Patent Application

The present invention relates to a cosmetic composition for treating keratin fibres, in particular human keratin fibres such as the hair, comprising at least propane-1,3-diol in a content as defined hereinafter, at least one alkanolamine in a content as defined hereinafter, at least one fatty substance other than fatty acids, and at least one oxidation dye.
The present invention also relates to a process for dyeing keratin fibres, such as the hair, in which the composition as described previously, and comprising at least one oxidation dye is applied to said fibres.
The present invention also relates to the use of the composition according to the invention for dyeing keratin fibres such as the hair.
In the processes for dyeing keratin fibres, it is known practice to dye keratin fibres via various techniques using direct dyes for non-permanent dyeing, or oxidation dye precursors for permanent dyeing.
Non-permanent dyeing or direct dyeing consists in dyeing keratin fibres with dye compositions containing direct dyes. These dyes are coloured and colouring molecules that have affinity for keratin fibres. They are applied to the keratin fibres for a time necessary to obtain the desired colouring, and are then rinsed out.
Some of these dyes may be used under lightening conditions, which enables the production of colourings that are visible on dark hair.
It is also known practice to dye keratin fibres permanently via oxidation dyeing. This dyeing technique consists in applying to the keratin fibres a composition containing dye precursors such as oxidation bases and couplers. Under the action of an oxidizing agent, these precursors form one or more coloured species in the hair.
Existing dyeing processes generally use cosmetic compositions comprising a certain number of ingredients for which the regulatory conditions are increasingly strict. It is thus necessary to develop compositions comprising alternative ingredients.
Consumers are notably in search of dyeing that are more environmentally friendly, notably based on ingredients of natural origin, and which have good working qualities, are easy to use and give good dyeing properties.
Furthermore, the “natural” dyeing compositions currently available on the market do not make it possible to obtain colourings that are sufficiently persistent in the face of external agents such as light, perspiration, washing, or else rubbing.
Moreover, such compositions are not entirely satisfactory either in terms of the cosmetic properties of the hair.
The performance of the colourings obtained with such compositions is also lower compared to the performance obtained with conventional dye compositions, notably in terms of colour build-up, power and chromaticity.
Thus, there is a real need for a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, which is more environmentally friendly and which does not have the abovementioned drawbacks, i.e. which is capable of resulting in a good performance, notably in terms of colour build-up, power and chromaticity while at the same time having low selectivity and good persistence and which is capable of giving good dyeing performance, and/or good lightening performance, even after a period of storage, while at the same time having good working qualities.
One subject of the present invention is therefore a composition comprising:
The composition according to the invention makes it possible to achieve the above objectives, notably in terms of colour build-up, dyeing power, chromaticity, selectivity, persistence and also of good working qualities.
The composition according to the invention also makes it possible to result in a good cosmetic quality, notably in terms of sheen, a more natural feel, and comfort, while preserving the integrity of the fibre.
Furthermore, the composition according to the invention exhibits good stability, notably upon storage. The composition notably comprises oxidation dyes and/or other compounds in the form of salts.
The composition according to the invention furthermore has a smaller change in its appearance, notably less browning, during the use thereof.
Moreover, the composition according to the invention has good working qualities, notably a creamy texture allowing quick and easy mixing with an oxidizing composition, where appropriate, and easy and uniform spreading over the entire head of hair. The composition according to the invention has good stability over time, notably little or no change in its viscosity during storage.
The present invention also relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which a composition is applied to said fibres, comprising:
The present invention also relates to the use of the composition according to the invention for dyeing keratin fibres, in particular human keratin fibres such as the hair.

At the moment of use, each of the compositions A1, A2 and B1 is mixed with one and a half times of composition C1.
Each of the mixtures is then applied to a lock of moderately sensitized hair (alkaline solubility AS20), in a proportion of 5 g of mixture per gram of hair.
After a leave-on time of 30 minutes on a plate thermostatically regulated at 27° C., the hair is rinsed, washed with a standard shampoo and dried.
The colouring of the hair is evaluated in the L*a*b* system, using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10°, specular component included) in the CIELab system.
In this system, L* represents the lightness. The lower the value of L*, the darker and more powerful the colouring obtained. The chromaticity is measured by the values a* and b*, a* representing the red/green axis and b* the yellow/blue axis.
The chromaticity is given by the following formula:
The higher the value for C*, the better the chromaticity of the colour obtained.
The results are given in the table below:
The compositions according to the invention, A1 and A2, respectively comprising 3% and 5% by weight of propane-1,3-diol, lead to a better chromaticity compared to the comparative composition B1 not comprising any propane-1,3-diol.
