This invention relates to alkaline hair lubricants based on mixtures of hydrogen peroxide and persulfate.

The use of hydrogen peroxide-containing compositions for lathering of hair is already known. By the addition of persulphates, the decolorizing effect of the hydro [ζ gene peroxide-containing compositions can be further enhanced.

T- ^ Since the natural color pigments of the hair which give the hair the red, or yellow tones, respectively, in the blending treatment are not affected as easily as the pigments which contribute to the brown or black tones, in the case of lace especially of dark hair. an undesirable red or yellow hue occurs.This disadvantage can be avoided by the use of blue dyes, which together with the yellow or red tint of the hair gives a brownish or platinum blonde color that many would like. In this way, the beauty of the hair with the blue dye can be completely problem-free with one separate dyeing treatment.

However, since the treatment in the form of a separate staining means an additional cost in terms of labor, time and expenses, efforts were made very early to eliminate the special staining treatment and to combine lace and toning in one treatment.

If only a moderate degree of bleaching is desired in the lace, a lace mixture may be used which contains only alkaline hydrogen peroxide without the addition of persulfate. In this case, a whole range of blue dyes can be incorporated easily without difficulty into the lace mass. The stability of most hair dye usual blue dyes is good enough that this lace mixture is not decomposed during the lace treatment.

Of course, the same opportunity to blend and tone in one treatment is also desired using a very vigorous blending mixture of hydrogen peroxide and persulfate. However, all experiments in this regard failed due to the lack of stability of blue dyes used so far for the hair dyeing purposes against the extremely strong oxidizing mixture of hydrogen peroxide and persulfate in alkaline environment.

Surprisingly, it has now been found that alkaline lubricants based on mixtures of hydrogen peroxide and persulfates which are characterized by a content of 2'-xnethyl-4 '- (N-ethyl-Nm-sulfobenzyl) -amino-4' - ( N-diethyl) -amino-2-methyl-N-ethyl-Nm-sulfobenzyl-fuchsonimonium (brilliant blue R 28032 ex. Cone., Color Index No. 42,835) and 1,5-di- (4'-methyl- 2'-sulfo = phenylamino) anthraquinone (acid color R 5283, Color Index no.

61 710) satisfactorily meets the requirements set.

Such a dye combination remains stable for a very long time in the extremely strong oxidizing alkaline mixture of hydrogen peroxide and persulfate, is well absorbed by the hair and thus proves to be extremely suitable for beautifying the hair by bleaching with a hydrogen peroxide persulfate mixture in one. treatment.

The amount of the two dyes brilliant blue R 28032 ex. conc. and acid color R 5283 in the dye mixture may vary within wide limits in the weight ratio of 1: 9 to 9: 1 depending on the desired tinting effect of the invention. The most favorable blend to achieve the desired effect has, according to the invention, been found to be a ratio of brilliant blue R 28032 ex. conc. for acid color R 5283 as 2: 1.

The amount of dye mixture to be used, in general according to the desired tinting effect according to the invention, is between 0.015 and 0.3% by weight, preferably 0.03 to 0.12% by weight, based on the blend mixture. Preferred amount ratios, especially when using the components brilliant blue R 28032 ex. conc. and acid color R 5283 in a 2: 1 ratio is 0.02: 0.01 to 0.08: 0.04% by weight, based on the lace blend.

As bleaching components, the blending compositions of the invention preferably contain hydrogen peroxide in an amount of from 1 to 10% by weight, preferably from 2 to 6 washings, based on the total blending composition. Instead of the hydrogen peroxide, the corresponding amount of a per-compound can be used which, when dissolved in water, releases hydrogen peroxide such as e.g. the water-soluble alkali metal oxides, 3-word alkaline talc are oxides, urea peroxide and melamine peroxide.

The amount of the additional incoming persulfates which act as bleaching agents, such as ammonium peroxide disulfate, potassium per oxide disulfate or sodium peroxide disulfate, is usually within the range of from 2 to 45 wt., Preferably 5-40 wt.%, Based on the total lace composition.

To ensure easy handling, thickeners are suitably added to the lace mixtures which give the products a creamy consistency. For this purpose, the usual products for this purpose can be used in amounts of 1-8% by weight, based on the total lace mixture, such as, e.g. thickeners ealcium carbonate, magnesium carbonate, talc, kaolin, bentonite, sodium metasilium 4

cat, carboxymethyl cellulose and higher fatty alcohols. In addition to the thickeners, wetting agents, solvents, earbonate or phosphate buffers may be added to the products to stabilize the pH, and fragrances in usual amounts.

The lace mixtures are preferably made alkaline with ammonia, but this can also be done by other basic reacting compounds. The pH of the mixtures is adjusted to values of approx. 8 to 11 and should not exceed the value of 12. The use is customary at temperatures between 10 and 40 ° C.

The following examples illustrate - the present invention '

Example 1

Lace cream based on a cream.

First, a cream is prepared from the following ingredients: cetylstearyl alcohol 11.0 parts by weight lauryl sulfate 12.0 "ammonium sulfate 1.0" brilliant blue R 28032 ex. conc. 0.06 11 acid color R 5283 0.03 "concentrated ammonia 14.0" perfume oil 1.0 "water 60.7"

For the preparation of the lace mixture, 50 g of the aforementioned cream is mixed with 50 g of a 6 g of hydrogen peroxide solution and 14 g of ammonium peroxide disulfate.

For lace, this lace blend is applied to dark blonde to black hair and the mixture is allowed to sit in the hair at room temperature for 30 minutes. Then the hair is washed with water and dried.

Of course, in addition to the lace, further treatments of the hair can be done. The bleached hair of the invention had no reddish or yellowish hue, but a very pleasing platinum blonde tone.

Example 2

Lace blend on the basis of a lace powder.

The ingredients listed below were carefully mixed into a persulfate-containing bleaching powder: magnesium oxide 40.0 parts by weight of magnesium arbonate 19.55 "potassium peroxide disulfate 20.0" ammonium peroxide disulfate 20.0 "brilliant blue R 28032 ex. cone. 0.3 "acid color R 5283 0.15"

For the preparation of the blend mixture, 1 part by weight of the powder is mixed with 3 parts by weight of a 6 µg hydrogen peroxide solution.

The use was carried out in a similar manner as in Example 1 and also gave a silver blonde hair.
