Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a high quality novel hair cleansing composition.

[0002]

2. Description of the Related Art In recent years, women's hair care behavior has diversified,
Hair care products having various functions have been put on the market. In the field of hair cleansing agents, an anionic surfactant is used as a main base, and a cationic polymer, a cationic surfactant, a silicone derivative, etc. are added to this to give a feeling of rinsing at the time of washing the hair and drying at the time of drying. Attempts have been made to improve the feel.

Alkyl sulfates, polyoxyethylene alkyl sulfates, α-olefin sulfonates and the like are the mainstream as anionic surfactants commonly used in hair cleansing agents. By using a cationic polymer such as a cationized cellulose, a cationized guar gum or a dimethyldiallylammonium / acrylamide copolymer in a hair cleansing agent containing these anionic surfactants, the feel at the time of rinsing can be improved. However, the dryness and dryness of the hair increased, which was unsatisfactory as the feel required by women for hair.

On the other hand, when a cationic surfactant such as an alkyltrimethylammonium salt or a dialkyldimethylammonium salt is used in combination with a hair cleanser containing these anionic surfactants, it is possible to slightly improve the dryness of the hair. However, an insoluble substance is generated due to charge cancellation of anion-cation, foaming is remarkably reduced, and the effect of the mixed cationic surfactant cannot be efficiently and sufficiently brought out.

Further, when a silicone derivative is used in combination with a hair cleansing agent containing the above-mentioned anionic surfactant, the dry feel and the smoothness are improved, but as the humidity decreases, the hair becomes dull and combs. When the hair is passed through with a hair brush or a hair brush, static electricity is generated and the hair spreads, that is, fly-away occurs, which makes it difficult to arrange the hairstyle.

[0006]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems found in conventional hair cleansing compositions, has good foaming, has a smooth feel during rinsing, and has no dryness during finishing. Further, it is an object of the present invention to provide a high-quality hair cleansing composition capable of preventing flyaway due to static electricity.

[0007]

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems that women demand for hair cleansing compositions, the present inventor found that a specific surfactant, amphoteric surfactant and branched chain fatty acid were used. Based on this finding, it was found that a composition containing a branched alcohol and / or a higher chain alcohol has good foaming properties, an excellent feel during rinsing and drying, and an effect of preventing flyaway due to static electricity. As a result, the present invention has been completed.

That is, according to the present invention, the following components A to
A hair cleansing composition comprising C is provided. A: One or more surfactants represented by the following general formula (1). B: One or more amphoteric surfactants. C: 1 of branched chain fatty acid and / or branched chain higher alcohol
Seed or two or more.
