The present invention relates to improved hydrogen peroxide persulfate-containing alkaline bleaching compositions containing a direct mixture of blue dyes.

The use of hydrogen peroxide-containing preparations for hair bleaching is well known. By adding persulphates, the bleaching effect of other hydrogen peroxide preparations can be considerably increased.

Because the natural color pigments in the hair, which give the hair red or yellow tones, do not break down in bleaching as easily as the pigments corresponding to brown or black tones, especially after bleaching dark hair, an unwanted red or yellow hue may remain. An attempt can be made to prevent this disadvantage by using blue dyes which, with a yellow or red hue of the hair, give a much more brownish or platinum-colored color worth pursuing. The hair can thus be beautified completely without any problems with a blue dye with a separate dye.

However, since treatment with a separate dyeing method requires an additional 2,66292 labor, time, and money, attempts have long been made to eliminate this separate dyeing and perform bleaching and tinting in a single operation.

If it is desired to obtain a medium bleach degree of bleaching, a bleaching mixture containing only alkaline hydrogen peroxide without persulfate can be used. In this case, a whole range of direct-acting blue dyes can be easily processed in their bleaching composition. In the dyeing of most hair, the stability of conventional blue dyes is so great that this bleaching mixture does not destroy them during bleaching.

The same possibility of bleaching and tinting in one step is, of course, also desirable when a very strong bleaching mixture of hydrogen peroxide and persulfate is used. However, all the effort seen in this regard has fallen to the instability of the dyes used so far for coloring hair in a very strongly oxidizing mixture of hydrogen peroxide and persulfate in an alkaline environment.

It has now surprisingly been found that alkaline bleach mixtures based on mixtures of hydrogen peroxide and persulphate containing (2'-methyl-4 '- (N-ethyl-Nm-sulfobenzyl) -amino-4 "- (N-diethyl) -amino- 2-methyl-N-ethyl-Nm-sulfobenzyl-fuxonium ammonium (Brillant-blau R 28032 ex.conc., Color-Index No. 42735) and (1,5-di- (4'-methyl-2'-sulfophenylamino) - anthraquinone (Fliederfarbe R 5283, Color-Index No. 61710) and that they contain Brillantblau R 28032 ex.conc and Fliederfarbe R 5283 in a weight ratio of 1: 9 to 9: 1.

The mixture with Brtillautblau R 28032 ex.conc has proven to be the best mixture with the most pleasant effect. the color ratio of Fliederfarbe R 5283 to color is 2: 1.

Such a dye combination remains stable for a long time in a very strongly oxidizing alkaline mixture of hydrogen peroxide and persulfate, has a good effect on the hair and is very well suited for beautifying hair by bleaching with a hydrogen peroxide-persulfate mixture in one operation.

The amount of dye combination used generally depends on the desired tinting effect, being between 0.015 and 0.3% by weight based on the bleaching mixture. In the best proportions, especially when used as components Brillantblau R 28032 ex.conc. color and Bliederfarbe I 66292 R 5283 color in a ratio of 2: 1, is considered to be 0.02: 0.01 to 0.08: 0.04% by weight of the bleaching mixture.

As bleaching components, the bleaching compositions according to the invention preferably contain from 1 to 10% by weight of hydrogen peroxide, preferably from 2 to 6% by weight, based on the total bleaching mixture. Instead of hydrogen peroxide, a corresponding amount of basic compounds can also be used which, when dissolved in water, release hydrogen peroxide, such as water-soluble alkali metal peroxides, alkaline earth metal peroxides, urea peroxide, melamine perhydrate and others.

The amount of persulphates such as ammonium peroxide sulphate, potassium peroxide sulphate or sodium peroxide sulphate still present in the mixtures as bleaching enhancers generally ranges from 2 to 45% by weight, preferably from 5 to 40% by weight, based on the total bleach mixture.

To make the treatment as effortless as possible, thickeners are added to the bleaching compositions as appropriate to give the products a creamy consistency.

In this case, products hitherto normally used for this purpose, such as calcium carbonate, magnesium carbonate, talc, kaolin, bentonite, sodium metasilicate, carboxymethylcellulose, higher fatty alcohols, based on 1 to 8% by weight of the total bleaching mixture, can be used. In addition to thickeners, the usual amounts of wetting agents, solvents, carbonate or phosphate buffers to stabilize the pH and fragrances may be added to the products.

The adjustment of the bleaching mixture to alkali is best performed with ammonia, but it can also be done with other base-reactive compounds. The pH of the mixtures is adjusted to about 8-11, the value of 12 should not be exceeded. The operation is carried out in the usual way at temperatures between 10 and 40 ° C.

The following examples further illustrate the scope of the invention without, however, limiting the invention thereto.

4,66292

Examples 1) Cream-based bleaching mixture

First, an ointment is made from the following ingredients:

Cetyl stearyl alcohol 11.0 parts by weight

Lauryl sulphate 12.0 "

Ammonium sulphate 1.0 "

Brillantblau R 28032 ex.conc. 0.06 "

Fliederfarbe R 5283 0.03

Ammonia, conc. 14.0 "

Perfume oil 1.0 "

Water 60.7 *

To prepare the bleaching mixture, 50 g of said ointment are mixed with 50 g of a 6% hydrogen peroxide solution and 14 g of ammonium peroxide sulfate.

This bleach mixture is applied to dark light black hair for bleaching and allowed to act at room temperature for 30 minutes. It is then washed with water and dried. After bleaching, the hair can, of course, be further processed. The bleached hair according to the invention does not have a red or yellow tinge, but a very pleasant platinum light shade.

2. Bleaching mixture based on bleaching powder

The successively added components are mixed into a persulfate-containing bleaching powder.

Magnesium oxide 40.0 parts by weight
