Description

Retardant composition of oxidation Technical field
The present invention relates to a retardant composition of oxidation, in particular for oxidation of oxidative dyes.
Background
Dyes are widely used for various applications and fields, such as printing, paper, fabrics, cosmetics, medical science, paint, and others. In many situations, a rapid dyeing may be desirable. However, in some other situations, a slow dyeing may be desirable. In particular, a slow dyeing may result in a “revocable” effect of dyeing, allowing modifying or canceling certain undesired dyeing.
For example, many people have for a long time sought to modify the colour of their hair, and especially to dye it in order, for example, to mask their grey hair. The dyeing product can comprise both at least one oxidative dye and at least one oxidant. For better use, the oxidative dye and the oxidant may be placed respectively in a multi-compartment package, and are mixed together immediately before use.
Consumers desire using dyes for dyeing only the target area. However, in many cases, e.g., when dyeing hair, some other areas may be undesiredly dyed (stained) , such as hand, face, ear and the like. Consumers have to pay more attention to avoid the undesired areas, and have been seeking for products help them to remedy the undesired dyeing.
Summary of the invention
The inventors have now discovered that the use of a specific retardant composition comprising a pyrazolidine-3, 5-dione compound makes it possible to slow down the oxidation reaction, especially of an oxidative dye, so as to reduce or even substantially avoid undesired stain by dye to a non-target position which is called as a stainless effect. In particular, when the oxidation reaction involves a polyvalent metal cation, especially calcium, strontium, zinc, copper, ferrum, manganese, aluminum, or mixtures thereof, e.g., a dye product for dyeing hair with high percentage of metal ion, like Cu 2+ or Fe 3+ (e.g. Caucasian hair tends to contain higher Cu 2+) , a chelating agent can be particularly useful  in the retard composition, which can boost the stainless effect.
One subject of the present invention is thus a retardant composition of oxidation, comprising components of:
1) a water soluble chelating agent selected from carboxylic acids comprising at least one heteroatom in addition to the carboxylic group;
2) pyrazolidine-3, 5-dione compound of formula (1) :

Antioxidant
The colorant composition I) can optionally comprise an antioxidant.
The antioxidants used may include natural exogenous phytochemical antioxidants such as phenols and carotenoids.
The antioxidant can include flavonoids. Flavonoids constitute a large class of more than 5,000 polyphenolic phytochemicals with antioxidant properties that act by direct free radical scavenging. Flavonoids have anti-inflammatory, antibacterial, antiviral, anti-allergic, anti-mutagenic, anti-thrombotic, anti-tumor and vasodilating effects and these methods of action can also be used to prevent, alleviate or eliminate oxidative damage from dental instruments. Flavonoids also exhibit chelation properties with metal ions and can mitigate oxidative damage from metal ions by chelating ions. The formation and stability of flavonoid-metal chelate is dependent on the function of the structure. Flavonoids having a catechol moiety and having a hydrogen bond between the hydroxyl groups at the 5-position and the 3-position have chelation properties.
Vitamin C and derivatives can be used, including ascorbic acid, erythorbic acid, or derivatives thereof, e.g., sodium ascorbate/erythorbate and the fat-soluble ester tetrahexyl decyl ascorbate/erythorbate and ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl glucoside, glucosamine ascorbate, ascorbyl acetate, and the like. In addition, it is also possible to use plants derived from a large amount of vitamin C, such as extracts of Myrciaria dubia, acerola, emblica officinalis, and bioflavonoids from rose hips and citrus, including Water-soluble bioflavonoids such as hesperidin methyl chalcone.
Sesamum indicum or lignan may also be added. Sesame and its lignans (fibrous compounds associated with sesame) act as antioxidants. Sesame seed lignan significantly enhances vitamin E activity.
Other antioxidants which may be incorporated into the compositions of the present invention include tocopherols (e.g., d-alpha-tocopherol, d-beta-tocopherol, d-gamma-tocopherol, d-delta-tocopherol) , tocotrienol Phenol (eg d-α-tocotrienol, d-β-tocotrienol, d-γ-tocotrienol, d-δ-tocotrienol) and vitamin E (α-tocopheryl acetate) ) . These compounds can be isolated from natural sources, prepared by synthetic means or mixed. The tocotrienol-rich vitamin E preparation can be obtained by fractionating the vitamin E preparation to remove a portion of the biophenol and recovering the higher concentrated tocotrienol product. Useful tocotrienols are natural products isolated, for example, from wheat germ oil, grain or palm oil using high performance liquid  chromatography or from barley, distiller's grains or oats by alcohol extraction and/or molecular distillation. The term "tocotrienol" as used herein includes a tocotrienol-rich fraction obtained from these natural products as well as a pure compound. Increased glutathione peroxidase activity protects the skin from oxidative damage.
In addition, carotenoids, especially lutein types, are also useful antioxidants that can be used. Lutein-type carotenoids include molecules such as lutein, canthaxantin, cryptoxanthin, zeaxanthin and astaxanthin. Lutein compounds protect compounds such as vitamin A, vitamin E and other carotenoids.
The flavonoid may be a flavanone (a derivative of 2, 3-dihydro-2-phenylbenzopyran-4-one) . Flavanones include: scutellarin, eriodictin, hesperetin, hesperidin, sylvestre, isosakuranetin, naringenin, naringin, pinocin, tangrin (poncirin) ) , sakuranetin, sakura glycosides and 7-O-methyl ergophenol (Sterubin) .

Another subject of the invention is a process for reducing the stain of a dye composition, using the dye kit as described above.
Another subject of the invention is a process for slowing down reactions of dye or intermediates, using the dye kit as described above.
The invention also relates to the use of the dye kit as described above for dyeing keratin fibers, in particular the hair.
The invention also relates to the use of the dye kit as described above for reducing the stain of the dye kit.
The invention also relates to the use of a dye kit as described above for slowing down reactions of dye or intermediates, using the dye kit as described above.
In particular, the invention relates to a process of slowing down reactions of dye or intermediates thereof, characterized in mixing the retardant composition A) comprising a pyrazolidine-3, 5-dione compound of formula (1) and the chelating agent 2) with the dye.
Preferably, the retardant composition A) is mixed with the dye before application of the dye, or the retardant composition A) is applied to the position to which the dye has been applied for less than 10 minutes, less than 5 minutes, or less than 3 minutes.
The present invention also relates to the use of the retardant composition A) for reducing stain of a dye.
In another aspect, the present invention relates to the use of a retardant composition A) for dyeing keratin fibers, while reducing the stain in areas other than the keratin fibers, wherein the retardant composition A) comprises a pyrazolidine-3, 5-dione compound of formula (1) and a water soluble chelating agent selected from carboxylic acids comprising at least one heteroatom in addition to the carboxylic group.
