Definitions
- the present invention relates to agents for oxidative color change in the field of cosmetics, which are particularly suitable for lightening keratin fibers, in particular human hair.
- the oxidizing agents contained in bleaching agents are able to lighten the hair fiber through the oxidative destruction of the hair's own dye melanin.
- the use of hydrogen peroxide is sufficient - if necessary with the use of ammonia or other alkalizing agents - as the oxidizing agent alone; to achieve a stronger bleaching effect, a mixture of hydrogen peroxide and peroxodisulfate salts and / or peroxomonosulfate salts is usually used.
- complexing agents for oxidative changes in the color of keratin fibers.
- the complexing agents should, among other things, prevent the decomposition of hydrogen by metal ions accumulated in the hair fibers.
- EP 1714634 A1 describes a hair treatment kit for coloring human hair, comprising a first compartment, which contains a complexing agent, and a second compartment, which contains means for coloring.
- a complexing agent is intended to prevent undesirable reactions on and with hair that lead to undesired heating.
- HEDP etidronic acid
- EDTA ethylenediamine tetraacetate
- Both HEDP and EDTA stabilize hydrogen peroxide in an effective way and complex existing metal ions so effectively that an undesirable temperature increase occurring during use is virtually completely avoided.
- the major disadvantage of HEDP and EDTA is their poor biodegradability. In recent times in particular, users have been paying increasing attention to the ecological profile of the cosmetic products they use. Above all, the user prefers cosmetics that are as sustainable as possible with biodegradable ingredients.
- the object of the present invention to find bleaching agents with biodegradable complexing agents which, with regard to their bleaching performance, are at least comparable, preferably even better, with the bleaching or lightening agents known from the prior art. Furthermore, the bleaching agents should have a sufficiently high stability and should not overheat even when used on hair with a higher metal or heavy metal content. In addition, the hair damage should be reduced when using the complexing agents in lightening or bleaching agents.
- a lightening or bleaching agent which, in addition to at least one oxidizing agent (a), also at least one special complexing agent (b) of a certain formula (I) and contains a radical scavenger (c).

- the lighter coloring of the hair is brought about by the oxidizing agent or agents present in the agent.

- the application mixture obtained in this way was applied to the locks of hair, left there for 45 minutes and then rinsed out again with water. The hair strands were then colorimetrically measured again.
- Strands with a high metal content were used to measure the temperatures occurring during bleaching.
- strands of hair were treated as follows: Strands of hair (Kerling, Euronaturhaar white, 6-0) were pre-shampooed and then pre-bleached once with a commercially available bleaching agent. The pre-bleaching was done to increase the copper absorption in the hair. The strand pre-bleached in this way was doped with copper:

- the hair strands lightened under point 3 were used to measure the hair damage.
- the hair damage to the hair lightened as described above was determined by means of quantitative NIR spectroscopy.
- the spectra were recorded with an MPA TM FT- NIR spectrometer from Bruker Optik GmbH.
- the infrared range covers the wave number range from 12500 cnr 1 to 4000 cnr 1 and is characteristic for overtone and combination vibrations of, for example, CH, OH and NH groups.
- the measurement of the samples was carried out with the penetration sphere module at six different sample positions in diffuse reflection.
- the wavenumber range from 7300 cm 1 to 4020 cm 1 was selected for the analysis of the measured NIR spectra.
- the NIR spectra of cystine show characteristic absorption bands in the wavenumber range from 6200 cm 1 to 5500 cm 1. If the hair changes due to greater damage (ie if the cysteic acid content in the hair increases), this affects the bands characteristic of cysteic acid at 5020 cm 1 to 4020 cm 1 in the NIR spectrum. The quantitative evaluation of the NIR spectra was computer-aided.
