Abstract

Agent comprises at least one oxidation dyestuff initial product in a cosmetic carrier and at least one vegetable fatty acid triglyceride that has an iodine value of at least 150 (AOAC 26.020-26.021 method). An independent claim is included for kit of parts comprising at least two separately assembled containers, where a container (a) contains a color changing composition, and another container (b) contains an oxidant containing at least one chemical oxidizing agent, preferably hydrogen peroxide.

Description

object The invention is an oxidative color change agent of keratinic fibers, which is in a cosmetic carrier in addition to at least one oxidation dye precursor a vegetable oil in the form of a triglyceride with a high content of unsaturated Contains fatty acids. The invention Agents are particularly suitable for the reduction of hair damage and to improve the hair surface in the oxidative Coloring on human hair. In addition, concerns The invention relates to the use of the hair damage reducing agent and to improve the hair surface. The usage such agent is further advantageous in color elevation to the Keratin fiber in oxidative hair coloring.

The Changing the shape and color of the hair represents an important one The field of modern cosmetics dar. This can change the appearance the hair both current fashion trends and the individual wishes of the individual person to be adjusted. These agents should be used in addition to the desired dyeing and mold performance minimizing damage on the hair. To provide color-changing cosmetic preparations, in particular for the skin or keratin-containing Fibers such as human hair, the expert knows depending on the requirements of the coloring various dyeing systems.

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 under the influence of oxidizing agents or of atmospheric oxygen among one another form the actual dyes. Draw the oxidation colorants excellent, long-lasting staining results out. For temporary dyeings are usually Dyeing or toning agents used as coloring Component contain so-called substantive dyes. in this connection These are dye molecules that are directly on the Raise substrate and no oxidative process for training need the color. Finally, another one Dyeing process found great attention, in which Precursors of the natural hair dye melanin on the Substrate, e.g. As hair, are applied, which then in the frame form oxidative processes in the hair nature-analogous dyes.

Should Substrates are lightened or even bleached, which become the substrate coloring dyes usually oxidative using appropriate Oxidizing agents, such as hydrogen peroxide, decolorized.

oxidative Colorants usually contain hydrogen peroxide as Oxidant. This leads beside the desired one cosmetic effect to oxidative damage to the hair surface. Also usually leads in such means Basic pH adjusted to the structure of the hair oxidatively damaged. Depending on the expression of the Degree of damage, this ranges from rough, brittle and more difficult combed hair over a diminished one Resistance and tear resistance of the hair to hair breakage. The larger the amount of used hydrogen peroxide, the stronger damage are usually caused on the keratin fiber. Especially Split or even breakage of the fiber is the highest of the consumer unwanted side effects of a bleaching, the especially with repeated repetition of the oxidative dyeing process may occur. It is therefore particularly desirable To provide colorants, in addition to a good dyeing performance make a positive contribution to improving the fiber structure and thus simultaneously act as a care or conditioner. Thus, the otherwise often required additional care after treatment is dispensed with, both in terms of application comfort as additional Treatment step as well as in terms of packaging economics has disadvantages.

In In the past, tests proved to be commercially available To incorporate caring substances in dyes, often as inadequate and unsuccessful, as usual care substances for keratinic fibers especially among the harsh ones oxidative staining conditions lack of stability own and show only limited effect. It exists Thus, a great need for improvement for such less damaging or nourishing dyes.

Farther can also reduce the amount of application required Dyeing agents lead to an improvement in the fiber load. It is therefore not only from an economic point of view desirable, colorant with an improved Dyeing properties, in particular an improved Paint lift on the keratin fiber to provide.

task The present invention is therefore the provision of cosmetic Agent for the color change of keratinic fibers, which is the compensate for the disadvantages described above and the one reduced Have hair damage. Such a reduced hair damage can be for example on the hair surface by reducing hair breakage or split ends or improvement prove the combing. Furthermore, an improvement the color lift on the fiber is an object of the present invention.

In unpredictable way could now be found that color-changing Means, in addition to an oxidation dye precursor as a color-changing Component at least one fatty acid triglyceride with a contain high levels of unsaturated fatty acids, avoid the above mentioned disadvantages. Due to the caring Effect of using the agent according to the invention the hair damage can be significantly improved thereby.

One The first object of the invention is therefore an agent for oxidative Color change of keratinic fibers, in particular human hair, which is in a cosmetic carrier contains at least one oxidation dye precursor and characterized in that the agent additionally contains at least one vegetable fatty acid triglyceride, which has an iodine value of at least 150 (method AOAC 26.020-26.021) has.

Under keratin fibers or keratin fibers are furs, wool, To understand feathers and especially human hair. Although the agents according to the invention primarily for dyeing are suitable for keratin fibers, is in principle a use also in other areas nothing contrary.

The agents according to the invention contain the active ingredients in a cosmetic carrier. This cosmetic carrier is watery, alcoholic or watery-alcoholic. For the purpose of hair coloring such carriers are, for example, creams, emulsions, gels or surfactant-containing foaming solutions, such as shampoos, foam aerosols or other preparations which are suitable for use on the hair. For the purposes of the present invention, aqueous-alcoholic carriers are water-containing compositions containing 3 to 70% by weight of a C ₁ -C ₄ -alcohol, based on the total weight of the application mixture, in particular ethanol or isopropanol. For the purposes of the invention, an aqueous carrier contains at least 30% by weight, in particular at least 50% by weight, of water, based on the total weight of the application mixture.

When first essential ingredient contains the inventive Means at least one vegetable fatty acid triglyceride, which has an iodine value of at least 150 (method AOAC 26.020-26.021) has.

Under a fatty acid triglyceride is according to the invention a Ester of triol glycerin with three equivalents of fatty acid to understand. It can be both structurally same as different Fatty acids in a molecule triglyceride at the Ester formation involved.

The iodine value is a measure of the degree of unsaturation of a compound and indicates the amount of a halogen compound which can be taken up by a certain amount of sample by addition to CC double or triple bonds. The determination of the iodine value is known to the person skilled in the art and is determined by standardized analysis methods, such as L 13.00-10 (ent speaks DIN EN ISO 3961: 1999-08 ) or method AOAC 26.020-26.021. A high iodine value therefore represents a high proportion of unsaturated constituents in a compound.

According to the invention preferred Agents have an iodine value of at least 155, preferably at least 160 and more preferably between 160 and 250.

natural, and therefore also vegetable, fatty acid triglycerides are common Mixtures of esters of glycerol with different fatty acids Typically, such fatty acid triglycerides mixed glycerides of saturated and unsaturated Fatty acids.

The vegetable fatty acid triglycerides according to the invention are characterized by the fact that they have a high content of unsaturated Contain fatty acids.
