Description

COMPOSITION FOR CONDITIONING KERATAIN FIBERS

TECHNIAL FIELD

The present invention relates to a composition for conditioning keratin fibres, in particular human keratin fibres such as the hair. The present invention also relates to a cosmetic process for conditioning keratin fibres.

BACKGROUND ART

The hair is generally damaged and weakened by the action of external atmospheric agents such as light, weather, and/or the action of mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent and /or straightening.

There are many products available for altering the natural color of hair. The process of altering the color of hair can involve either depositing an artificial color onto the hair, which provides a different shade or color to the hair, or lifting the color of the hair, for example, from a dark brown shade to a medium brown or a light brown shade. Hair color can be changed using permanent, semi-permanent, or temporary hair-coloring products.

Many consumers desire a permanent color change and therefore use products containing permanent dyes. Conventional permanent hair coloring products are dye compositions comprising oxidation dye precursors, which are also known as primary intermediates or couplers. These oxidation dye precursors are colorless or weakly colored compounds which, when combined with oxidizing products, give rise to colored complexes by a process of oxidative condensation. The oxidizing products conventionally use peroxides such as hydrogen peroxide as oxidizing agents. Such permanent hair color products also contain ammonia or other alkalizing agents such as monoethanolamine (MEA) which causes the hair shaft to swell, thus allowing the small oxidative dye molecules to penetrate the cuticle and cortex before the oxidation condensation process is completed. The resulting larger-sized colored complexes from the oxidative reaction are then trapped inside the hair fiber, thereby permanently altering the color of the hair. Newly, permanently colored hair usually has a vibrant, shiny, and rich appearance.

However, in just a few short weeks, or in some cases even less, the color begins to fade due to washing or exposure to environmental conditions. For instance, gorgeous rich brown colors become muddy and dull, beautiful shades of blonde turn brassy, and vibrant reds do not look so vibrant anymore, resulting in golden, orange or brownish tonalities not desirable to the consumer, especially in fragile areas, and more particularly at the ends leading to split ends.

Efforts have been made to formulate composition for conditioning the hair, wherein the composition comprises dyes for providing color retouch effect.

However, hair care compositions containing dyes have a problem in that they tend to become unstable due to light and/or elevated temperature.

There is therefore a need to develop compositions which can provide a color retouch effect and are stable under light and/or elevated temperature for an expected period of time.

SUMMARY OF THE INVENTION

An object of the present invention is thus to develop a composition which can provide a color retouch effect on keratin fibres, in particular human keratin fibres such as the hair, and are stable under light and/or elevated temperature for an expected period of time.

Thus, according to a first aspect, the present invention provides a composition for conditioning keratin fibres, comprising:

a) at least one lipophilic dye;

b) at least one lipophilic UV filter;

c) at least one lipophilic phenolic antioxidant; and

d) at least one oil.

According to a second aspect, the present invention provides a cosmetic process for conditioning keratin fibers comprising applying the composition as described above to the keratin fibers.

The inventors have found that with the combination of a) at least one lipophilic dye, b) at least one lipophilic UV filter, and c) at least one lipophilic antioxidant, the composition can provide a color retouch effect on keratin fibres and is stable under light and/or elevated temperature of 50 ℃ for at least 24 hours.

Other characteristics and advantages of the invention will emerge more clearly on reading the description and the examples that follow.

According to a preferred embodiment, the lipophilic dye is selected from DC Red 17, DC Red 21, DC Red 27, DC Green 6, DC Yellow 11, DC Violet 2, DC Orange 5, Sudan Red, Sudan brown, quinoline yellow, annatto, curcumin, carotenes, xanthophylls, lipophilic green dyes and a mixture thereof.

Among the carotenes, mention can be made to, in particular, α-carotene, β-carotene, lycopene.

Among the carotenes, β-carotene will be used more particularly (CI 40800, CI 75130, Food Orange 5 or Natural Yellow 26) . The β-carotene molecule is a chain consisting of 8 isoprenic units with alternating single and double bonds, and has the following formula:

β-carotene is found in some fruits and vegetables: pepper, carrot, spinach, lettuce, tomato, sweet potato, broccoli, cantaloupe, squash, apricot. β-carotene can be obtained either by extraction, by synthesis or by biotechnological means. Natural β-carotene comes mainly from red palm oil and alfalfa and also from carrot oil.

According to a particularly preferred form, β-carotene will be used in the form of a dispersion in an oil such as a 30%dispersion of β-carotene in sunflower oil, such as the product sold under the trade name 409185 CAROTENE-DISPERSION NATURAL 30%L-OS E-160A manufactured by LCW -Sensient Cosmetic Technologies or the 30%dispersion in corn oil, such as the product sold under the trade name 30%Beta Carotene FS (Fluid Suspension) by the company DSM Nutritional Products, Inc.

Among the xanthophylls, mention can be made to, in particular:

astaxanthin

Among the xanthophylls, there will be used more particularly the astaxanthin of formula:

Astaxanthin is usually extracted from the alga Haematococcus pluvialis. It belongs to the family of terpenes, and is part of the phytochemicals. It is present in crustaceans (crabs, shrimps, lobster, crayfish, lobsters) , salmon, sea bream and in the feathers of some birds. It can be considered as the ultimate term of a series of hydroxylations and oxidations from β-carotene.

According to a particularly preferred form, the astaxanthin will be used in the form of a dispersion in an oil such as a 5% dispersion of astaxanthin from Euphausia Superba in a caprylic/capric triglyceride mixture such as the product sold under the name Commercial ASTAX-S by the company ITANO REFRIGERATED FOOD, or a dispersion of 4.5-7% asthaxanthin in a caprylic/capric triglyceride mixture extracted from seaweed HAEMATOCOCCUS PLUVIALIS as the product sold under the trade name ASTA TROL-X by FUJI COLOR, or the product sold under the trade name BIOASTIN 5% OLEORESIN by the company CYANOTECH.

It is also possible to mention asthaxanthin dispersions in a caprylic/capric triglyceride mixture extracted from HAEMATOCOCCUS PLUVIALIS algae, such as AM Asta-SOD commercial products from Athena Co LTD; the Astaxanthin-5C and Astaxanthin-PC1 commercial products by Oryza Oil & Fat Chemical Co.

By "green dye" is meant any organic cosmetic or dermatological dye capable of absorbing light radiation of wavelength between 400 and 500 nm and those of wavelength between 600 and 700 nm.

Among the lipophilic green dyes that may be used according to the invention, mention may be made of quinizarin (Ceres Green BB, D&C Green No. 6, CI 61565, 1, 4-Di-p-toluidoanthraquinone, Green No. 202, Quinizarin Green SS) of formula:

Among the lipophilic green dyes, chlorophylls may also be mentioned more preferably. Chlorophylls consist of four ring-shaped pyrrole rings as a complex of a divalent cation and a long-chain alcohol such as phytol. There are several forms of chlorophyll differentiable according to their chemical structure. Chlorophyll exists in all plants, chlorophyll b is found in higher plants and green algae. Two other variants exist in brown algae and some cyanobacteria, respectively chlorophylls c and d. The divalent cation (s) present in chlorophylls are generally selected from alkali metals such as sodium or potassium, alkaline earth metals such as calcium, magnesium and transition metals such as copper and iron or mixtures thereof.

It is preferable to use a chlorophyll in the form of a copper complex and more particularly in the form of a dispersion in an oil such as sunflower oil or grape seed oil, such as the commercial products CHLOROPHYLLE LIPOSOLUBLE W 7208, 503509 COPPER CHLOROPHYLL 15%L -OS and CHLOROPHYLLE LIPOSOLUBLE W 7208 sold by LCW -Sensient Cosmetic Technologies.
