Method of coloring hair in which the depth of color is gradually increased in successive treatments

The invention relates to a method for dyeing human hair, are achieved in the progressively deeper by successive treatments dyes, until the desired shade achieved, and this sound can then be obtained by wei tere treatments at appropriate intervals.

In the past, human hair was colored by means of water-soluble compounds of heavy metals, for example Ni or Pb, together with reagents which, with the metal compound , result in a strongly colored, water-insoluble derivative, for example pyrogallol or sulfur compounds.

In a more adaptable dyeing process, from which the invention is based, oxidizable primary aromatic amines, especially diamines, and substitution products thereof, are usually

709849/0957

borrowed together with aminophenols, mixed with an oxidizing agent

Coupling components, such as a polyhydric phenol, for example resorcinol, ■ -i; Pyrogallol or the like. As an oxidizing agent: When dyeing hair, atmospheric oxygen alone can serve; \) i, however, is the use of HPOP or its derivatives forthcoming \\: Trains t, because then the reaction takes place more quickly and easily exceeded can be monitored '.

-f ·. Women generally prefer a staining process in which

• 1ϊ the desired color achieved with a single treatment

will. Men, on the other hand, are less likely to have their hair dyed in such a way that

u all the staining is done by a single treatment as it

} find this embarrassing. There is already one on the market

j Number of preparations with which, through repeated use in

\ ii'- certain time intervals the color gradually changed and

! ' deeper and the ultimately desired color through more, less

ρ frequent application can be obtained. In these preparations

709849/0957

is usually a compound of a heavy metal and a reagent that reacts with the metal to form a dark colored sulfide can form, contain. Compared to the oxidizing dyes, however, there is less variety that can be achieved with these preparations of staining can be achieved.

It is already known to gradually apply an oxidizing dye mixture to hair gradually at certain time intervals to be colored darker. It is also known to adjust the depth of the hue by varying the concentration of the dye to modify. The depth of the hue has also been increased by increasing the duration of the treatment, and it was known when using a trihydric phenol as a coloring agent together with an iodate, periodate or persulfate as an oxidizing agent to increase the depth of the hue produced by increasing the concentration of the oxidizing agent, wherein Oxidant and dye were used in the same or in separate solutions.

However, it was not known to be in use

aromatic primary amines and aminophenols as oxidation dyes for hair, the depth of the shade is increased by varying the proportion or concentration of the oxidizing agent change.

The object of the invention is a method for coloring hair with oxidative dyes, in which by at certain time intervals successive treatments first a certain light color and then gradually deeper tones are produced « until the desired color is achieved, which is then achieved by further applications of the last composition used at longer intervals can be obtained.

709849/0957

Another object of the invention is such a method in which the treatments are easily done by the person whose hair is colored and can be done in a short time of the order of five (5) minutes.

The object of the invention is also a hair coloring process, in which the depth of the hue, which is produced in subsequent treatments after an initial treatment, is thereby controlled can be that the amount of oxidizing agent added to a practically constant amount of dye used for each treatment is increased starting from an approximately stoichiometric amount for the first treatment.

According to the invention, a dye solution comprising a mixture of oxidizing dyes including, for example, p-phenylenediamine, p-tolylenediamine, p-aminophenol, 2,4-diaminoanisole and p-methylaminophenol, usually with a coupling component such as resorcinol, and an aqueous carrier, which contains surfactants conventionally used in shampoos, such as sodium lauryl sulfate, sodium lauryl polyethylene glycol ether sulfate, N-lauroyl diethanolamine and the sodium salt of ethylenediaminetetraacetic acid, as well as alkaline reagents such as borax, morpholine and sodium sulfite for adjusting the pH of the preparation. A perfume can also be included. The concentration of the coloring mixture, including the coupling component such as resorcinol, is expediently 0.5 to 8% by weight . The pH is preferably adjusted to 8-10. A solution of an oxidizing agent, in particular H ₂ O ₂ or an equivalent solution of H ₂ Op derivatives, such as urea peroxide, perborate or percarbonate, persulfate or periodate, is used together with such a dye solution.

709849/0957

In order to dye the hair first in a certain light tone and then one after the other in deeper tones , a practically constant amount of the dye solution, which is sufficient to evenly moisten the hair of the head, is used for successive treatments with one for the subsequent treatment ( For example, a total of 3 treatments) increased amounts of the oxidizing agent solution mixed, the last treatment producing the desired or desired color tone . In any case, after applying the mixture of dye and oxidizing agent to the hair, the color can develop within a certain time which is the same for each treatment , for example 5, 10 or 15 minutes . Then the preparation is rinsed off the hair with water. After the desired shade has been achieved, it is obtained by reapplying the mixture used for the last treatment for the deepening of the clay at such time intervals that the hair regrowth is colored in the desired shade .

The method according to the invention can be used easily and without professional help, because for each treatment only a certain, constant amount of dye solution is measured, mixed with an amount of oxidizing agent solution to be measured in the same way, and the resulting mixture of dye solution and oxidizing agent is applied to the hair apply, wait a certain time, for example 5 minutes, and rinse the remaining mixture off the hair, the amounts of oxidant solution in successive treatments after the first treatment are advantageously simple multiples of the amount used for the first treatment.

The following examples illustrate the invention. Figures in parts and percent relate to weight.

These dye solutions have a pH of 9.5, which allows for decomposition favored by HO and its peroxy derivatives.

The oxidizing agent used for the above dye solutions is 6% (ie 20% by volume) H ₃ O ₂ . However, an aqueous solution of an equivalent amount of urea peroxide, sodium perborate or sodium percarbonate can also be used and, if desired, some of the water can be replaced by propylene glycol in order to facilitate the dissolution.

For the application, 30 cnr dye solution A is required for the first treatment mixed with 2.5 cm of oxidant solution. The mixture is applied to the hair and for 5 minutes, i.e. a very short time compared to conventional dyeing processes, allowed to act. Then the hair is rinsed. The treatment results in a barely noticeable brownish color. After a desired, time to be determined by the consumer, for example 1 week, a second treatment is carried out for the Use 5 cnr of oxidizing solution with 30 cm of dye solution. After an exposure time of 5 minutes, the hair is rinsed, a light brown intermediate shade is obtained. Again, after a desired time of, for example, 1 week, a occurs third treatment using 10 cm of oxidant solution and 30 cnr dye solution. After 5 minutes of exposure and then Rinsing will get the light brown shade ultimately sought. This one can be obtained by taking the third one Treatment repeated at suitable time intervals of, for example, about 2 to 8 weeks each, in order to regrow hair in the desired area To color clay.

Appropriate treatments using the dye solution B result in a light brown tone first, then a dark

The dye solutions of the examples are used for coloring hair 2 and 3 in essentially the same manner as in Example 1 described, applied.

The amount of oxidizing agent used in the first treatments of the above examples should be about 0.5 to 2 times the amount required to oxidize the aromatic primary amino groups and aminophenols in the components of the dye solution is required. This amount of oxidizer was referred to above as "about stoichiometric" to indicate that they, compared with the amount required in known processes » is very small. The amount of oxidant for the second treatment in the above examples should be about 1.0 to 4 times that amount of oxygen necessary for the oxidation of the primary aromatic amino groups and aminophenols in the dye solution is required to deliver. In the third treatment and the subsequent treatments to maintain the color according to the examples should the amount of oxidizing agent about 2 to 10 times that amount of oxygen that is required to carry the aromatic primary amino groups and aminophenols in the used To oxidize dye solution, deliver.

In the dye solutions of the above examples, the concentration of surfactants is expediently between 10 and 25 #, that of the components used to adjust the pH between 2 and 10 # and that of the aromatic compounds with aromatic primary amino groups and aminophenols (with the coupling component or components) between 0.5 and 8%.

As the examples show, the amounts of oxidizing agent in the further treatment taking place after the first treatment

709849/0957

actions can be integral multiples of the set used in the first treatment , in particular multiples that form a geometric series (1,2,4) or simple multiples (1,2,3,4) . A geometric series of multiples is preferred, since it is thereby achieved that the hair becomes darker in a practically linear sequence until the desired tone is achieved. In any case , the development time for each treatment of the sequence is practically constant, ie it is, for example, 5, 10 or 15 minutes.

Oxidizable primary aromatic amines and aminophenols, which can be used in the dye solutions as such or in the form of their water-soluble salts, for example the sulfates, hydrochlorides or acetates, are for example:
