Description

"Colorful Salts of Amino Acids and Oligopeptides as Protective Ingredients in Hair Treatments"

The present invention relates to hair treatment compositions containing Bunte salts of amino acids and specific oligopeptides or peptides. These hair treatment compositions are particularly suitable for gentle bleaching or whitening hair dyeing. Another object of the invention is a kit containing at least two separately prepared preparations. The first preparation is the aforesaid hair treatment agent, and the second preparation is an oxidizing agent preparation containing at least one oxidizing agent. A third object of the present invention is a process for the oxidative dyeing and / or whitening of hair, in which the preparations of the kit - either sequentially or as a mixture - applied to the keratin fibers and the hair is washed.

The change in the color of the hair represents an important area of modern cosmetics and allows the adaptation of the appearance of the hair both to current fashion trends as well as to individual wishes of the individual. Brightening one's own hair color has always been the desire of many consumers, as a blonde hair color is considered attractive and fashionable in terms of desirable. For this purpose, various Blondiermittel with different Blondierleistung are available in the market. The oxidants contained in these products are able to lighten the hair fiber by the oxidative destruction of the hair dye melanin. For a moderate blonding effect, the use of hydrogen peroxide - optionally with the use of ammonia or other alkalizing agents - as the oxidant alone, for the achievement of a stronger Blondiereffektes usually a mixture of hydrogen peroxide and Peroxodisulfatsalzen and / or Peroxomonosulfatsalzen is used.

However, the lightening is also accompanied by damage to the hair, as not only the dyes of the hair, but also the other structural components of the hair are oxidatively damaged. Depending on the severity of the degree of damage, this ranges from rough, brittle and difficult to comb hair over a reduced resistance and tear resistance of the hair to hair breakage. The greater the amount of hydrogen peroxide used and, where appropriate, the peroxodisulfates, the greater the damage is usually caused on the keratin fiber.

To avoid or minimize the damage caused by the oxidative hair damage is constantly looking for new ingredients and active ingredients. Corresponding active ingredients can be used both as pretreatment agent before the oxidative dyeing or whitening process, during the oxidative treatment - as an additive to the oxidative dyeing or bleaching agents - or as a post-treatment agent. Of particular interest in this case is finding active substances which can be used both as pre- and post-treatment agents, but which are also added to the oxidative bleaching or coloring agent and in this way already minimize the damage during the oxidative hair treatment process or prevent.

It was therefore the object of the present application to provide novel hair treatment compositions which minimize or prevent hair damage caused by an oxidative hair treatment process. These agents should be universally applicable, i. they should be suitable both for use as pre-treatment and / or as a post-treatment agent and moreover can be added directly from the oxidative bleach or colorant. Since the agents are also to be used as an additive to an already existing bleaching or dyeing product, the finding of active ingredients which already have a good action even with particularly small amounts used is of very particular interest.

Various substances are known from the prior art, to which a nourishing effect is attributed. These usually attach themselves to the hair surface and smooth in this way the roughened or damaged cuticle. In the short term, a reduction in hair damage can be achieved with these compounds. However, if the consumer washes his hair, these substances are rinsed off the surface of the hair again. For this reason, the use of substances that exert the care effect only by the superficial deposition on the cuticle, the achievement of a long-term care effect is not possible.

Another object of the present application was therefore also the provision of hair treatment compositions which have a long-term care effect and their care effect is present even after repeated washes.

In an unpredictable manner, it has now been found that the use of Bunte salts of specific amino acids, oligopeptides and peptides in hair treatment compositions leads to a particularly long-lasting care effect. The hair treatment compositions containing these Bunte salts could be used both as a pretreatment agent and as a post-treatment agent. It was particularly surprising that even when added to oxidative bleaching or coloring agents, the compositions showed a strong action even in very small amounts-even if these bleaching products containing oxidatively very aggressive persulfates were added A first subject of the present invention is therefore a hair treatment composition containing in a cosmetic carrier

Finally, the radical R3 can also stand for a (sulfosulfanyl) methyl group, this is a Bunte salt structure of the formula HO-S (O 2) -S-CH 2 -.

Depending on the pH of the hair treatment agent, the Bunte salt structure of the formula HO-S (O 2) -S-CH 2 - may also be present in its deprotonated form.

The radical M2 represents a hydrogen atom, one equivalent of a monovalent or polyvalent cation or an ammonium ion (NH4) ⁺ .

As preferred equivalents of a mono- or polyvalent cation, in particular the cations of sodium and potassium (Na ⁺ or K ⁺ ) or also magnesium or calcium (1/2 Mg 2+ or Ca 2+) can be mentioned.

If M2 is a hydrogen atom, then the moiety -OM2 is the grouping -OH. If M2 stands for a sodium cation, then the grouping -OM2 is the grouping -ONa. If M2 stands for a potassium cation, then the grouping -OM2 is the grouping -OK. If M2 stands for an ammonium ion, then the grouping -OM2 is the grouping -0 (NH4). The compounds of the formula (I) according to the invention are either the Bunte salt of the amino acid cysteine, the Bunte salts of oligo-peptides or else the Bunte salts of peptides.

When R1 is hydrogen and M1 is a group -OM2, then the compound of formula (I) is the Bunte salt of the amino acid cysteine. In this case, the compound of formula (I) is the compound of formula (IA),

where M2 is again defined as previously described.

If the compound of formula (IA) is in the form of its free acid, it is 2-amino-3- (sulfosulfanyl) propanoic acid. This substance is commercially available.

It has been found that the use of the compound of the formula (IA) in hair treatment compositions already at particularly low levels of use leads to a particularly effective reduction of hair damage, which is still present even after repeated hair washing. Therefore, the use of compounds of the formula (IA) in hair treatment compositions is very particularly preferred.

In a very particularly preferred embodiment, a hair treatment agent according to the invention, characterized in that it contains at least one compound of formula (I), wherein

R1 is a hydrogen atom and

M1 stands for a grouping -OM2.

When a compound of formula (IA) is used, it is preferably the use of this specific compound. However, if the colored salts of oligopeptides are used as compounds of the formula (I), the hair treatment composition according to the invention may also comprise a plurality of compounds of the formula (I) as a mixture of different oligopeptides. These oligopeptides are defined by their mean molecular weight. The average molecular weight M _{w of} the at least one oligopeptide of the formula (I) can be determined, for example, by gel permeation chromatography (GPC) using polystyrene as an internal standard in accordance with DIN 55672-3.

Depending on how many structural elements of the formula (II) and / or (III) are contained in the compound of the formula (I), and depending on the nature of these amino acids, the molecular weight of the compound of the formula (I) used according to the invention may vary. It is particularly preferred according to the invention if the compound of the formula (I) is an oligopeptide which has a molecular weight M _{w of} from 200 to 2,000 Da, preferably from 250 to 1,500 Da, preferably from 300 to 1,200 Da, in particular from 400 to 800 Da.

The term "oligopeptide" in the context of the present invention is understood as meaning condensation products of amino acids which have the abovementioned molecular weights.

In a very particularly preferred embodiment, a hair treatment composition according to the invention is characterized in that it contains at least one compound of formula (I) having a molecular weight M _{w of} from 200 to 2,000 Da (daltons), preferably from 250 to 1,500 Da, preferably from 300 to 1,200 Da, in particular from 400 to 800 Da.

If a mixture of oligomers is used in the hair treatment composition according to the invention, these mixtures can be defined by their average molecular weight.

In this case, a preferred hair treatment agent according to the invention is characterized in that it contains at least one mixture of compounds of formula (I) having an average molecular weight M _{w of} from 200 to 2,000 Da, preferably from 250 to 1,500 Da, preferably from 300 to 1,200 Da , in particular from 400 to 800 Da.

Furthermore, it has been found that the repair effect possessed by the compounds of the formula (I) also depends on the repetition indexes x and y. As described above, it is most preferred for x to be an integer from 1 to 10 and y to be an integer from 1 to 10.

In a further very particularly preferred embodiment, a hair treatment composition according to the invention is characterized in that it contains at least one compound of formula (I), wherein

R1 represents a structural element of the formula (II), and

M1 stands for a structural element of the formula (III), and x stands for an integer from 1 to 10 and

y is an integer from 1 to 10.

In addition to the molecular weight of the compound of the formula (I), the proportion of the Bunte salt units contained in the compound of the formula (I) also has a decisive influence on the effectiveness of the "repair effect" of the compounds.

Compounds with at least one Bunte salt unit - as it is present for example in the compound of formula (Ia) - are very effective, especially when they are used as a monomeric compound. Oligopeptides having at least one Bunte salt unit are particularly effective when they have a low molecular weight of up to 1200, especially 800 daltons.

When using oligopeptides, however, it is of very particular advantage if the compound of the formula (I) has at least two, preferably at least three Bunte salt units.
