COMPOSITION FOR OXIDATION DYEING OF THE KERATIN FIBER CONTAINING p-AMINOPHENOL, DIPROPYLENE GLYCOL AND ADDITIONAL DYE PRECURSOR

The subject of this application is a composition for oxidative dyeing of keratin fibers.

It is known to dye keratin fibers, especially human hair, with dye compositions containing oxidative dyes, especially oxidative dye precursors and toning agents.

Oxidation dye precursors, commonly known as oxidative bases, are initially colorless or lightly colored compounds that combine with oxidative products during the oxidative condensation process to give colored and colored compounds. Can be done. These are generally compounds such as o- or p-phenylenediamine, o- or p-aminophenols and heterocyclic bases.

It is also known that it is possible to change the color tone obtained by these oxidizing bases by combining the oxidizing bases with a coupler or a toning agent, and the latter are generally m-diaminobenzene, m-aminophenol, m. -Selected from several heterocyclic compounds such as diphenols and indole compounds.

The various molecules involved as oxidative bases and couplers make it possible to obtain a wide range of colors.

The "permanent" coloring (also called oxidative dyeing) obtained by these oxidative dyes should meet some additional requirements. Therefore, this coloring should not have toxicological drawbacks and should allow the color tones to be obtained at the desired intensity and against external attacks such as light, bad weather, cleaning, perms, sweating and rubbing. It should show good robustness.

This dye should also be able to hide gray hair and should ultimately be as non-selective as possible, i.e., usually differently increased sensitivity between its tip and its roots ( That is, it should be possible to obtain the least possible color difference along the same keratin fiber (damaged).

In the field of hair dyeing, many attempts have been made to improve dyeing properties, for example by means of auxiliaries. However, the selection of these auxiliaries is difficult because the dyeing properties of the dye composition should be improved without harming the other properties of these compositions. In particular, these auxiliaries should not impair the lightening and coloring applied properties of keratin fibers.
