Abstract

A subject-matter of the invention is a process for dyeing keratinous substances, in particular keratinous fibers, comprising the application, to the said keratinous fibers: of at least one composition A comprising at least one non-ionic alkylpolyglucoside surfactant, at least one metal salt and at least one thickening polymer and of at least one composition B comprising one or more ortho-diphenol derivative(s).

First claim

The invention claimed is:

1. A process for treatment of keratinous substances, comprising:
applying to the keratinous substances a first composition that comprises:
at least one non-ionic alkylpolyglucoside surfactant;
at least one metal salt; and
at least one thickening polymer;

optionally wiping mechanically, drying, or rinsing the keratinous substances; and
applying to the keratinous substances a second composition, wherein the second composition comprises at least one ortho-diphenol derivative.

2. The process of claim 1 , wherein the at least one non-ionic alkylpolyglucoside surfactant is chosen from compounds of the formula below:
R 1 O—(R 2 O) t (G) v

wherein:
R 1 represents a linear or branched alkyl, or alkenyl radical, comprising from 8 to 24 carbon atoms, or an alkylphenyl radical of which a linear or branched alkyl radical comprises from 8 to 24 carbon atoms;
R 2 represents an alkylene radical comprising from 2 to 4 carbon atoms;
G represents a sugar unit comprising from 5 to 6 carbon atoms;
t is a number ranging from 0 to 10; and
v is a number ranging from 1 to 15.

3. The process of claim 2 , wherein:
R 1 represents a saturated or unsaturated, linear or branched alkyl radical comprising from 8 to 18 carbon atoms;
t is a number ranging from 0 to 3;
G represents glucose, fructose or galactose; and
v is a number ranging from 1 to 15.

4. The process of claim 1 , wherein the at least one non-ionic alkylpolyglucoside surfactant is present in the first composition in an amount ranging from about 0.1% to about 30% by weight of active material relative to the total weight of the first composition.

5. The process of claim 1 , wherein the at least one metal salt is chosen from Mn salts or Zn salts.

6. The process of claim 5 , wherein the Mn salts and Zn salts are independently chosen from halides, sulfates, phosphates, nitrates, perchlorates, carboxylic acid salts, or mixtures thereof.

7. The process of claim 1 , wherein the at least one metal salt is present in the first composition in an amount ranging from about 0.001% to about 10% by weight of active material relative to the total weight of the first composition.

8. The process of claim 1 , wherein the at least one thickening polymer is chosen from polymers having at least one sugar unit.

9. The process of claim 1 , wherein the at least one thickening polymer is chosen from tree or shrub exudates, gums resulting from algae, gums resulting from seeds or tubers, microbial gums, or plant extracts.

10. The process of claim 1 , wherein the at least one thickening polymer is chosen from celluloses or their derivatives.

11. The process of claim 1 , wherein the at least one thickening polymer is present in the first composition in an amount ranging from about 0.01% to about 10% by weight of active material relative to the total weight of the first composition.

12. The process of claim 1 , wherein the at least one ortho-diphenol derivative is chosen from natural ortho-diphenol derivatives.

13. The process of claim 12 , wherein the natural ortho-diphenols are chosen from extracts of animals, bacteria, fungi, algae, or plants.

14. The process of claim 1 , wherein the at least one ortho-diphenol derivative comprises an ortho-diphenol having an aromatic ring chosen from benzene, naphthalene, tetrahydronaphthalene, indane, indene, anthracene, phenanthrene, isoindole, indoline, isoindoline, benzofuran, dihydrobenzofuran, chroman, isochroman, chromene, isochromene, quinoline, tetrahydroquinoline, or isoquinoline, wherein the aromatic ring has at least two hydroxyl groups carried by two adjacent contiguous carbon atoms of the aromatic ring.

15. The process of claim 1 , wherein the at least one ortho-diphenol derivative is chosen from compounds of formula (I) below or one of its oligomers, in salified or non-salified form:

wherein:
R 1 to R 4 each independently represent a hydrogen atom, a halogen atom, a hydroxyl radical, a carboxyl radical, an alkyl carboxylate or alkoxycarbonyl radical, an optionally substituted amino radical, an optionally substituted and linear or branched alkyl radical, an optionally substituted and linear or branched alkenyl radical, an optionally substituted cycloalkyl radical, an alkoxy radical, an alkoxyalkyl radical, an alkoxyaryl radical having an optionally substituted aryl group, an aryl radical, a substituted aryl radical, a saturated or unsaturated heterocyclic radical optionally carrying a cationic or anionic charge and optionally substituted or fused with a substituted or unsubstituted aromatic ring, or a radical containing one or more silicon atoms; and
two of the substituents carried by two adjacent carbon atoms R 1 —R 2 , R 2 —R 3 or R 3 —R 4 together form a saturated or unsaturated, aromatic or non-aromatic, and substituted or unsubstituted ring.

16. The process of claim 1 , wherein the at least one ortho-diphenol derivative is chosen from:
flavonols, anthocyanidins, anthocyanins or anthocyans, ortho-hydroxybenzoates, flavones, hydroxystilbenes, 3,4-dihydroxyphenylalanine and its derivatives, 2,3-dihydroxyphenylalanine and its derivatives, 4,5-dihydroxyphenylalanine and its derivatives, dihydroxycinnamates, ortho-polyhydroxycoumarins, ortho-polyhydroxyisocoumarins, ortho-polyhydroxycoumarones, ortho-polyhydroxyisocoumarones, ortho-polyhydroxychalcones, ortho-polyhydroxychromones, polyhydroxyquinones, orthohydroxyxanthones, 1,2-dihydroxybenzene and its derivatives, 1,2,4-trihydroxybenzene and its derivatives, 1,2,3-trihydroxybenzene and its derivatives, 2,4,5-trihydroxytoluene and its derivatives, proanthocyanidins, proanthocyanins, tannic acid, ellagic acid, or mixtures thereof.

17. The process of claim 1 , wherein:
the first composition and/or the second composition further comprises at least one fatty substance in an amount less than about 10% by weight relative to the total weight of the first composition and/or the second composition; and
the first composition and/or the second composition further comprises at least one oil in an amount less than about 10% by weight relative to the total weight of the first composition and/or the second composition.

18. The process of claim 1 , wherein the first composition further comprises at least one anionic surfactant in an amount less than about 1% by weight relative to the total weight of the first composition.

19. The process of claim 1 , wherein the first composition is applied to the keratinous substances prior to application of the second composition to the keratinous substances.

20. The process of claim 1 , wherein the keratinous substances are not rinsed following application of the first composition and the second composition.
