2. Description of the Related Art Conventionally, various techniques have been used to dye hair. Hair dyes that dye hair are generally classified into permanent hair dyes and temporary hair dyes. Permanent hair dyes are mainly for dyeing hair with an oxidative dye, and have very good hair dyeing properties, but the work is complicated and causes damage to the hair. On the other hand, the temporary hair dye is a method in which a dye is physically retained on the hair and the method of use is simple, but the hair dyeing operation requires repeated hair dyeing operations each time the hair is washed, and the hair dyeing property is It is inferior to permanent hair dyes. Further, this temporary hair dye has a problem that the dyed hair is easily transferred when it comes into contact with clothes or the like. For this reason, in recent years, semi-permanent hair dyeing by "color rinse" containing an acid dye has come to be touted. However, this color rinse is not very convenient for male consumers who are not in the habit of using the rinse. In addition, since such a color rinse tends to be manufactured by giving priority to storage stability, it is the current situation that the rinse effect and the prevention of dye stain on the skin are insufficient.

[0003]

In view of such circumstances, the present invention has an excellent hair-dyeing effect, has particularly good storage stability at high temperatures, and has excellent conditioning properties at the time of finishing, and skin. The purpose of the present invention is to provide a shampoo composition having low dyeability to.

[0004]

Means for Solving the Problems As a result of intensive studies on the shampoo composition exhibiting a hair dyeing effect, the present inventors have found that a betaine-type amphoteric surfactant and an acid dye having a sulfonic acid residue are used. By adjusting the pH in a specific range, the hair dye has an excellent hair dyeing effect due to an increase in the amount of dye adsorbed to the hair, good storage stability at high temperatures,
It was also found that excellent conditioning properties at the time of finishing can be obtained. Further, the present inventors have found that the characteristics of this shampoo composition are further improved by further adding an amino acid or an amino acid derivative to such a shampoo composition, and the present invention is based on this finding. It came to eggplant.

[0005] [Detailed Description of the Invention]

[0006]

That is, the present invention is
(A) 0.1-20% by weight of betaine-type amphoteric surfactant
And (B) an acid dye having a sulfonic acid residue of 0.01 to
The present invention provides a shampoo composition consisting essentially of an aqueous solution containing 2% by weight and adjusted to pH 2-5.

Further, according to the present invention, this aqueous solution preferably contains 0.1 to 20% by weight of at least one selected from the group consisting of amino acids and amino acid derivatives.

Suitable as the betaine-type amphoteric surfactant of the component (A) used in the present invention are amidobetaine-type amphoteric surfactants, alkylbetaine-type amphoteric surfactants, sulfobetaine-type amphoteric surfactants, and phosphonates. Examples include betaine-type amphoteric surfactants, imidazolinium-type amphoteric surfactants, and aminocarboxylic acid salt-type amphoteric surfactants. In the present invention, one type of these amphoteric surfactants may be used alone or two or more types may be used in combination.

Examples of the acid dye having a sulfonate residue used as the component (B) in the present invention include Black No. 401, Purple No. 401, Daidai No. 205, Red No. 106, Blue No. 1, Red No. 401. No., red 504,
Brown 201, green 3, yellow 5, yellow 203,
Blue No. 2, Red No. 102, Green No. 204 and the like can be mentioned. These can be used alone or in combination of two or more.

The shampoo composition of the present invention contains the component (A) in the range of 0.1 to 20% by weight, preferably 0.5 to 15% by weight, and the component (B) in the range of 0.01 to 2% by weight. Used. When the amount of the component (A) is less than 0.1% by weight, the storage stability at high temperature is lowered, the foaming, which is a characteristic feature of shampoo, is not good, and the conditioning property at the time of finishing is not good.

If the amount of the component (B) is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained. Furthermore, the amount of the component (A) and the amount of the component (B) are 20% by weight and 2%, respectively.
If the amount exceeds 5% by weight, not only the feeling of use and storage stability are not good, but also the dyeing of the dye on the skin cannot be prevented.

Further, in the shampoo composition of the present invention, an aqueous solution in which these components (A) and (B) are used in combination, and the pH of the aqueous solution containing both components is adjusted to the range of 2 to 5. Thus, for the first time, an excellent hair dyeing effect, storage stability at high temperature, conditioning property at the time of finishing, and low dyeing property to the skin can be obtained.

In adjusting the pH, one or more acids selected from organic acids and inorganic acids can be used. Specific examples of such an acid include citric acid, phosphoric acid, sulfuric acid, hydrochloric acid, malic acid, tartaric acid, gluconic acid, lactic acid, fumaric acid, and oxalic acid.

In the present invention, 0.1 to 20% by weight of one or more amino acids and amino acid derivatives are contained in addition to the above-mentioned essential components (A) and (B). The hair dyeing properties can be further improved and surprisingly good conditioning properties can be imparted to the hair.

Suitable as such amino acids and amino acid derivatives are one or more kinds of amino acids selected from neutral amino acids, acidic amino acids and basic amino acids and / or peptides, acylated amino acids and acylalkyl amino acids. One or more amino acid derivatives selected from the class.

More specifically, glycine, alanine, serine, glutamic acid, cystine, tyrosine, hydroxyproline and the like are preferably used as the amino acid. Examples of amino acid derivatives include hydrolyzed collagen, hydrolyzed keratin, acyl glutamate,
Acyl sarcosine salts, alaninates, and pyroglutamic acid derivatives are preferably used. In the present invention,
These amino acids and amino acid derivatives are used alone or in combination of two or more.

The acidic shampoo composition of the present invention contains, in addition to the above-mentioned essential components, within a range that does not impair the performance thereof.
If desired, an anionic surfactant, a cationic surfactant, a cationic polymer, a finishing performance imparting agent such as oil,
Thickener, UV absorber, preservative, emulsifier, appearance-imparting agent,
A bactericidal agent, an antioxidant, a tonic agent, a colorant other than the essential component (B) of the present invention, a fragrance, and a suitable solvent can be added.
