Description

BACKGROUND OF THE INVENTION
The present invention, decolorizing and superior hair dyeing power, that good feel can be obtained de Iroyo products, and to a hair dyeing products.

[Prior art]
Conventionally, as a decoloring article, it consists of a first agent (bleaching agent) containing an alkaline agent and a second agent containing an oxidizing agent. During use, the first agent and the second agent are mixed. Two-component depigmenting products applied to hair have been widely used.

This decoloring article promotes the generation of oxygen from an oxidizing agent with an alkaline agent, decomposes the melanin pigment of hair with the oxygen, and decolorizes.
Further, the hair dyeing product comprises a first agent (hair dye) containing an oxidative dye intermediate and an alkali agent, and a second agent containing an oxidizer, and in use, the first agent and the second agent. Two-component oxidative hair coloring products that are mixed with an agent and applied to hair have been widely used.

When this oxidative hair coloring product is applied to hair, the above-mentioned decolorization is performed and hair is also dyed. In other words, the colorless low molecular weight oxidative dye intermediate contained in the first agent penetrates into the hair, and the oxidative dye intermediate is oxidatively polymerized by the action of the oxidant to produce a dye, so that the hair is dyed. Is done.

This hair dyeing product has a feature that it can dye hair in various colors according to demand.

[Problems to be solved by the invention]
However, since the decoloring product and the hair dyeing product obtain a decoloring power and a hair coloring power by the action of an alkali agent and an oxidizing agent, an alkaline agent or a hair coloring product is required to exert a sufficient decoloring power or hair coloring power. It is necessary to increase the blending amount of the oxidizing agent. In this case, problems such as skin irritation caused by the alkali agent or oxidizing agent, increased damage to the hair, and generation of an irritating odor have occurred.

The present invention has been made in view of the above, excellent decolorizing or dyeing power, it can be obtained a good feel of the hair, and further, has irritating odor is Na occur de Iroyo products, and hair goods The purpose is to provide.

[Means for Solving the Problems and Effects of the Invention]
Thus, as a result of intensive studies, the present inventors have completed the present invention by blending a nonionic surfactant, a higher alcohol, and an alkali agent each having an HLB within a predetermined range.
The decoloring article of the present invention is a decoloring article comprising a first agent that is a decoloring agent and a second agent that is an oxidizing agent, wherein the first agent and the second agent are mixed during use. 1 agent, a component a is a non-ionic surfactant, and the B component is a nonionic surfactant, and component C is a higher alcohol, containing, and the D component is an alkaline agent, wherein the component a , HLB is calculated from the equation of Griffin is, 3 to 9 Ri the range near, and a polyoxyethylene alkyl ether that having an alkyl chain of 12 to 22 carbon atoms, said component B, Griffin formula HLB calculated from the, 9 Ri greater range near, and a polyoxyethylene alkyl ether that having an alkyl chain of 12 to 22 carbon atoms, the amount of the B component relative to the amount of the component a The ratio is 0.0 In the range of 0.5, the total of the amount of the B component and the amount of the component A, for the entire first agent is in the range of 1 to 12 wt%, the dosage form is, The gist is a decolorizing article that is creamy, liquid, or jelly-shaped, and the second agent contains hydrogen peroxide as the oxidizing agent .
Further, the hair dyeing product of the present invention is a hair coloring product comprising a first agent that is a hair dye and a second agent that is an oxidizing agent, and the first agent and the second agent are mixed at the time of use. The first agent includes a dye, a component A that is a nonionic surfactant, a component B that is a nonionic surfactant, a component C that is a higher alcohol, and a component D that is an alkaline agent. The component A is a polyoxyethylene alkyl ether having an HLB calculated from the Griffin equation in the range of 3 to 9 and having an alkyl chain having 12 to 22 carbon atoms, and the component B Is a polyoxyethylene alkyl ether having an HLB calculated from the Griffin equation greater than 9 and having an alkyl chain having 12 to 22 carbon atoms, and the blending of the B component with respect to the blending amount of the A component Quantity The ratio is in the range of 0.05 to 0.5, and the sum of the blending amount of the component A and the blending amount of the component B is in the range of 1 to 12% by weight with respect to the entire first agent. The gist is a hair dyeing product characterized in that the dosage form is creamy, liquid, or jellyy, and the second agent contains hydrogen peroxide as the oxidizing agent.

Hereinafter, the decoloring product and the hair coloring product of the present invention will be described in more detail.
In the decoloring product and hair coloring product of the present invention, the first agent contains the A component, the B component, the C component, and the D component as described above, and the ALB and the B component have an HLB in the above range. Ah is, and a polyoxyethylene alkyl ether that having an alkyl chain of 12 to 22 carbon atoms, further, the ratio of the amount of the amount and the B component of the a component (wt% concentration), within the above range Therefore, the hair feels excellent after decoloring or hair dyeing (after plain rinsing and after drying). For example, even if hair is repeatedly decolored or dyed continuously. It has the feature that the feel of is good.

Therefore, when both the HLB of the A component and the HLB of the B component are in the range of 3 to 9 (outside the scope of the present invention), the decolorization effect and the hair dyeing effect are high, but the hair When both the ALB HLB and the BLB HLB are in a range greater than 9 (out of the scope of the present invention), the hair feels good, but decolorization occurs. The effect and hair dyeing effect are reduced.

Moreover, when the ratio (B / A) of the blending amount (weight% concentration) of the B component to the blending amount of the A component is smaller than 0.05, the decolorization effect and the hair dyeing effect are high, but the hair feel is poor. When the ratio (B / A) of the blending amount (weight% concentration) of the B component to the blending amount of the A component is greater than 0.5, the hair feels good, but the decoloring effect and the hair dyeing effect Becomes lower.

Furthermore, the 1st agent in the decoloring goods and hair coloring goods of this invention has the decoloring power and hair dyeing when the sum total of the compounding quantity of A component and the compounding quantity of the said B component exists in the range of 1 to 12 weight%.
