Description

Dyeing compositions in aqueous alcohol media This invention relates to a dyeing composition for use in an aqueous alcohol-based medium for keratin fibers, comprising a dye and certain surfactants. Conventional liquid hair dyeing compositions with low viscosity utilize ethoxylated surfactants, which are dissolved in an aqueous alcoholic medium by means of anionic surfactants. Upon mixing with a second reagent, spontaneous gel formation occurs, increasing viscosity and allowing safe application to the consumer's hair without dripping. However, the resulting ready-to-use compositions leave a poor hair feel, leading to consumer dissatisfaction. Cationic surfactants typically enhance the feel of food. However, combining nonionic surfactants with cationic surfactants in aqueous alcoholic compositions often causes stability problems in ready-to-use compositions, resulting in the composition dripping onto the consumer's head or even face during color application. While improving the cosmetic appearance of colored hair, the prior art has not solved the problem of dripping of ready-to-use mixtures produced by prior liquid compositions with water-like viscosity. Therefore, the first objective of this invention is an aqueous alcohol-based dyeing composition A having a pH in the range of 6 to 12 for keratin fibers, preferably for human keratin fibers, and more preferably for human hair, comprising: a) one or more hair dyes, b) one or more C 2-C 4) Monohydric alcohols, dihydric alcohols, or trihydric alcohols and / or mixtures thereof; c) one or more nonionic surfactants having an HLB value of 11 or less; d) one or more quaternary ammonium surfactants according to the following structure: Where R 1 and R The 2 series is independently selected from C 1 to C 22 Alkyl or alkylene, wherein the limitation is at least R Series 1 is selected from C 17 To C 22 Alkyl or alkylene, R 3 and R The 4 series is independently selected from C 1 to C 4 alkyl or alkylene, and X -The ions are halogen, sulfate, or methyl sulfate anions, wherein the total concentration of the compounds according to group b) is 5% by weight or higher, calculated based on the total weight of composition A, wherein composition A comprises one or more quaternary ammonium surfactants according to the following structure as compounds according to group e): Where R 5 and R The 6 series is independently selected from C 1 to C 16 Alkyl or alkylene, wherein the limitation is at least R The 5 series is selected from C 8 to C 16 Alkyl or alkylene, R 7 and R The 8 series is independently selected from C 1 to C 4 alkyl or alkylene, and Y - It is a halogen, sulfate or methyl sulfate anion, and the total concentration of one or more compounds according to group e) is in the range of 0.5% to 10% by weight, calculated based on the total weight of composition A. A second objective of the present invention is a kit for dyeing keratin fibers, preferably human keratin fibers, and more preferably human hair, comprising: - composition A as defined above, - an aqueous acidic composition B having a pH in the range of 1 to 6 and, where appropriate, containing one or more oxidizing agents, preferably hydrogen peroxide, - a bleaching composition C, where appropriate. A third objective of the present invention is a ready-to-use composition having a pH in the range of 6 to 12, comprising composition A as defined above and composition B as defined above. A fourth objective of the present invention is a method for dyeing keratin fibers, preferably human keratin fibers, and more preferably human hair, comprising the following steps: i) mixing composition A as defined above with acidic aqueous composition B as defined above to produce a ready-to-use composition having a pH in the range of 6 to 12; ii) applying the ready-to-use composition to keratin fibers and allowing it to stand for a period of 1 to 60 minutes; iii) rinsing off the ready-to-use composition; and iv) washing and drying the keratin fibers with shampoo as appropriate.

Preferably, the pH of the ready-to-use composition in step i) is in the range of 6.5 to 11.5, more preferably in the range of 7 to 11. Preferably, the ready-to-use composition is placed on keratin fibers for a period of 2 to 45 minutes in step ii), more preferably for a period of 5 to 35 minutes. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention. Example surface 1. Prepare the following composition A: Composition B weight % Hydrogen peroxide 6.0 EDTA 0.5 Phosphoric acid supplemented to pH 2.5 Water supplemented to 100.0 Composition A of Table 1 and Composition B as above were mixed at a weight ratio of 1:1 to produce a ready-to-use composition having a pH of 7.0. Ready-to-use compositions have viscosities in the range of 1,500 mPas to 4,000 mPas, which were measured at atmospheric pressure at 5 rpm and 25°C using a Brookfield RV DVIII viscometer and shaft #3. Discussion of the Results The examples in Table 1 illustrate that the compositions of the present invention have a higher total score. Specifically, the dry hair sensation as well as the drops of ready-to-use type mixtures were rated much higher than those of the comparison compositions. means Preparation of Compositions Compounds according to group c) were dissolved in compounds according to group b), followed by the addition of other components. Finally, the alcohol-based composition was diluted with water. Hair Staining To prepare ready-to-use compositions, each of the compositions from Table 1 was mixed with the composition B having a pH of 2.5 shown above in a weight ratio of 1:1. 2 g of the resulting ready-to-use composition was applied to goat hair (2.5 g per bundle, 21 cm long) and allowed to stand at ambient temperature for 20 min. Subsequently rinse the hair with water and blow dry. Drop In order to prepare the ready-to-use type composition, each of the compositions from Table 1 was mixed with the composition B having a pH of 2.5 shown above in a weight ratio of 1:1. 2 g of the resulting ready-to-use type composition was applied to the forearm, and the dripping was monitored for 5 min. The evaluation asked five experts to rate the streaks of colored hair and the results on the forearm independently of each other. The experts were not informed whether they were in the processing group until they made their judgment. It is required to assign an integer value for each characteristic as listed in Table 1 . Grades in the range of 1 to 10 were given for wet and dry hair sensations. Grades from 1 to 5 were given for transparency, stability and drop. Higher numbers indicate optimal performance. The reported values ​​for each group were multiplicity values.
