Abstract

Process for the treatment of keratin fibers, in particular human hair, in which an agent for coloring and / or lightening hair is applied to the hair and the treated hair, following application of the agent, for 1 to 60 minutes with UV radiation in the wavelength range of 200 Irradiated up to 600 nm leads to shorter exposure times and improved coloring and / or lightening results on the hair treated in this way.

Description

The cosmetic treatment of skin and hair is an important part of human body care. For example, human hair is today treated in a variety of ways with hair cosmetic preparations. These include, for example, the cleansing of hair with shampoos, the care and regeneration with rinses and cures and the bleaching, dyeing and shaping of the hair with dyes, tinting agents, waving agents and styling preparations. In this case, means for changing or nuancing the color of the head hair play a prominent role. Apart from the bleaching agents that cause an oxidative lightening of the hair by degradation of the natural hair dyes, so in the field of hair coloring essentially three types of hair dye are of importance:
For permanent, intensive colorations with corresponding fastness properties, so-called oxidation colorants are used. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components.

The Developer components form under the influence of oxidizing agents or of atmospheric oxygen with each other or under coupling with one or several coupler components, the actual dyes. The An oxidation are characterized by excellent, long-lasting staining results out. For natural looking colorations but usually a mix of a larger number be used by oxidation dye precursors; in many make continue to use direct dyes for shading. Assign the formed during the color training or directly used dyes significantly different fastnesses (eg. B. UV stability, Perspiration, Wash fastness etc.), it can become a recognizable one over time and therefore undesirable Color shift come. This phenomenon occurs increasingly, if the hairstyle hairs or hair zones of varying degrees of damage having. An example for are long hair, where the long time all sorts of environmental influences exposed hair tips are usually significantly more damaged as the relatively freshly grown hair zones.

For temporary dyeings become common dyeing or tinting agent used as dyeing Component so-called direct pullers included. This is it about dye molecules, which grow directly on the hair and no oxidative process to training need the color. Belongs to these dyes for example, that from ancient times to the coloring of body and hairs known henna. These dyes are against shampooing usually much more sensitive than oxidative stains, so that then much more quickly a much undesirable nuance shift or even a visible "discoloration" occurs.

Finally has in the most recent Time a novel dyeing process size Attention found. In this process, precursors of the natural Hair dye melanin applied to the hair; these form then in the context of oxidative processes in the hair natural analog dyes. In such processes, for example, 5,6-dihydroxyindoline as Dye precursor used. In, in particular multiple, application By means of 5,6-dihydroxyindoline it is possible to give people with graying Hair the natural Reproduce hair color. The coloration can be done with atmospheric oxygen take place as the sole oxidant, so that no further oxidizing agents resorted must become. In persons with original Medium-blond to brown hair, indoline can be the sole dye precursor be used. For the application in persons with originally red and in particular Dark to black hair color, on the other hand, can be satisfying Results frequently only by the concomitant use of other dye components, in particular special oxidation dye precursors can be achieved.

at an application of oxidants, the actual colorant is usually immediately before use by mixing the preparation of the Oxidizing agent with the preparation containing the dye precursors, produced. The oxidants used are predominantly aqueous hydrogen peroxide solutions.

at hair coloring - especially in hair coloring through the home application - step several problems. One problem lies in the exposure time the means that possible should be short to possible Prevent irritation and the application less time consuming to design. This is the coloring result through the shortened However, exposure time will not be affected.

Of the present invention was based on the object, a hair dyeing and / or to provide a brightening process, which differs from the prior art by advantages in terms of application (application time) and / or the effects achieved (intensity and brilliance of the colorations or brightening) lifts. In particular, dyeing effects should reinforced and / or treatment or Action times shortened become.

It it has now been found that it is beneficial, means of dyeing and / or lighten hair on the hair and that so treated hair before rinsing of the agent with UV radiation to irradiate.

One The first object of the present invention is a method for Treatment of keratinic fibers, especially human hair, in which a dyeing agent and / or lightening hair applied to the hair and that treated hair following applying the agent for 1 to 60 minutes with UV radiation in the wavelength range 200 to 600 nm is irradiated.

UV radiation (Ultraviolet radiation) are electromagnetic waves of the wavelength of about 380 to 10 nm or a frequency of about 790 THz to 30 PHz. The energy of a single light quantum is in the range of approx. 3.3 eV (380 nm) to about 124 eV (10 nm).

ultraviolet radiation is not visible. she counts however, to the group of optical wavelengths, which is why often the misleading Term "UV light" is encountered. UV radiation can be like light of other wavelengths or infrared radiation broken, reflected, transmitted, absorbed and diffracted.

By Fluorescence can indirectly make ultraviolet radiation visible become.

Below a wavelength of about 200 nm, the energy of a single ultraviolet light quantum is sufficient, Electrons from atoms or molecules to solve, i.e. to ionize them. As well as gamma and X-rays are called therefore short-wave ultraviolet radiation below about 200 nm than ionizing radiation.

in the inventive method a hair treatment agent is applied to the hair to be treated and subsequently irradiated with UV light. Because the head of the person being treated UV exposure is the usual precautionary measures when handling ultraviolet radiation. Especially Too long a period of irradiation should be avoided. Here are methods according to the invention preferred in which the treated hair following the Application of the agent 1 to 60 minutes, preferably 2 to 50 minutes, more preferably 5 to 40 minutes and especially 10 to 30 For minutes with UV radiation UV-A (400-320 nm) and / or UV-B (320-280 nm) and / or UV-C (280-200 nm) is irradiated.

Especially The irradiation is preferred in the context of the method according to the invention with UV-A radiation, because the shorter-wave Types of radiation, especially with prolonged irradiation health Can cause irritation. Particularly preferred is the use of UV radiation with wavelengths above of 350 nm, for example those with wavelengths of 365 nm, those with Wavelengths of 370-375 nm, those with wavelengths from 380-385 nm, those with wavelengths from 390-395 nm or such with a wavelength of 400 nm.

in the Connection to The radiation can be applied to the hair before the irradiation Means flushed out of the hair become. According to the invention preferred Methods are characterized in that the means for dyeing and / or Lightening of hair after irradiation is rinsed out of hair.

By the procedure according to the invention can reduce the exposure time of hair dyes and / or lightening agents (bleaching agents) with the same result across from the conventional one Application significantly shortened become. At comparable exposure times by the inventive method achieved significantly improved performance, among other things in more brilliant, intense colorations and / or lightening manifest.

in the inventive method becomes a dyeing agent and / or lightening hair.

conventional Hair Dye usually consist of at least one developer and at least a coupler substance and optionally contain direct dyes as a nuance. Coupler and developer components are also known as Oxidation dye precursors referred.

When Developer components are usually primary aromatic amines with another, in para or ortho position free or substituted hydroxy or amino group, Diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and its derivatives used.

Finally has another dyeing process size Attention found. In this process, precursors of the natural Hair dye melanin applied to the hair; these form then in the context of oxidative processes in the hair natural analog dyes. Such a method uses, for example, 5,6-dihydroxyindoline as a dye precursor. In, in particular multiple, application By means of 5,6-dihydroxyindoline it is possible to give people with graying Hair the natural Reproduce hair color.

For the application in persons with originally red and in particular Dark to black hair color, on the other hand, can be satisfying Results frequently only by the concomitant use of other dye components, in particular special oxidation dye precursors can be achieved. Also here we can then problems regarding the authenticity of the dyeings occur.

• A Verbindungen, die eine reaktive Carbonylgruppe enthalten mit Komponente
• B Verbindungen, ausgewählt aus (a) CH-aciden Verbindungen, (b) Verbindungen mit primärer oder sekundärer Aminogruppe oder Hydroxygruppe, ausgewählt aus primären oder sekundären aromatischen Aminen, stickstoffhaltigen heterozyklischen Verbindungen und aromatischen Hydroxyverbindungen, (c) Aminosäuren, (d) aus 2 bis 9 Aminosäuren aufgebauten Oligopeptiden

enthalten. Die entsprechende Färbemethode wird im Folgenden Oxofärbung genannt. Die resultierenden Färbungen besitzen teilweise Farbechtheiten auf der keratinhaltigen Faser, die mit denen der Oxidationsfärbung vergleichbar sind. Das mit der schonenden Oxofärbung erzielbare Nuancenspektrum ist sehr breit und die erhaltene Färbung weist oftmals eine akzeptable Brillanz und Farbtiefe auf. Die vorgenannten Komponenten A und B sind im allgemeinen selbst keine Farbstoffe, und eignen sich daher jede für sich genommen allein nicht zur Färbung keratinhaltiger Fasern. In Kombination bilden sie in einem nichtoxidativen Prozess Farbstoffe aus. Unter Verbindungen der Komponente B können allerdings auch entsprechende Oxidationsfarbstoffvorprodukte vom Entwickler- und/oder Kupplertyp mit oder ohne Einsatz eines Oxidationsmittels Verwendung finden. Somit läßt sich die Methode der Oxofärbung ohne weiteres mit dem oxidativen Färbesystem kombinieren.Another way to stain keratin-containing fibers is through the use of stains containing a combination of component

• A compounds containing a reactive carbonyl group with component
• B Compounds selected from (a) CH-acidic compounds, (b) compounds having primary or secondary amino group or hydroxy group selected from primary or secondary aromatic amines, nitrogen-containing heterocyclic compounds and aromatic hydroxy compounds, (c) amino acids, (d) from 2 up to 9 amino acids oligopeptides

contain. The corresponding dyeing method is referred to below as oxo dyeing. The resulting dyeings have partially color fastness on the keratin-containing fiber, which are comparable to those of the oxidation dyeing. The Nuancenspektrum achievable with the gentle oxo staining is very broad and the color obtained often has an acceptable brilliance and color depth. The aforementioned components A and B are generally not themselves dyes, and are therefore each alone not suitable for coloring keratin-containing fibers. In combination, they form dyes in a non-oxidative process. However, it is also possible to use corresponding developer and / or coupler-type oxidation dye precursors with or without the use of an oxidizing agent under compounds of component B. Thus, the oxo staining method can be readily combined with the oxidative staining system.

According to the invention preferred Means contain at least one oxidation dye precursor of Developer type and / or optionally at least one oxidation dye precursor of the coupler type.
