Description

This application claims benefit of U.S. Provisional Application No. 60/856,012, filed Nov. 2, 2006, the contents of which are incorporated herein by reference. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 0654563, filed Oct. 26, 2006, the contents of which are also incorporated herein by reference.
Disclosed herein is a process for wash-protecting the color of keratin fibers, for example, human keratin fibers, such as human hair, comprising applying a composition comprising at least one zinc-based compound chosen from zinc-based mineral compounds and zinc-based non-nitrogenous organic compounds on keratin fibers dyed beforehand by direct dyeing or by oxidation dyeing in the presence of an oxidizing agent.
It is known practice to dye keratin fibers, for example, human keratin fibers such as the hair, with dye compositions comprising oxidation dye precursors, which are generally known as oxidation bases. These oxidation bases are colorless or weakly colored compounds, which, when combined with oxidizing products, give rise to colored compounds via 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 variety of molecules used as oxidation bases and couplers allows a wide range of colors to be obtained.
It is also known practice to dye keratin fibers by direct dyeing. The process conventionally used in direct dyeing comprises applying to the keratin fibers direct dyes, which are colored and coloring molecules that have affinity for the fibers, leaving them to act, and then rinsing the fibers.
The colorations resulting there from can be for instance, chromatic colorations, but are, however, temporary or semi-permanent. It is believed that the nature of the interactions that bind the direct dyes to the keratin fiber and their desorption from the surface and/or core of the fiber are responsible for their semi-permanent dyeing power and weak wash-fastness.
The artificial color of hair provided by a direct or oxidation dyeing treatment gradually attenuates as a result of repeated washing and leads to fading of the coloration of the hair over time. Furthermore, the use of commercial rinse-out and leave-in care products does not sufficiently improve the fastness of the artificial color of hair.
There is thus a need in the art to develop methods for protecting the artificial color from the effect of repeated washing.
Organic mineral zinc salts are generally known in hair dyeing as catalysts for oxidation dyeing with atmospheric oxygen using specific oxidation dye precursors. In European Patent No. 0 335 403, zinc salts are used for the mild oxidation dyeing of hair with tannins, for instance, catechin or tannic acid. In French Patent No. 2 814 943 and European Patent Application Nos. 1 424 060 and 1 210 931, zinc salts are used in a catalytic system also comprising hydrogen carbonates to develop the color of oxidation dye precursors of the ortho-diphenol type. German Patent No. 4 209 897 and French Patent No. 2 722 685 also describe oxidation dyeing processes based on indole or indoline compounds and zinc salts.
Japanese Patent Application No. 2003-095 897 discloses treating compositions for preventing perturbation of the shade of bleached hair caused by light, shampooing at the time of dyeing or the use of peroxide. These compositions contain a hydroxycarboxylic acid, chosen, for example, copper gluconate, zinc gluconate and 2-glucoside gallic acid.
The present inventors have discovered, surprisingly, that the use of at least one-based compound chosen from zinc-based mineral compounds and zinc-based non-nitrogenous organic compounds affords wash-protection of the artificial color of keratin fibers dyed by direct dyeing or by oxidation dyeing in the presence of an oxidizing agent.

Other than in the examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, unless otherwise indicated the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
The examples that follow are intended to illustrate the present disclosure without, however, being limiting in nature.

EXAMPLE

Dyeing Step

At the time of use, a support oxidation dye composition, Majirouge® 6.66, was mixed weight-for-weight with aqueous hydrogen peroxide solution (L'Oréal Professional 20-volumes 6% aqueous hydrogen peroxide solution).
The mixture was then applied to locks of permanent-waved hair comprising 90% white hairs, at a rate of 10 g of dye mixture/g of lock. The leave-on time was 30 minutes on each side of the lock. The locks were then rinsed with water, and then washed with DOP Camomile shampoo and dried.
a) Protective Treatment Step:
An aqueous lotion comprising 1% by weight of AM (active material) of the zinc salts below:


Applied treatment	Lock

Zinc chloride sold under the reference 21127-3 by Sigma Aldrich	A
Zinc sulfate sold under the reference 108881 by Merck	B
Zinc gluconate sold under the trade name Givobio G Zn 2 by	C
Sigma SEPPIC

was then applied to the entire length of a dyed lock, at a rate of 2 grams per gram of hair.

The treated locks were then left to stand under a hood for 10 minutes.
The treated locks were then shampooed with DOP Camomile® shampoo.
Untreated locks (references) were also shampooed accordingly. The locks were then dried under a hood for 10 minutes at 60° C.
b) Steps of Color Fastness after Shampoo Washing:
The treated locks were then compared with untreated dyed locks in a shampoo wash-fastness test.
Accordingly, the locks were shampooed six times successively with DOP Camomile® shampoo, with intermediate drying.

Evaluation of the Colour Protection:

After the wash-fastness test of the treated and untreated locks, the degradation of the color was evaluated relative to dyed locks that had not undergone this test.
The evaluations were accompanied by spectrocolorimetric monitoring. Measurements were taken using a Minolta CM 2022 spectrocolorimeter.
The degradation caused by the wash-fastness test was thus expressed as ΔE
ΔE(after test−before test)=√{square root over ( )}(ΔL ^*2 +Δa ^*2 +Δb ^*2)
The protection was then expressed as a difference in ΔE between the treated and untreated locks (positive difference=gain in color protection, negative difference=loss of protection).

Results:

After exposure to the wash-fastness test, substantial degradation of the color of the untreated dyed locks was observed (loss of ΔE=7.50).
It was observed, surprisingly, that after this same test, the locks that have been treated with the zinc salts of the present disclosure showed significant protection of the color compared with the untreated locks.
These results were confirmed by the colorimetric measurements, which indicated a significant gain in ΔE relative to the untreated dyed locks.
