Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel hair cosmetic composition, more specifically, a shampoo, a hair rinse, which contains β-hydroxymonosulfonic acid or a salt thereof and has excellent long-lasting flexibility.
The present invention relates to hair cosmetics such as hair conditioners and hair treatments.

[0002]

2. Description of the Related Art Conventionally, for the purpose of improving the feel of hair, hair cosmetics have been known as mono- or di-linear long-chain alkyl quaternary ammonium salts and mono- or di-branched long-chain alkyl quaternary ammonium salts. And other cationic surfactants are blended.

However, although these conventional hair cosmetics are excellent in the feel of the hair, that is, a moist feeling as a conditioning effect, smoothness, etc., they have a drawback that they are insufficient in flexibility. That is, although the softness can be felt in the wet state, the effect is almost lost in the dry state. Therefore, in order to solve such a drawback, higher alcohols, glycerides, fats and oils such as liquid paraffin, and the like are used in combination. In these methods, by leaving hydrophobic molecules on the hair surface, the surface tension is lowered to impart a soft feeling to the touch, and the substances remaining on these hair surfaces come into contact with daily life over time. Alternatively, since it falls off due to the action of washing hair, it is difficult to maintain its effect in terms of flexibility. In addition, hard hair often has poor cohesion due to the large elasticity of the hair, and it has been difficult to meet the demands of consumers by conventional superficial measures. Recently, as a means for improving the flexibility of hair, the number of carbon atoms of 6 or more
Hair conditioning compositions using a combination of hydroxy fatty acid and a conditioning component have been proposed (for example, JP-A-3-48607 and 3-48609).
issue). However, even with the above means, the effect of sustaining the flexibility is not yet sufficient, and there is a problem that there is a problem such as smell and the amount used is limited.

[0004]

Accordingly, the hair is imparted with a moist feeling and smoothness, and at the same time, excellent flexibility,
Particularly, it has been desired to develop a hair cosmetic composition that can impart long-lasting and excellent flexibility to hard hair and that has good hair cohesion.

[0005]

[Means for Solving the Problems] Under the circumstances, the present inventors have conducted diligent studies to solve the above problems, and as a result,
By blending a specific amount of a β-hydroxymonosulfonic acid having 2 to 5 carbon atoms or a salt thereof, the hair can maintain the softness continuously, especially the hard hair can be kept soft, and the hair has excellent cohesiveness. The inventors have found that a cosmetic can be obtained and completed the present invention.

That is, the present invention has the following general formula (1):
