DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic which is non-greasy, imparts an excellent setting force and suppresses flaking.

[0002]

2. Description of the Related Art Heretofore, carrageenans widely used have been a single kind of carrageenan called κ-carrageenan, ι-carrageenan and λ-carrageenan. When these carrageenans are used in cosmetics, there are drawbacks in that the viscosity changes drastically with changes in temperature (viscosity characteristics) and that the sol-gel state changes. For this reason, the performance and feeling of use of the cosmetics differ between cold and warm regions, or between summer and winter, and there are problems in quality and performance. Also,
When conventional carrageenan is applied to hair alone and dried,
Flaking was likely to occur, and the appearance was not very favorable.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hair cosmetic which overcomes the above-mentioned drawbacks of a hair cosmetic using a single kind of carrageenan, is non-greasy and imparts an excellent setting force. It is in.

[0004]

Under such circumstances, the present inventors have conducted intensive studies. As a result, when a carrageenan containing κ-carrageenan and λ-carrageenan in an arbitrary ratio in a single chain is used, the above viscosity characteristic is obtained. It has been found that, when this is combined with silicone or a derivative thereof, a hair cosmetic that is non-sticky and imparts an excellent setting power can be obtained, and has completed the present invention.

That is, the present invention provides a hair cosmetic containing carrageenan containing κ-carrageenan and λ-carrageenan in a single chain.
