Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a powdered oxidation hair dye, and more specifically, it has excellent flow characteristics when dissolved in water during use, and has good durability after hair dyeing. This invention relates to a powdered oxidative hair dye with excellent properties and hair finish.

[Prior art and its problems] Powdered oxidation hair dyes are usually prepared by mixing a powdered oxidation dye and a powdered oxidizing agent into a package, and adding a liquid agent just before use to prepare a hair dye solution. A one-dose type, a two-dose type that contains a powdered oxidation dye and a powdered oxidizing agent, and a two-dose type that contains a powdered oxidized dye and a liquid oxidizing agent and mixes it immediately before use to prepare a hair dye solution. Two-component powder hair dyes are known. Since all of these powdered oxidation hair dyes are in powder form,
In some respects, it is more desirable than liquid hair dye because it has the advantages of being easy to manage and transport, easy to use and can be used in small doses, and lightweight and convenient to carry. It's something. When using powdered oxidation hair dye, dissolve it in water, warm water, or an appropriate diluent immediately before use to prepare a viscous paste-like hair dye, and then apply it with a brush, brush, or hand. It is necessary to apply it to the hair, but in this case it is desirable that the hair dye has an appropriate viscosity.

Therefore, conventionally, in order to adjust the viscosity of hair dye solutions, methods have been adopted in which, for example, natural polymers such as starch, semi-synthetic polymers such as carboxymethyl cellulose, and synthetic polymers such as polyvinyl alcohol are blended.

However, in this method, although the viscosity of the hair dye solution when applied can be adjusted appropriately, the viscosity when the powdered oxidized hair dye is first dissolved in water etc. also becomes high, making it difficult to dissolve the powder components uniformly. The disadvantage is that it is difficult to On the other hand, if the solubility at the initial stage of dissolution is improved, the viscosity at the time of application will be low, and the disadvantage is that the hair dye solution will drip from the hair during hair dyeing or after the hair dyeing process, contaminating the skin and scalp. be.

Powdered oxidation hair dyes are also required to have better fastness after dyeing and to give a good finish to the hair.

[Problems to be solved by the invention and means for solving the problem] In view of the above circumstances, the present inventor has developed a powdered oxidation hair dye in which the powder component can be easily and uniformly dissolved in water etc., and the hair dye solution has an appropriate viscosity when applied. As a result of intensive studies to obtain this, we found that by blending quaternary nitrogen-containing cellulose ether and polypeptide, the viscosity at the initial stage of dissolution is low, and the powder components can be uniformly dissolved.
Thereafter, they discovered that the viscosity of the hair dye solution gradually increased and that appropriate viscosity could be obtained during application, and the present invention was completed.

In short, in the case of the present invention, hair can be dyed using a uniformly dissolved hair dye solution with an appropriate viscosity, so it has excellent spreadability, easy application, level dyeing, and straightness of sagging, and the polypeptide is It penetrates and adsorbs into the damaged areas of the hair, and since the quaternary nitrogen-containing cellulose ether forms a film on the hair surface, it retains the pigment that has penetrated into the hair well, resulting in excellent fastness. be.

That is, the gist of the present invention resides in a powdered oxidative hair dye characterized by containing a quaternary nitrogen-containing cellulose ether and a polypeptide.

In the present invention, a fourth dye is added to the powder oxidation hair dye as described above.
It is an essential requirement to blend a grade nitrogen-containing cellulose ether and a polypeptide. That is,
By the action of this compounding agent, the viscosity of the hair dye solution during dissolution and application can be adjusted appropriately, allowing for a good hair dye treatment.
