Description

Hair dye mixture containing monomer Technical field

The present invention relates to a hair dye mixture comprising a monomer and an oxidation dye precursor.

Background technique

The chemical modification of the inner region of the hair shaft portion has been disclosed in the prior art. Patent documents WO2009/088520A, WO2012/100006A, WO2012/100007A, EP2772246A1 and EP2295029A describe the use of ethylene monomers to chemically modify the inner region of the hair shaft region - in particular, ethylene molecules can be attached to the hair and/or in the hair and other The ethylene molecules are joined to form macromolecules, such as polymers. This can increase the hardness of the hair by modifying the internal structure of the hair shaft, which can provide advantages for hair styling, such as easy styling, or increase hair volume and longer styling time. The potassium 3-sulfonate methacrylate (3-SPA) is a monomer used to chemically modify the inner region of the hair shaft and has a molar mass of M.Wt. 232.2 g/mol. No. 3,472,243 discloses the process of straightening and conditioning hair by polymerizing a water-soluble monomer in the hair which is an acid-containing vinyl compound which is linked by a bridging agent to reduce its water solubility.

Hair dyeing or coloring is the use of hair dyes on the hair to color the hair. The hair color of the entire head can vary slightly or significantly. The roots are dyed to match the color of the rest of the hair. And the effect of shining, highlighting the hair bundle or area hair, or updating the same color for the fading and/or color wash off. The reason for hair dyeing may be just seasonal changes - many female customers want the color of their hair to be lighter in the summer, so that it can set off the color of the skin after sun exposure - or just for the mood, image, wearing Or a change in hair style. For a slightly older client, whitening of the hair is a major concern and encourages frequent use of hair root polish. Today, customers (whether at home or in the hair salon) are using a direct hair dye that can be washed off relatively quickly, using a sparkling effect, and highlighting the dyeing technique relative to conventional (semi) holdings, or accelerating the color developer, such as

Perfect 10, there are a wide range of options.

A common drawback of traditional hair dyeing is damage to the hair structure. Many customers are concerned about excessive handling of hair, and professional stylists in hair salons oppose further chemical treatments such as curling, bleaching, or permanent dyeing, which can over-dry or split the hair. Damaged hair may be more difficult to shape and manage - For example, dry hair is easy to fly and easy to roll. Hair splitting and drying affect the hair microstructure, resulting in irregular stratum corneum spacing. At the microscopic level it can be considered as reduced hair brightness.

As a result, there is a need to provide an improved hair coloring mixture, especially a hair coloring agent that improves hair health.

Summary of the invention

The above drawbacks can be overcome by the following hair dye mixture, a hair dye mixture containing the following ingredients:

a weight content of from 1 to 15% by weight of the monomer having the following chemical formula:

H ₂ C=C(X)-C(=O)OR ^a OH

Wherein X is hydrogen or CH ₃ , R ^a is an alkyl group, and the monomer has water solubility;

An oxidant dye precursor comprising at least one couplant and at least one primary intermediary;

Wherein the mixture has a pH of 8 to 12 and is free of oxidizing agents.

Another aspect of the invention is a hair oxidative colorant mixture comprising a monomer having a molecular weight of less than 200 g/mol and wherein the monomer has the formula:

H ₂ C=C(X)-C(=O)ORaOH

Wherein X is hydrogen or CH ₃ , Ra is a C1 to C4 alkyl group, and the monomer has a water solubility which has a particular advantage.

Further, the present invention relates to a kit for hair coloring, comprising: any one of the above-described mixtures; and an oxidizing formulation containing an oxidizing agent, wherein the mixture is packaged separately from the oxidizing formulation.

The invention further relates to a method of dyeing hair comprising mixing the above mixture with an oxidizing formulation comprising an oxidizing agent to form a mixture, and applying the mixture to the hair.

The invention further relates to a hair dye formulation ready for use, comprising:

a monomer having a weight percentage between 1.0 wt% and 5 wt%, and the monomer has the formula: H ₂ C=C(X)-C(=O)OR ^a OH; wherein X is hydrogen or CH ₃ , R ^a is a C1-C4 alkyl group, and the monomer has water solubility;

An oxidative dye precursor having at least one couplant and at least one primary intermediary;

- an oxidizing agent;

Wherein the mixture has a pH of from 8 to 12.

It has been observed that (meth) acrylate is a nucleophilic reagent at high pH, so it can participate in the addition reaction of the coupler with the primary intermediary as well as the nucleophile, thereby hindering one dye reaction pathway and promoting another fuel. Reaction pathway. In general, the dye enters the hair faster than the reaction speed between the dyes. In the presence of (meth) acrylate, we observed that there is no chromatic aberration in the ring dye, which means that the same color is produced at a faster rate, and the dye reacts faster than it penetrates. This allows the dye to be more concentrated around the hair shaft, allowing the customer to feel the dyeing deeper.

The advantages of the present invention over the prior art are:

- low dye demand;

- stronger dyeing effect;

- no color difference;

-cut costs;

- less exposure to dyes;

- The ring dye effect on the cut surface of the hair shaft.

The details of the invention and the preferred details are set forth below:

The first aspect of the invention is a "dyeing agent mixture", referred to as a "mixture." The mixture is used for dyeing hair and is a mixture for mixing, that is, for mixing with an oxidizing formulation to provide a mixture, i.e., the "hair dye formulation ready for use".

In at least one embodiment, the mixture is a liquid. Liquid mixtures are very useful because they are easily mixed with oxidizing formulations which are also usually liquid.

Wherein X is hydrogen or CH ₃ , Ra is a C1-C4 alkyl group, and the monomer has water solubility. The monomer contains a vinyl group. The monomer contains an acrylate or methacrylate group. Acrylate refers to H ₂ C=CH-C(O)O ^- . The methacrylate group refers to H ₂ C=C(CH ₃ )-C(O)O ^- .

In at least one embodiment, the monomer contains the following chemical formula

H ₂ C=C(CH ₃ )-C(=O)OR ^a OH

Wherein R ^a is an alkyl group and the monomer has a molecular weight of less than 200 g/mol. In at least one embodiment, the mixture of the invention has a monomer weight percentage of from 0.1 to 15%, alternatively from 0.1 to 10%, or from 1 to 5%.

A proton is emitted to the free radical of the ethylene monomer. The resulting compound cannot be polymerized because it no longer has free radicals. The butyl group on the polymerization inhibitor serves as an electron donating group for stabilizing the radicals formed in the benzene ring.

In at least one embodiment, the mixture is substantially free of any initiator for free radical polymerization. An advantage of the mixture being substantially free of any free radical polymerization initiator is that the risk of the monomer self-polymerization can be reduced.
