[0001]

TECHNICAL FIELD The present invention relates to a hair treatment agent such as a hair rinse, a hair conditioner and a hair treatment.

[0002]

2. Description of the Related Art Hair treatment agents such as hair rinses, hair conditioners, and hair treatments have hitherto been used in combination with a cationic surfactant and silicone to soften the hair with the cationic surfactant and to comb the hair. The surface of the hair is smoothed with silicone to impart gloss to the hair and prevent split ends due to combing (for example, JP-A-63-22).
2109).

[0003]

However, only with the above-mentioned device, the surface properties of the hair are modified, and the protein component of the hair is eluted by washing the hair to cause damage to the hair. As a result, the moisturizing ability of the hair is deteriorated, and when the hair becomes dry, it cannot be eliminated.

[0004] Therefore, an object of the present invention is to provide a hair treatment agent capable of eliminating damage to hair due to washing hair, deterioration of moisturizing property and generation of dryness.

[0005]

The present invention has achieved the above object by incorporating a quaternary ammonium derivative of an animal protein-derived peptide, a cationic surfactant and silicone into a hair treatment agent. It is a thing.

That is, a quaternary ammonium derivative of an animal protein-derived peptide protects the hair, penetrates into the hair to enhance the moisturizing properties of the hair, and keeps the hair moisturizing and luster for a long time. Since the excessive adsorption of the cationic surfactant is prevented, the hair damage due to the excessive adsorption of the cationic surfactant is prevented.

The quaternary ammonium derivative of the animal protein-derived peptide that penetrates into the hair and retains its moisturizing property is covered with a film of silicone or a cationic surfactant to prevent its outflow. The quaternary ammonium derivative of the sex protein-derived peptide is not lost by washing the hair and protects the hair for a long time, and the moisturizing property of the hair is maintained for a long time.

In addition to the above-mentioned action, the cationic surfactant has its own action, is adsorbed to the hair to soften the hair, improve the combability of the hair, and prevent the hair from being charged. Silicone also smoothes the surface of hair,
It imparts luster and luster to the hair, improves the ability to pass through the hair, and prevents split ends due to combing.

In the present invention, as described above, the quaternary ammonium derivative of the animal protein-derived peptide, the cationic surfactant and the silicone are contained as essential components in the hair treatment agent. Is the street.

[Table 3]

As described above, the peptide of the quaternary ammonium derivative of the animal protein-derived peptide represented by the general formula (I) is a naturally occurring animal protein, for example, collagen or its modified product gelatin, keratin, It can be obtained by hydrolyzing proteins such as silk, casein, egg yolk, and egg white with acids, alkalis, enzymes, etc., but during the hydrolysis, the amount of acid, alkali, enzyme added, reaction temperature, reaction time, etc. By appropriately selecting, the value of n of the obtained animal protein-derived peptide can be made to be a preferable value of 2 to 30, that is, a molecular weight of about 200 to about 4500 (when the value of n is small, it happens to be the molecular weight. Of small amino acids
When n = 2, the molecular weight may be about 200.
When the value of is large, it is not considered that only the amino acids with small molecular weight are lined up, and the amino acids with large molecular weight are also included. Therefore, when n = 30, the molecular weight is about 45.
It may be 00).

Upon acid hydrolysis of animal protein,
For example, inorganic acids such as hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid and hydrobromic acid, and organic acids such as acetic acid and formic acid are used.

In alkali hydrolysis, an inorganic alkali such as sodium hydroxide, potassium hydroxide, lithium hydroxide, barium hydroxide, sodium carbonate, potassium carbonate or lithium carbonate is used.

For the enzymatic hydrolysis, acidic proteolytic enzymes such as pepsin, proctase A and proctase B, and neutral or alkaline proteolytic enzymes such as papain, bromelain, thermolysin, trypsin, pronase and chymotrypsin are used. It In addition, fungal neutral or alkaline proteolytic enzymes such as subtilisin and staphylococcus protease can also be used.

The quaternary ammonium derivative of the animal protein-derived peptide represented by the above general formula (I) has a quaternary ammonium group at the terminal amino group of the animal protein-derived peptide obtained by the above hydrolysis. It has been transformed into
Due to the quaternization, the property of adsorbing to hair is further enhanced, and the action of the animal protein-derived peptide is more remarkably exhibited.

Specific examples of the quaternary ammonium derivative of the animal protein-derived peptide represented by the general formula (I) include, for example, the animal protein-derived peptide caprylyldimethylammonio-2-hydroxypropyl. Derivatives, capryl dimethylammonio-2-hydroxypropyl derivatives, lauryl dimethylammonio-

The content of the quaternary ammonium derivative of the animal protein-derived peptide in the hair treatment agent is preferably 0.5 to 5% by weight, more preferably 0.5 to 2% by weight.

That is, when the content of the quaternary ammonium derivative of the animal protein-derived peptide in the hair treatment agent is less than the above range, the hair is protected, the moisturizing property of the hair is enhanced, and the cationic interface is used. The effect of preventing excessive adsorption of the active agent cannot be sufficiently exhibited, and even if the content of the quaternary ammonium derivative of the animal protein-derived peptide in the hair treatment agent exceeds the above range, the effect is not exerted. No increase is seen and there is a risk that the hair will remain sticky and sticky.

The cationic surfactant is adsorbed to the hair to soften the hair, improve combability of the hair, prevent static charge on the hair, form a film on the hair, and penetrate into the hair. It is prevented from being lost by the quaternary ammonium derivative of the animal protein-derived peptide, and the moisturizing property of the quaternary ammonium derivative of the animal protein-derived peptide is maintained for a long period of time to keep the hair moisturized for a long time. Make it lean.

Specific examples of such a cationic surfactant include, for example, stearyltrimethylammonium chloride, cetyltrimethylammonium chloride, cetostearyltrimethylammonium chloride, stearylbis (diethyleneglycol) hydroxyethylammonium chloride, behenyltrimethylammonium chloride and odor.

The content of these cationic surfactants in the hair treating agent is preferably 0.2 to 5% by weight, more preferably 0.5 to 2% by weight. That is, when the content of the cationic surfactant in the hair treatment agent is less than the above range, those effects cannot be sufficiently exhibited, and in the hair treatment agent of the cationic surfactant. When the content of the above is more than the above range, the amount adsorbed to the hair becomes too large, and the hair becomes extremely soft, which causes inconvenience to the touch, elution of the hair protein component and deterioration of the moisturizing property of the hair. May cause dryness of hair.

The silicone smoothes the surface of the hair, imparts luster and luster to the hair, improves combability of the hair, prevents split ends due to combing, and, like the cationic surfactant, silicone. A film is formed on the top of the hair to prevent the quaternary ammonium derivative of the animal protein-derived peptide that has penetrated into the hair from being lost by washing the hair.
