Abstract

The invention relates to agents for color change keratinischer fibers, in a cosmetically acceptable carrier - at least one natural dye, - at least one polysaccharide having at least one repeating monomer unit which carries at least one anionic group, and - at least one optionally hydrogenated vegetable oil contain. The compositions according to the invention are sufficiently stable and lead to satisfactory colorations, which can also be intense by multiple application, that is to say by color composition. The dyes allow dyeing while maintaining the fibers, which can be through an increased gloss, a pleasant smoothness (surface smoothing) and strengthening the fibers noticeable.

Description

The The present application relates to color-modifying agents for keratinic fibers containing at least one natural dye, at least a specific polysaccharide and at least one optionally hydrogenated vegetable oil as well as hair treatment procedures with such means.

Human Hair is used today in a variety of ways with hair cosmetics Treated preparations. These include cleaning hair with shampoos, care and regeneration with rinses and cures, as well as the bleaching, dyeing and shaping of the Hair with coloring, tinting preparations, world-wide and styling preparations. There are funds for change or nuancing the color of the head hair a prominent role.

For permanent, intense colorations with corresponding fastness properties so-called oxidation dyes are used. Such Colorants usually contain oxidation dye precursors, see above said developer components and coupler components. The developer components form under the influence of oxidizing agents or atmospheric oxygen with each other or under coupling with one or more coupler components the actual dyes. The oxidation colorants are characterized by excellent, long-lasting staining results out. For natural-looking dyeings usually needs a mix of a larger one Number of oxidation dye precursors are used; in many Cases continue to be substantive dyes for shading used.

For temporary stains become common Dyeing or toning agents used as coloring Component so-called Direktzieher included. This is it They are dye molecules that grow directly on the hair and do not need an oxidative process to form the paint. For example, these dyes already belong from antiquity to the coloring of body and hair known henna. These dyes are against shampooing usually sensitive, so that often undesirable Shade shift or even a visible "discoloration" occur can.

Finally, recently, a novel dyeing process has received much attention. In this process, precursors of the natural hair dye melanin are applied to the hair; These then form naturally-analogous dyes in the course of oxidative processes in the hair. Such a process with 5,6-dihydroxyindoline as a dye precursor has been described in US Pat EP-B1-530 229 described. In particular, multiple use of agents with 5,6-dihydroxyindoline, it is possible to reproduce natural hair color to people with graying hair. The coloration can be done with atmospheric oxygen as the sole oxidant, so that no further oxidizing agents must be used. In individuals with originally medium blond to brown hair, the indoline can be used as the sole dye precursor. Nevertheless, this novel method has the disadvantage that, although natural nuances can be achieved well, but fashionable shades, for example, in the red area are not available.

In spite of enjoy this variety of modern hair dyeing methods the plant colors based on natural dyes, such as Henna, again a growing popularity. This is among other things due to the fact that many consumers the need is growing, a hair dyeing product to use that also meets the requirements of health, ecology and sustainability is enough. However, these have Colorants often have poor pick-up behavior, unconvincing fastness properties and a low Gray cover on.

It became part of the work underlying this application now surprisingly found that hair color-changing Natural dyestuffs based on at least one special Polysaccharide and an optionally hydrogenated vegetable oil are sufficiently stable and to satisfactory colorations lead by multiple application, d. H. by color composition, can also be intense. The colorants allow dyeing with simultaneous care the fibers, which are characterized by an increased gloss, a pleasant Smoothness (surface smoothing) and strengthening can make the fibers noticeable.

• – mindestens einen Naturfarbstoff,

The Color-changing agents contain the essential to the invention Components according to the invention preferably in one suitable aqueous, alcoholic or aqueous-alcoholic Carrier. For the purpose of hair coloring are such Carriers such as creams, emulsions, gels or else surfactant-containing foaming solutions, such as Shampoos, foam aerosols or other preparations intended for the application on the hair are suitable.

For the purposes of the present invention, aqueous-alcoholic solutions are to be understood as meaning aqueous solutions containing from 3 to 70% by weight of a C ₁ -C ₄ -alcohol, in particular ethanol or isopropanol. The compositions of the invention may additionally contain other organic solvents, such as glycerol, methoxybutanol, benzyl alcohol, ethyl diglycol or 1,2-propylene glycol. Preference is given to all water-soluble organic solvents.

According to the invention, a carrier has proved to be advantageous, the water, a C ₁ -C ₄ alcohol, especially ethanol, and glycerol. In the context of this embodiment, it has proven to be advantageous if these three components are contained in a weight ratio that come to 1 part of glycerol 1 to 3 parts of C ₁ -C ₄ -alcohol and 3 to 15 parts of water. Particularly preferred is a weight ratio of 1 part of glycerol to 1.5 to 2.5 parts of C ₁ -C ₄ -alcohol to 8 to 11 parts of water.

Farther was found in the framework of the work carried out that the effects of the invention further increased can be when the inventive Agents contain at least one fatty alcohol.

However, the fatty alcohols are derived from preferably natural fatty acids, which can usually be based on recovery from the esters of fatty acids by reduction. Also usable according to the invention are those fatty alcohol cuts which are produced by reducing naturally occurring triglycerides such as beef tallow, palm oil, peanut oil, rapeseed oil, cottonseed oil, soybean oil, sunflower oil and linseed oil or fatty acid esters formed from their transesterification products with corresponding alcohols, and thus represent a mixture of different fatty alcohols. Such substances are, for example, under the names Stenol ^® , z. B. Stenol ^® 1618 or Lanette ^®, z. B. Lanette ^® O or Lorol ^®, z. B.

Of course, wool wax alcohols, as are commercially available, for example under the names of Corona ^®, White Swan ^®, Coronet ^® or Fluilan ^® can be used according to the invention.

Completely according to the invention particularly preferred fatty alcohols are products containing such Fatty alcohol cut, as found by reduction of naturally occurring Triglycerides is formed. Further preferred according to the invention Fatty alcohols are cetyl alcohol, stearyl alcohol, lauryl alcohol and Octyldodecanol. Lauryl alcohol is an invention particularly preferred unbranched fatty alcohol.

Completely according to the invention particularly preferred is a mixture of at least one straight-chain fatty alcohol, in particular cetyl alcohol, stearyl alcohol and / or lauryl alcohol, and a branched fatty alcohol, especially octyldodecanol.

invention Agents containing xanthan and / or algin in combination with any contain hydrogenated vegetable oil and lauryl alcohol, are particularly preferred. Compositions according to the invention, the xanthan and / or algin in combination with an optionally hydrogenated vegetable oil and octyldodecanol, are particularly preferred. Compositions according to the invention, the xanthan and / or algin in combination with an optionally hydrogenated vegetable oil as well as lauryl alcohol and octyldodecanol are particularly preferred.

in the Frame of another embodiment of the present invention Invention, it has to be advantageous for further increasing the effects of the invention have been found when the inventive Means further contain at least one nonionic surfactant.

On The field of color-changing agents is becoming frequent nonionic surfactants used, the polyethylene glycol and / or Have polypropylene glycol units. Although this principle be included in the inventive compositions can, it has proved extremely beneficial in relation to the objects of the invention proven when the color-changing agents are free of compounds be formulated, the polyethylene glycol or polypropylene glycol units exhibit.

Under The term "free from" is used in this context a content of less than 2% by weight, preferably less than 0.5% by weight, in particular less than 0.05% by weight.
