus C₈- und C₁₀-Alkylgruppen,
• – im Wesentlichen aus C₁₂- und C₁₄-Alkylgruppen,
• – im Wesentlichen aus C₈- bis C₁₆-Alkylgruppen oder
• – im Wesentlichen aus C₁₂- bis C₁₆-Alkylgruppen oder

Preparations having excellent properties are also obtained if they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants.

Particularly preferred non-ionic surface-active substances are substances that are commercially available as solids or liquids in pure form because of their ease of processing. The definition of purity in this context does not refer to chemically pure compounds. Rather, especially when it comes to natural-based products, mixtures of different homologs can be used, for example, with different alkyl chain lengths, such as those obtained with products based on natural fats and oils. Even with alkoxylated products, mixtures of different degrees of alkoxylation are usually present. The term purity in this context refers rather to the fact that the selected substances should preferably be free from solvents, adjuvants and other impurities.

In the case of the surfactants which are adducts of ethylene oxide and / or propylene oxide with fatty alcohols or derivatives of these addition products, both products with a "normal" homolog distribution and those with a narrow homolog distribution can be used. By "normal" homolog distribution are meant mixtures of homologs obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. Narrowed homolog distributions, on the other hand, are obtained when, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with narrow homolog distribution may be preferred.

The anionic, nonionic, zwitterionic or amphoteric surfactants are used in amounts of 0.1 to 45 wt .-%, preferably 1 to 30 wt .-% and most preferably from 1 to 15 wt .-%, based on the total amount of ready for use By means of, used.

Preferred quaternary ammonium compounds are ammonium halides, especially chlorides and bromides, such as alkyltrimethylammonium chlorides, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides, e.g. For example, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, lauryldimethylammonium chloride, lauryldimethylbenzylammonium chloride and tricetylmethylammonium chloride, and the imidazolium compounds known under the INCI names Quaternium-27 and Quaternium-83. The long alkyl chains of the above-mentioned surfactants preferably have 10 to 18 carbon atoms. Further cationic surfactants which can be used according to the invention are the quaternized protein hydrolysates.

The alkylamidoamines are usually prepared by amidation of natural or synthetic fatty acids and fatty acid cuts with dialkylaminoamines and are characterized in addition to a good conditioning effect especially by their good biodegradability. An inventively particularly suitable compound from this group of substances under the name Tegoamid ^® S 18 commercial stearamidopropyl dimethylamine is.

Likewise very readily biodegradable are quaternary ester compounds, so-called "ester quats". Esterquats are known substances which contain both at least one ester function and at least one quaternary ammonium group as a structural element. Preferred ester quats are quaternized ester salts of fatty acids with triethanolamine, quaternized ester salts of fatty acids with diethanolalkylamines and quaternized ester salts of fatty acids with 1,2-dihydroxypropyldialkylamines.
