Description

Technical Field

[0001] The present invention relates to a composition for dyeing keratin fibers, in particular human keratin fibers, such as the hair.

[0002] background

[0003] Many people have long tried to change the color of their hair, especially to dye it, for example to cover their gray hair.

[0004] In order to dye human keratin fibers in a permanent manner, "permanent" dyeing processes, also called oxidation dyeing, have been developed using colorant compositions containing oxidation dye precursors, which are generally called oxidation bases, such as o- or p-phenylenediamine, o- or p-aminophenol and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds, which, when combined with oxidizing products, can produce colored compounds via an oxidative condensation process.

[0005] The dyeing product may comprise at least one oxidation dye and at least one oxidizing agent. For better use, the oxidation dye and the oxidizing agent may be placed in a multi-compartment package respectively and mixed together just before use.

[0006] Consumers want to use dyes to color only the target areas. However, in many cases, such as when dyeing hair, some other areas may be accidentally stained (stained), such as hands, face, ears, etc. Consumers have to pay more attention to avoid undesired areas and are always looking for products to help them remedy undesired coloring. SUMMARY OF THE INVENTION

[0008] The inventors have now discovered that the use of specific retarders together with oxidation dyes makes it possible to obtain compositions for oxidative dyeing of keratin fibres which overcome the above-mentioned disadvantages and in particular reduce or even substantially avoid staining of non-target sites by dyes.

[0009] A subject of the present invention is therefore a dye package for the oxidative dyeing of keratin fibers, comprising:

[0010] (A) a dyeing composition (A); and

[0011] (B) AMPS composition (B) comprising an AMPS polymer.

[0012] Preferably, the AMPS composition (B) is placed in a separate chamber from the dyeing composition (A).

[0013] According to one embodiment of the present invention, the dyeing composition (A) may comprise, in order:

[0014] (I) A colorant composition (I) comprising:

[0015] i) at least one oxidation dye; and

[0016] (II) A developer composition (II), comprising:

[0017] ii) at least one color developing agent.

[0018] The present invention therefore provides the use of AMPS polymers as retardants for slowing down the reaction of dyes or their intermediates.

[0019] The present invention also provides the use of AMPS polymers for reducing dye staining.

[0020] The invention also relates to a process for dyeing keratin fibers, in particular human keratin fibers, such as the hair, using the dye composition (A) according to the invention.

[0021] The present invention also relates to a method for slowing down the reaction of a dye or an intermediate thereof, characterized in that an AMPS polymer is mixed with the dye. Preferably, the AMPS polymer is mixed with the dye before the dye is applied, or the AMPS polymer is applied to a location where the dye has been applied for less than 10 minutes, less than 5 minutes or less than 3 minutes.

[0078] Other antioxidants

[0079] In addition to the reducing agents described above, one or more further antioxidants may also be used in the colorant composition (I) according to the invention.

[0080] Antioxidants used may include natural exogenous phytochemical antioxidants such as phenols and carotenoids.

[0081] Antioxidants may include flavonoids. Flavonoids constitute a large class of more than 5000 polyphenolic phytochemicals with antioxidant properties that act by direct free radical scavenging. Flavonoids have anti-inflammatory, antibacterial, antiviral, antiallergic, antimutagenic, antithrombotic, antitumor and vasodilatory effects, and these methods of action can also be used to prevent, reduce or eliminate oxidative damage from dental instruments. Flavonoids also exhibit chelating properties with metal ions and can reduce oxidative damage from metal ions by chelating ions. The formation and stability of flavonoid-metal chelates depends on the functionality of the structure. Flavonoids with a catechol moiety and a hydrogen bond between the hydroxyl groups at the 5- and 3-positions have chelating properties.

[0082] Vitamin C and derivatives can be used, including ascorbic acid, erythorbic acid or its derivatives, such as sodium ascorbate / erythorbic acid and fat-soluble esters tetrahexyldecyl ascorbate / erythorbic acid and ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl glucoside, glucosamine ascorbate, ascorbyl acetate, etc. In addition, plants containing large amounts of vitamin C, such as extracts of Camu (Myrciaria dubia), Acerola, Emblica officinalis, and bioflavonoids from rose hips and citrus, including water-soluble bioflavonoids such as hesperidin methyl chalcone, can also be used.

[0083] Sesame seeds (Sesamum indicum) or lignans may also be added. Sesame seeds and their lignans (fibrous compounds associated with sesame seeds) act as antioxidants. Sesame seed lignans significantly enhance vitamin E activity.

[0084] Other antioxidants that can be incorporated into the compositions of the present invention include tocopherols (e.g., d-α-tocopherol, d-β-tocopherol, d-γ-tocopherol, d-δ-tocopherol), tocotrienol phenols (e.g., d-α-tocotrienol, d-β-tocotrienol, d-γ-tocotrienol, d-δ-tocotrienol) and vitamin E (α-tocopherol acetate). These compounds can be isolated from natural sources, prepared by synthetic means, or mixed. A tocotrienol-rich vitamin E preparation can be obtained by fractionating the vitamin E preparation to remove a portion of the biophenols and recovering a more concentrated tocotrienol product. Available tocotrienols are natural products that are separated from wheat germ oil, grains or palm oil using high performance liquid chromatography or separated from barley, vinasse or oats by alcohol extraction and / or molecular distillation. The term "tocotrienols" as used herein includes tocotrienol-rich fractions obtained from these natural products as well as pure compounds. Increased glutathione peroxidase activity protects the skin from oxidative damage.

[0085] In addition, carotenoids, especially xanthophyll types, are also useful antioxidants that can be used. Xanthophyll type carotenoids include molecules such as lutein, canthaxanthin, cryptoxanthin, zeaxanthin, and astaxanthin.

[0290] Addition form of AMPS polymer

[0291] As mentioned above, the present inventors have surprisingly found that AMPS polymers can be used as retarders to slow down the reaction of dyes or their intermediates, such as oxidation dyes i) useful in composition (I).

[0292] That is, the AMPS polymer mainly acts on the reaction of the dye. Accordingly, for the dye set, the AMPS polymer can be added directly to the dyeing composition (A), for example as a mixture with the colorant composition (I) and / or with the colorant composition (II); or can be added to a separate chamber from the dyeing composition (A), for example in the form of an AMPS composition (B).

[0293] In order to be used as an AMPS composition (B) independently of the dyeing composition (A), composition (B) may comprise any component known in the cosmetic art that is beneficial to the stability of the AMPS polymer.

[0294] Accordingly, the present invention may advantageously provide a dyeing kit comprising:

[0295] a dyeing composition (A) according to the invention placed in chamber 1; and

[0296] The AMPS composition (B) according to the present invention is placed in chamber 2 which is separate from chamber 1.

[0297] use

[0298] The invention also relates to the use of a dye set as described above for dyeing keratin fibers, in particular the hair.

[0299] Another subject of the invention is a method for dyeing human keratin fibers, in particular the hair, using a dye set as described above.

[0300] According to a preferred embodiment, the dyeing process of the invention comprises mixing, just before use, the colorant composition (I) with the composition (II) and applying the mixture obtained as described above to the keratin fibres.

[0301] More particularly, "mixing" or variations thereof is intended to mean the act of placing the colorant composition (I) of the present invention together with the developer composition (II) as described above in a container or in the palm of one's hand, with or without stirring them.

[0302] According to a preferred variant of this preferred embodiment, the colorant composition (I) according to the invention is placed together with the developer composition (II) as described above in a container or in the palm of the hand without stirring them.

[0303] Whatever the method used and whatever the amount of composition used, the above-described composition, optionally premixed, is applied to the wet or dry keratin fibres.

[0304] As described above in the section "Additional Form of AMPS Polymer", the AMPS polymer can be provided in various forms for use with the colorant composition (I) and the developer composition (II) to slow down the reaction of the dye. In particular, for the dye set according to the present invention:

[0305] - If the user does not want to slow down the dyeing, or does not care about staining caused by the dye, chamber 2 can be left unused;

[0306] - If the user wishes to avoid any staining, he / she can mix chamber 2 with 1 before dyeing;

[0307] - if the user wants to determine whether to use chamber 2 based on whether actual staining occurs, he / she can first use only chamber 1, and when the staining composition adheres to the hands or anywhere else, chamber 2 can be applied immediately; and

[0308] - If the user wants to avoid staining and wishes to dye quickly, he / she can pre-apply the chamber 2 to locations where staining is most likely to occur but should be avoided, such as the hands.

[0309] Alternatively, when an AMPS polymer is provided with the colorant composition (I) and / or the developer composition (II), for example added directly to either or both of said compositions, the dyeing process is always slowed compared to the same dyeing process except that no AMPS polymer is present.

[0310] The mixed composition, including the colorant composition (I) and the developer composition (II), and optionally the AMPS composition, is typically left in place on the fiber for a period of time typically from 1 minute to 1 hour, preferably from 5 minutes to 30 minutes.

[0311] The temperature during the process is customarily between 20 and 80° C., preferably between 20 and 60° C. After this treatment, the human keratin fibers are advantageously rinsed with water. They can optionally be further washed with a shampoo, then rinsed with water and then dried or air-dried.

[0312] This process can be repeated several times to obtain the desired coloration.

[0313] The dye kits described above may also be provided with a device for delivering the desired mixture to the hair, such as the device described in patent FR 2 586 913.
