7.Description:
(en)This application claims benefit of U.S. Provisional Application No. 61/150,450, filed Feb. 6, 2009. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 0807306, filed Dec. 19, 2008.


The present application is related to a composition for the oxidation dyeing of keratin fibers.
It is known practice to dye keratin fibers, such as human hair, with dye compositions containing oxidation dyes, such as oxidation dye precursors and coloring modifiers.
Oxidation dye precursors, generally known as oxidation bases, are initially colorless or weakly colored compounds, which, in combination with oxidizing products, can give rise, via an oxidative condensation process, to colored and coloring compounds. They may be, in general, compounds such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic bases.
It is also known that it is possible to vary the shades obtained with these oxidation bases by combining them with couplers or coloring modifiers, the latter generally being chosen from, for example, meta-diaminobenzenes, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds such as indole compounds.
The variety of the molecules involved as oxidation bases and couplers may make it possible to obtain a rich range of colors.
The “permanent” coloring that may be obtained by virtue of these oxidation dyes, also called oxidation dyeing, should, moreover, meet a certain number of requirements. Thus, it should have no toxicological drawbacks, it should allow shades to be obtained in the desired strength, and it should show good fastness with respect to external attacks such as light, bad weather, washing, permanent-waving, perspiration, and rubbing.
The dyes should also allow white hair to be covered and, finally, should be as nonselective as possible, i.e. they should make it possible to obtain the smallest possible differences in coloring along the length of the same keratin fiber, which is generally differently sensitized (i.e. damaged) between its end and its root.
Attempts have been made, in the hair-dyeing field, to improve the dyeing properties by the use, for example, of adjuvants. However, the choice of these adjuvants may be tricky in so far as they should improve the dyeing properties of the dye compositions without being detrimental to the other properties of these compositions. For example, adjuvants should not be detrimental to the keratin fiber-lightening properties and the coloring application properties.
The present disclosure is related to novel compositions for the oxidation dyeing of keratin fibers which may not have the drawbacks of the prior art. For example, one objective of the present disclosure is to obtain compositions for the oxidation dyeing of keratin fibers, which have improved dyeing properties which may make it possible to achieve the desired lightening and which may be easy to mix and to apply. The term “improved dyeing properties” is intended to mean, for example, an improvement in the level of strength/intensity and/or homogeneity of the dyeing.
This objective may be achieved by virtue of the present disclosure, which relates to a composition for the oxidation dyeing of keratin fibers, for example, human keratin fibers such as the hair, the composition intended to be mixed at the time of use with an oxidizing agent, comprising:
A) at least one oxidation base chosen from para-aminophenols and the addition salts thereof with an acid; B) at least one additional dye precursor different from the at least one oxidation base defined in A); and C) dipropylene glycol; wherein: the at least one oxidation base is present in an amount of greater than or equal to 1.5% by weight, relative to the total weight of the composition; and the dipropylene glycol is present in an amount of greater than or equal to 3.5% by weight, relative to the total weight of the composition.

The composition according to the present disclosure may be produced without difficulty. It may not exhibit untimely crystallization of the dyes, for example, of the para-aminophenols.
The composition in accordance with the present disclosure may exhibit, after mixing with an oxidizing agent, improved dyeing properties. For example, the composition of the disclosure, which may be applied without difficulty to the keratin fibers, may result in colorings which exhibit good strength and/or intensity and/or good homogeneity of the color along the fiber between the end and the root of the hairs (also referred to as coloring selectivity) and/or good chromaticity.
Finally, the colorings obtained may be fast and may withstand the various external attacks that keratin fibers may be subjected to.
The present disclosure is also related to a process for dyeing keratin fibers using the composition disclosed herein.

For each of Examples 1 and 2, compositions 1, 2, and 3 were mixed at the time of use in the following proportions: 10 g of composition 1 with 4 g of composition 2 and 16 g of composition 3. The resultant mixture was applied to locks of natural grey hair containing 90% of white hairs, in a bath ratio of 10 g of mixture per 1 g of hair. After a leave-on time of 30 minutes, the hair was rinsed, washed with a standard shampoo, and dried.
The hair coloring was evaluated visually. The results obtained are provided in the following table:

Example 3
Compositions 2 and 3 of Example 2 were mixed weight for weight, and the resultant mixture was applied to natural or permanent-waved grey hair containing 90% white hairs, in a bath ratio of 10 g of mixture per 1 g of hair.
After a leave-on time of 30 minutes, the hair was rinsed, washed with a standard shampoo, and dried. A relatively nonselective coloring was obtained.
