Abstract

PURPOSE:To provide a composition for hair capable of highly preventing the discoloration of a polyphenol compound and useful as the second liquid of a hair-dyeing agent by comprising the polyphenol compound and a nitrogen- containing compound and further to provide a composition for the hair useful as a foamable hair-treating agent by comprising the polyphenol compound and a nonionic surfactant. CONSTITUTION:A composition for hair comprises a polyphenol compound (e.g., pyrogallol, resorcinol or catechol) and a nitrogen compound (e.g., a neutral hydroxyamino acid such as threonine or serine or a neutral imino acid such as proline). The composition can prevent the oxidative coloration of the polyphenol compound, thereby suitable as the second liquid of a hair-dyeing agent comprising the first liquid containing a polyvalent metal salt and the second liquid containing the polyphenol compound. A composition for the hair comprises the polyphenol compound and a nonionic surfactant (e.g., polyoxyalkylene alkyl ether). The composition provides foams having good texture and stability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair composition containing a polyphenol compound, and more specifically, a composition for hair that is suitably used as a hair dye or foam hair treatment agent. Regarding the composition.

[Problems to be solved by conventional techniques and inventions] Conventionally,
Many hair dyes that contain paraphenylenediamine-based oxidized dyes as the main ingredient are often used, but these hair dyes may cause skin irritation or allergies in some people, or There are safety issues, such as doubts about the mutagenicity of hair, and hair is damaged by alkali and oxidation treatments. For this reason, hair dyes that are safe for the human body have been formulated with amino acids and keratin hydrolysates or collagen hydrolysates (Japanese Unexamined Patent Application Publication No. 1983-1999).
-78915 Publication), Chinoku Special Publication using a combination of alkali metal salt, casein, amylase and glycine
Although various hair dyes have been proposed, such as those in which dihydroxyacetone is combined with a nitrogen-containing compound such as an amino acid or a peptide, none of these products have sufficient hair dyeing properties.

On the other hand, as a hair dye that is safe for the human body and has relatively good hair dyeing properties, the
and a second liquid containing a polyphenol compound are known (JP-A-61-20523 and JP-A-61-55483). This hair dye forms a colored complex through a reaction between a polyvalent metal salt and a polyphenol compound by sequentially applying a first liquid and a second liquid to the hair.

However, polyphenol compounds are susceptible to heat and
Therefore, the second liquid hair dye containing the polyphenol compound changes color significantly during storage, reducing its commercial value. For this reason, in order to prevent discoloration, it has been conventional practice to fill an opaque container with a second liquid hair dye containing a polyphenol compound.
This method does not provide a sufficient effect of preventing discoloration.

Moreover, the hair dye composed of the first liquid and the second liquid is not yet fully satisfactory in terms of hair dyeing properties.

On the other hand, foamy hair treatment agents, such as foamy hair styling products, permanent waves, hair colors, etc., have been widely used in recent years. These foam hair treatment agents are those in which the treatment agent is ejected in a foamed state from an aerosol container filled with the liquid treatment agent. In this case, various surfactants are usually used to make the processing agent foamy (for example, Japanese Patent Publication No. 39-2
No. 229, Special Publication No. 1973-28649, Special Publication No. 1977-3
No. 7291, JP-A-48-38286, JP-A-57-
No. 15147, JP-A-51-22832, JP-A-51-115154 using POE nonylphenyl ether
No., POE castor oil-induced oil conductor JP-A-53-860
44, JP 53-101543 using amide, JP 56-63914 using amide and POE nonionic surfactant, JP 58-189106, etc.).

However, as described above, when foam is formed using a surfactant, the texture and stability of the foam are poor, resulting in poor usability. It has also been proposed to use surfactants in combination with higher alcohols, cationic polymeric substances, nonionic polymeric substances, etc. for the purpose of improving foam stability.
It is difficult to obtain satisfactory foam texture and foam stability by this means.

The present invention was made in view of the above circumstances, and provides a hair dye composition that has good hair dyeability and does not change color over time, and a foam hair composition that has good foam texture and foam stability. An object of the present invention is to provide a hair composition containing a polyphenol compound that can be suitably used as a treatment agent.

[Means and effects for solving the problems] In order to achieve the above objects, the present invention provides a hair composition (hereinafter referred to as the first composition in some cases) containing a polyphenol compound and a nitrogen-containing compound.

The present invention also provides a hair composition (hereinafter referred to as a second composition in some cases) containing a polyphenol compound and a nonionic active agent.

In the first composition, by using the polyphenol compound and the nitrogen-containing compound in combination, the polyphenonyl compound is effectively prevented from being oxidized and overlaid. Therefore, the present composition contains a polyvalent metal salt. The second part of the hair dye consists of a first part containing a polyphenol compound and a second part containing a polyphenol compound.
It is preferably used as a liquid. Furthermore, when the composition of the present invention is used as the second liquid of the hair dye, the hair dyeing properties are improved. The reason why the anti-fogging properties and hair dyeing properties are improved in this way is not necessarily clear, but it is speculated that the anti-fogging properties are caused by the incorporation of polyphenol compounds into nitrogen-containing compounds and the prevention of oxidation of the polyphenol compounds. It is thought that this is due to the fact that the hair dye properties are fixed on the surface or inside of the hair, and it is thought that this may mediate the bond between the hair and the colored metal complex.

On the other hand, in the second composition, the foam-forming effect of the nonionic active agent is improved by using the polyphenol compound and the nonionic active agent in combination, and therefore, the present composition is suitably used as a foamy hair treatment agent. Foam texture and foam stability can be improved.

The present invention will be explained in more detail below.
