Description

[Detailed description of the invention] 1 boat [Industrial application field 1 The present invention relates to a powdered hair dye composition.

[Conventional technology] Powdered hair dye (Yoto Wet and Temperature) Dissolve in a liquid such as a diluted solution to make a viscous paste hair dye, and then use it with a brush or a brush.
It is applied to the hair by hand.

There are two types of oxidation dyes: one-dose type, in which a powdered oxidation dye and a powdered oxidizing agent are mixed together in one package, and a liquid such as water is added just before use to adjust the hair dye solution; A two-pack type in which the liquid and oxidizing agent are packaged and mixed with the liquid just before use, and a type in which the powdered oxidation dye is packaged in one package and the liquid in which the oxidizing agent is dissolved is mixed to make a hair dye liquid. etc. are known.

Since all or the main components of the hair dye 1 are in powder form, manufacturing control and transportation are easy, and the method of use is also simple. Furthermore, it has the advantage of being able to be used in small portions and being lightweight and convenient to carry. Therefore, it is more desirable in the market than liquid hair dyes.

[Problems to be Solved by the Invention] However, conventional powder hair dyes have the disadvantage that the hair becomes dry after dyeing and the finish of the hair is not good.To improve this 1:.

Although it has been proposed to incorporate an oil component, this creates a new problem of reducing the stability of other components, such as dye components and oxidizing agents, and is not an effective solution.

Therefore, there was a need to improve the finish of hair without causing such drawbacks.Furthermore, conventional powder hair dyes still lacked sufficient fluidity properties, and improvements in these properties were also desired. Here, we refer to the flow characteristics and flow characteristics suitable for producing powdered hair dyes or for use in small portions, which is one of the features of such hair dyes.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a composition constituting a powdered hair dye that can finish hair in a good condition and has high stability, fastness, and flow characteristics.

The structure of the present invention that achieves the above object will be described below.

[Means and effects for solving the problems] The present invention is a powdered hair dye composition containing a powdered silicone compound.

The powdered hair dye composition of the present invention having the above-mentioned structure (as evidenced by the Examples below) provides a good finish to the hair and has both fastness and hair dyeing power higher than conventional compositions. Powdered silicone compounds (
It is a compound with low reactivity and hardly impairs the stability of other components contained in the powder composition. Furthermore, such a hair dye composition has appropriate fluidity characteristics and is easy to dispense and measure when used in small portions. This is because powdered silicone itself has excellent flow characteristics.

The present invention will be explained in more detail below.

The powdered hair dye composition of the present invention (which may constitute any type of powdered hair dye; therefore,
Powdered powder containing all or at least some of the components that contribute to hair dyeing (i.e., color-forming compounds that exhibit the color as a hair dye during hair dyeing or precursor components of such compounds). The composition is mixed with a liquid agent (e.g., water) that functions only as a solvent when used, or a liquid agent containing a component (e.g., an oxidizing agent) that converts the precursor into a color-forming compound. Be that as it may be (dai)
It can be of any kind. In addition, the form of the powdered hair dye composition of the present invention (1) may be in a state in which all the components are mixed together, or may be divided into two or more powder groups.

It is typically a combination of a compound that is oxidized and causes a coupling coloring reaction (hereinafter referred to as an oxidation dye intermediate) and a compound that becomes a coupler for this compound.

As its oxidation dye intermediates (such as ['L Phenylenediamines, aminophenols, toluylenediamines, aminonitrophenols, diphenylamines, diaminophenylamine kai N-phenylphenylenediamine Sagi, diaminopyridines and their salts), One type or a mixture of two or more types can be used.

As a coupler, E-resorcinol, pyrogallol, catechol, meta-aminophenol, meta-phenylenediamine, etc. can be used.

The molar ratio between the oxidation dye intermediate and the coupler may be appropriately selected depending on the coupling color reaction.

The oxidizing agent for oxidizing the above-mentioned oxidation dye intermediate may or may not be included in the composition of the present invention; For example, +f as this oxidizing agent.

Sodium perborate, urea peroxide, melamine peroxide.

Examples include sodium sulfate/hydrogen peroxide adduct, sodium pyrophosphate/hydrogen peroxide adduct, dibasic sodium phosphate/hydrogen peroxide adduct, and sodium percarbonate.

In addition to the above-mentioned ingredients, ingredients that contribute to hair dyeing include, for example, the ``Standards for Hair Dye Raw Materials'' (Revised Third Edition, May 1985).
