[0002]

2. Description of the Related Art In recent years, the trend of morning shampoos and the increasing use of hair shampoos every night have been accompanied by a large number of shampoos that have less dryness, are soft and moisturized, and give a smooth and light finish after use. It has come to be used.

Many of these shampoos reduce the activity of relatively strongly irritating surfactants such as alkyl sulphates or polyalkyl ether sulphates, or use less irritating surfactants at all. Further, a cationic surfactant is added to give a soft and moist feeling (for example, JP-A-52-66506).

[0004]

However, with only the above-mentioned measures, the sebum component of hair is degreased by repeated use for a long period of time or excessive washing, and excessive adsorption of the cationic surfactant occurs. , Elution of protein components, deterioration of moisture retention, and dryness of hair will occur.

Therefore, an object of the present invention is to provide a shampoo which prevents damage to the hair due to repeated washing and the like and has a good conditioning action on the hair.

[0006]

The present invention provides a quaternary ammonium derivative of an animal protein-derived peptide other than collagen, an amino acid-based anionic surfactant, or an acylated product of an animal protein-derived peptide or a salt thereof. The above object is achieved by incorporating a cationic surfactant into the shampoo.

That is, as the main component for exerting the detergency, an amino acid type anionic surfactant or an acylated product of an animal protein-derived peptide or a salt thereof, which has a low protein denaturing effect and is mild, is used and collagen is used. The use of a quaternary ammonium derivative of an animal protein-derived peptide other than the above protects the hair, enhances the moisturizing properties of the hair, and prevents excessive adsorption of the cationic surfactant to the hair.

Then, by the cationic surfactant,
It is intended to enhance the conditioning effect on the hair such as softening the hair and to retain the moisturizing property of the quaternary ammonium derivative of the animal protein-derived peptide other than collagen for a long period of time.

However, when the value of n is large, it is not considered that only amino acids with small molecular weights are lined up. Since the incoming also large amino acid of the amount, there is the molecular weight of about 4500 at the time of the n = 30).

For acid hydrolysis of animal proteins other than collagen, for example, hydrochloric acid, sulfuric acid, phosphoric acid, nitric acid,
Inorganic acids such as 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.

In the enzymatic hydrolysis, for example, 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 other than collagen represented by the general formula (I) is a terminal of the animal protein-derived peptide other than collagen obtained by the above-mentioned hydrolysis. Is a quaternized amino group of which the property of adsorbing to hair is further enhanced and the action of an animal protein-derived peptide other than collagen is more remarkably exhibited.
