Description

The present invention relates to compositions for conditioning keratin fibers, particularly human keratin fibers such as hair. The present invention also relates to cosmetic methods for conditioning keratin fibers.

Hair is affected by the action of atmospheric agents such as light, climate and/or mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, permanent waving and/or straightening. It is common to be damaged and embrittled by

Many products are available that change the natural color of hair. Methods for changing the color of hair include depositing an artificial color on the hair (which results in a different hue or color to the hair), or changing the color of the hair, for example , to lift from a dark brown shade to a medium brown or light brown shade. Hair color can be changed using permanent hair color, semi-permanent hair color, or hair manicure products.

Many consumers desire a permanent color change and therefore use products containing permanent dyes. Conventional permanent hair color products are dye compositions containing oxidation dye precursors, also known as initial intermediates or couplers. These oxidation dye precursors are colorless or slightly colored compounds which, when combined with oxidation products, produce colored complexes through a process of oxidative condensation. Oxidation products typically use a peroxide such as hydrogen peroxide as the oxidizing agent. Such permanent hair color products also contain alkaline agents, such as ammonia or monoethanolamine (MEA), which swell the hair shaft, allowing small molecules of the oxidative dye to reach the cuticle and It can penetrate the cortex. The larger colored complexes resulting from the oxidation reaction are then trapped inside the hair fibres, thereby permanently changing the shade of the hair. Freshly colored hair usually has a persistent, bright, intense, lustrous, dark appearance.

However, in as little as a few weeks, or in some cases even shorter, the color will begin to fade with washing or exposure to environmental conditions. For example, bright dark brown colors become muddy dull, beautiful blonde hues become gaudy, bright intense reds appear less bright and intense, and as a result gold, orange or brown tones are particularly vulnerable. More specifically, the ends leading to the split ends of the split ends are less desirable to the consumer.

Attempts have been made to formulate compositions for conditioning hair that contain dyes to provide color modifying benefits.

However, hair care compositions containing dyes have the problem that they tend to become unstable with light and/or elevated temperatures.

Therefore, there is a need to develop compositions that can provide color-modifying benefits and that are stable under light and/or elevated temperature over time.

Among the carotenes, α-carotene, β-carotene and lycopene can be mentioned in particular.

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

β-Carotene is found in some fruits and vegetables: peppers, carrots, spinach, lettuce, tomatoes, sweet potatoes, broccoli, cantaloupe, pumpkin, apricots. β-carotene can be obtained either by extraction, synthetic or biotechnological methods. Natural beta-carotene is mainly derived from red palm oil and alfalfa, and also from carrot oil.

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

Astaxanthin is commonly extracted from the algae Haematococcus pluvialis. It belongs to the family of terpenes and is part of the phytochemicals. It is present in crustacean animals (crab, shrimp, lobster, crayfish, lobster), salmon, sea bream, and in the feathers of some birds. This can be thought of as the final step in a series of hydroxylations and oxidations from β-carotene.

According to a particularly preferred form, the astaxanthin is in the form of a dispersion in oil, e.g. a 5% dispersion of Euphausia Superba astaxanthin in a caprylic/capric triglyceride mixture, e.g. or in caprylic/capric triglyceride mixtures extracted from the seaweed Haematococcus pluvialis, such as products sold under the trade name ASTA TROL-X by FUJI COLOR or products sold under the trade name OLEORESIN by CYANOTECH.

Two other variants, chlorophyll c and d, are present in brown algae and some cyanobacteria, respectively. Divalent cations present in chlorophyll 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.

Chlorophyll in the form of copper complexes, more particularly in the form of dispersions in oils such as sunflower oil or grapeseed oil, such as the products CHLOROPHYLLE LIPOSOLUBLE W 7208, 503509 COPPER CHLOROPHYLL sold by LCW - Sensient Cosmetic Technologies.
