Definitions
- the present disclosure relates to a novel family of N-alkylheteroaryl secondary para-phenylenediamines, to their preparation, and to their use in the oxidation dyeing of the hair.
- oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation.
- couplers or coloration modifiers the latter being chosen, for example, from meta-diaminobenzenes, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds such as indole compounds.
- the “permanent” coloration obtained by means of these oxidation dyes typically may have at least one of the following properties: no toxicological drawbacks, allows shades of the desired intensity to be obtained, and shows good resistance to external agents such as light, bad weather, washing, permanent waving, perspiration and rubbing.
- Other properties that may be possessed by such dyes include: allowing white hairs to be covered and being as unselective as possible, i.e., allowing the smallest possible differences in coloration to be produced over the entire length of the same keratin fiber, which may be differently sensitized (i.e. damaged) between its end and its root.
- the present disclosure is directed to a novel family of N-alkylheteroaryl secondary para-phenylenediamines, which in one embodiment are capable of giving strong, aesthetic and sparingly selective colorations in varied shades, which may show good resistance to the various attacking factors to which the fibers may be subjected.
- the present disclosure also relates to a process for preparing these secondary para-phenylenediamines and also to their use in the oxidation dyeing of the hair.
- compositions for dyeing keratin fibers for example, human keratin fibers such as the hair, comprising at least one N-alkylheteroaryl secondary para-phenylenediamine.
- composition of the present disclosure makes it possible to obtain a very strong and sparingly selective coloration of keratin fibers, which is fast, for example, with respect to light, while at the same time avoiding the degradation of these fibers.
- these compositions may have a good toxicological profile.
- the present disclosure is directed to a dyeing process using this composition for the dyeing of keratin fibers, for example, human keratin fibers such as the hair and also a kit comprising at least two compartments.
- alkyl means a linear or branched C 1 -C 15 radical, for example, methyl, ethyl, n-propyl, isopropyl, butyl, etc.
- an alkoxy radical is a radical alk-O, the alkyl radical having the definition given above, for example methyloxy or ethyloxy.
- halogen means Cl, Br, I or F.
- novel N-alkylheteroaryl secondary para-phenylenediamines are compounds of formula (I) and the addition salts thereof:
- R is a linear or branched C 2 -C 4 alkylene radical.
- R′ is chosen from pyridine, pyrazole, and thiophene group.
- addition salts of the oxidation bases and couplers that may be used in the context of the disclosure are chosen, for example, from the addition salts with an acid, such as the hydrochlorides, hydrobromides, sulfates, citrates, succinates, tartrates, lactates, tosylates, benzenesulfonates, phosphates, and acetates.
- an acid such as the hydrochlorides, hydrobromides, sulfates, citrates, succinates, tartrates, lactates, tosylates, benzenesulfonates, phosphates, and acetates.

- the second step is a standard reduction step, for example, by performing a hydrogenation reaction via heterogeneous catalysis in the presence of Pd/C, Pd(II)/C or Raney Ni, or alternatively by performing a reduction reaction with a metal, for example with zinc, iron, tin, etc. (Advanced Organic Chemistry, 4 th edition, 1992, J. March, Wiley Interscience; Reduction in Organic Chemistry, M. Hudlicky, 1983, Ellis Honwood series Chemical Science).
- the present disclosure also is directed to the nitro compounds of formula (II) and processes for preparing the secondary para-phenylenediamine compounds of formula (I), wherein the step of reduction of the corresponding nitro compound of formula (II) is performed.
- the present disclosure also relates to the compound of formula (I) and the addition salts thereof for the oxidation dyeing of the hair:

Abstract
The present disclosure is directed to a family of N-alkylheteroaryl secondary para-phenylenediamines, to their preparation, and to a cosmetic composition for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising, in a suitable dyeing medium, at least one N-alkylheteroaryl secondary para-phenylenediamine. Further disclosed herein is a process of dyeing keratin fibers, a ready-to-use composition, and a kit comprising at least two compartments.
Description
- This application claims benefit of U.S. Provisional Application No. 60/568,263, filed May 6, 2004, and French Application No. 0402024 filed on Feb. 27, 2004.
- The present disclosure relates to a novel family of N-alkylheteroaryl secondary para-phenylenediamines, to their preparation, and to their use in the oxidation dyeing of the hair.
- It is known practice to dye keratin fibers, and for example, human hair, with dye compositions comprising oxidation dye precursors, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols, and heterocyclic compounds, which are generally referred to as oxidation bases. These oxidation bases, are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds by a process of oxidative condensation.
- It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or coloration modifiers, the latter being chosen, for example, from meta-diaminobenzenes, meta-aminophenols, meta-diphenols, and certain heterocyclic compounds such as indole compounds.
- The variety of molecules used as oxidation bases and couplers makes it possible to obtain a wide range of colors.
- It is desirable for the “permanent” coloration obtained by means of these oxidation dyes to satisfy a certain number of requirements. For example, such a coloration typically may have at least one of the following properties: no toxicological drawbacks, allows shades of the desired intensity to be obtained, and shows good resistance to external agents such as light, bad weather, washing, permanent waving, perspiration and rubbing.
- Other properties that may be possessed by such dyes include: allowing white hairs to be covered and being as unselective as possible, i.e., allowing the smallest possible differences in coloration to be produced over the entire length of the same keratin fiber, which may be differently sensitized (i.e. damaged) between its end and its root.
- The present disclosure is directed to a novel family of N-alkylheteroaryl secondary para-phenylenediamines, which in one embodiment are capable of giving strong, aesthetic and sparingly selective colorations in varied shades, which may show good resistance to the various attacking factors to which the fibers may be subjected. The present disclosure also relates to a process for preparing these secondary para-phenylenediamines and also to their use in the oxidation dyeing of the hair.
- An aspect of the disclosure is novel compositions for dyeing keratin fibers, for example, human keratin fibers such as the hair, comprising at least one N-alkylheteroaryl secondary para-phenylenediamine.
- The composition of the present disclosure makes it possible to obtain a very strong and sparingly selective coloration of keratin fibers, which is fast, for example, with respect to light, while at the same time avoiding the degradation of these fibers. In addition, these compositions may have a good toxicological profile.
- In one embodiment, the present disclosure is directed to a dyeing process using this composition for the dyeing of keratin fibers, for example, human keratin fibers such as the hair and also a kit comprising at least two compartments.
- Other characteristics, aspects, subjects and advantages of the present disclosure will emerge even more clearly on reading the description and the examples that follow.
- In the context of the present disclosure, the term “alkyl” means a linear or branched C1-C15 radical, for example, methyl, ethyl, n-propyl, isopropyl, butyl, etc. In addition, an alkoxy radical is a radical alk-O, the alkyl radical having the definition given above, for example methyloxy or ethyloxy. As used herein, the term “halogen” means Cl, Br, I or F.
