Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair treatment composition, and more particularly to a hair treatment composition which imparts long-lasting softness to hair and exhibits an excellent decolorizing effect.

[0002]

2. Description of the Related Art When a hair dryer, a perm, or a hair dye is applied to the hair, it is physically and chemically damaged, resulting in dryness, split ends, etc. Be spoiled. Therefore, conventionally, various hair treatment compositions such as hair rinses and hair treatments have been developed in order to prevent such damage to hair or to repair damaged hair by restoring it to a normal state. It is in practical use.

[0003] In most of them, a hair-modifying component such as a cationic surfactant typified by a quaternary ammonium salt, a cationic polymer or a polymer latex is adsorbed on the surface of the hair, or an amino acid or the like is adsorbed inside the hair. Although it is intended to protect or improve the hair by infiltrating it into the skin, there is a problem that the effect is not sustainable.

Modified silicone containing a thiosulfate group (hair-modifying component) for providing a long-lasting repair to damaged hair
Although a composition in which
(JP-A-4-66519), in this composition, the hair modifying component does not penetrate into the deep part of the hair and does not act on the deep part of the hair, so that it is not possible to impart temporary flexibility to the hair. However, there is a problem that it is not possible to impart durable flexibility, and the decolorizing effect by the oxidizing agent is still insufficient.

As a result of intensive studies, the present inventors have found that the specific quaternary ammonium salt as a hair-modifying component is used in combination with a keratin-oxidizing substance and a specific organic solvent. It was found that the hair treatment composition can rapidly and deeply penetrate deep into the hair and can impart excellent flexibility to the hair for a long period of time, and that it can provide an excellent bleaching effect. .

The present invention has been made on the basis of such findings, and an object of the present invention is to provide a hair treatment agent which imparts long-lasting and excellent softness to hair and exhibits an excellent decolorizing effect. Providing a composition.

[0007]

A hair treatment composition according to the present invention for achieving the above object comprises 0.01 to 15% by weight of a keratin-oxidizing substance (A) and a compound represented by the following chemical formula 1. Contains 0.01 to 10% by weight of a quaternary ammonium salt (B) and 0.5 to 50% by weight of an organic solvent (C) composed of a monohydric aliphatic alcohol and / or aromatic alcohol having 5 to 8 carbon atoms. I will do it.

[0008]

Specific examples of the keratin-oxidizing substance (A) in the present invention include peroxides such as hydrogen peroxide, sodium percarbonate and sodium perborate; and bromates such as sodium bromate and potassium bromate. To be done.

Of these, hydrogen peroxide and sodium bromate are preferable because of their high permeability promoting effect and flexibility imparting effect.

Keratin Oxidizing Substance (A) in the Present Invention
The above may be used alone or in combination of two or more as required.

The amount of the keratin oxide (A) used in the present invention is 0.01 to 15% by weight, preferably 1.0 to 10% by weight, based on the total amount of the composition. If the amount is less than 0.01% by weight, the effect of promoting permeability, the effect of imparting flexibility and the decolorizing effect are not sufficiently exhibited, while if the amount is more than 15% by weight, the hair may be damaged. There is.

The quaternary ammonium salt (B) according to the present invention may be used alone, and if necessary, 2
You may mix | blend combining more than 1 type.

The amount of the quaternary ammonium salt (B) used in the present invention is 0.01 to 0.01 based on the total amount of the composition.
It is 10% by weight, preferably 0.1 to 7% by weight. When the amount is less than 0.01% by weight, the effect of imparting flexibility is not sufficiently exhibited, while when the amount is more than 10% by weight, the flexibility improving effect corresponding to the increase cannot be obtained. Not only that, but it becomes more irritating to the skin.

The organic solvent (C) in the present invention comprises a monohydric aliphatic alcohol and / or aromatic alcohol having 5 to 8 carbon atoms.

The monohydric aliphatic alcohol may be either a linear alcohol or a branched alcohol, or a saturated alcohol or an unsaturated alcohol. As the monohydric aliphatic alcohol having 5 to 8 carbon atoms, 1

The aromatic alcohol is a saturated alcohol or an unsaturated alcohol having an aromatic ring. As the aromatic alcohol, benzyl alcohol, 2-phenylethanol, cinnamic alcohol, phenylpropanol, phenoxyethanol, dimethylbenzylcarbinol,
Examples are benzyloxyethanol, tolyl alcohol and α-methylbenzyl alcohol.

As the organic solvent (C) in the present invention,
Since 1-pentanol, 2-pentanol, 3-pentanol, hexanol, 2-phenylethanol, cinnamic alcohol, phenylpropanol, α-methylbenzyl alcohol, phenoxyethanol, and dimethylbenzylcarbinol have high penetration promoting effects, Particularly preferred.

The organic solvent (C) used in the present invention may be used alone or in combination of two or more as required.

The content of the organic solvent (C) in the present invention is 0.5 to 50% by weight, preferably 1.0 to 20% by weight, based on the total amount of the composition. If the amount is less than 0.5% by weight, the effect of promoting permeability is not observed, while if the amount is more than 50% by weight, the stability of the agent as a composition deteriorates.

The hair treatment composition according to the present invention is a one-component hair treatment composition containing all of a keratin oxide substance (A), a quaternary ammonium salt (B) and an organic solvent (C) in one agent. The composition may be a two-component hair comprising a first liquid containing a keratin-oxidizing substance (A) and a second liquid containing a quaternary ammonium salt (B) and an organic solvent (C). It may be a treating agent composition. When this type of two-part hair treatment composition is used, the hair can be efficiently imparted with flexibility.

In addition, if necessary, the hair treatment composition of the present invention may further contain an oil component, a colorant, and a quaternary ammonium salt represented by the above chemical formula 3 as long as the performance thereof is not impaired. You may mix | blend a conventionally well-known component for hair treatment agents, such as a surfactant, a pH adjuster, a metal blocking agent, a fragrance | flavor, water, and ethanol.

The hair treatment composition according to the present invention can be produced by a conventional method and can be made into various forms such as liquid, emulsion, cream and foam, and rinse, treatment, hair cream and hair blow. As such, it can be applied to the hair by conventional usage.
