Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair setting composition, and more particularly, to a hair setting agent, a styling agent, a hair styling agent and the like having excellent set holding power and good feel without stickiness. The present invention relates to a hair setting composition.

[0002]

2. Description of the Related Art Hair setting agents which have hitherto been widely used are those in which a film-forming polymer compound is dissolved in water, a lower alcohol or a mixed solvent thereof. The polymer compound blended therein has an action of fixing the hairs to each other and holding the set, but the conventionally used ones have stickiness in the process of applying to hair and drying and finishing. , It wasn't smooth. In order to eliminate such drawbacks, attempts have been made to improve the feel of use by adding oils and fats for cosmetics, surfactants and the like to polymer compounds. However, a hair setting agent having both a satisfactory set holding power and a feeling of use has not yet been obtained.

In recent years, a hair treatment agent containing an amphoteric polymer compound and a cationic polymer (Japanese Patent Publication No. 2-4444).
No. 6, Japanese Patent Publication No. 3-14805) and a hair treatment agent containing an amphoteric polymer compound and an anionic polymer (Japanese Patent Publication No. 3-21524) have been developed. However, these treatment agents are not satisfactory in terms of non-greasiness and smoothness after application and drying, and also because the finished hair has a stiff feel.

Further, in recent years, a hair-setting composition containing carrageenan and an ethylene oxide-added nonionic surfactant, which is not sticky and is easy to apply (Japanese Patent Publication No.
No. 102619) has been developed. However, this hair setting composition also did not have elasticity in the formed film. Therefore, the adhesion force between hairs is sufficient,
It is desired to develop a hair setting composition that has a formed film that is highly elastic and does not become stiff, has excellent style retention, is non-greasy, is smooth, and is easy to get rid of during the process from application to dry finishing. Was there.

[0005]

Therefore, as a result of intensive studies, the present inventor has found that by combining a specific polyether compound and carrageenan, hair having excellent set-holding power and good feel is obtained. The present invention was completed by finding that a setting agent composition was obtained.

That is, according to the present invention, the number of terminal hydroxyl groups is 3 to.
20 to 100 mol (average number of moles) of propylene oxide and 0 to 20 mol (average number of moles) of ethylene oxide were addition-polymerized to the polyhydric alcohol of 6 or the polyhydric alcohol of polyglycerin having an average degree of polymerization of 3 or more. A polyether compound having a viscosity at 25 ° C of 500
~ 1500 cps polyether compound 0.5-3
A hair setting composition comprising 0.0% by weight and 0.05 to 10.0% by weight of carrageenan.

The polyether compound used in the present invention has a viscosity of 500 to 1500 cps. When the viscosity is less than 500 cps, the fixing strength of hair is insufficient, and when the viscosity exceeds 1500 cps, stickiness is felt. Examples of the polyhydric alcohol in the polyether compound include decaglycerin, pentaerythritol and the like. Of these, decaglycerin is particularly preferable. The numbers of propylene oxide (PO) and ethylene oxide (EO) can be appropriately selected on the condition that the viscosity of the PO, EO adduct of the polyhydric alcohol is 500 to 1500 cps.

Preferred polyether compounds are represented by the following general formula (1), and among these, particularly preferred compounds are x + y = 70 and z = 10. This compound is commercially available as Bertamol DG-25 (trade name of NOF CORPORATION).

[0009]

[Chemical 2]

(Where x + y = 20 to 100 and z = 7 to
The number of 15 is shown. ) The polyether compound is 0.5 to 30.0 in the total composition.
%, Preferably 3.0 to 20.0% by weight. If it is less than 0.5% by weight, the effect as a setting agent cannot be obtained, and if it exceeds 30.0% by weight, a large amount is added to the hair, which causes a problem in washing hair and is not preferable.

The carrageenan used in the invention is
Any of kappa, iota and lambda carrageenan may be used, and iota or lambda carrageenan is particularly preferable. These may be used alone or in combination of two or more, and are added in an amount of 0.05 to 10.0% by weight, preferably 0.2 to 5.0% by weight, based on the total composition. 0.05% by weight
If the amount is less than 10%, the effect as a setting agent cannot be obtained, and if it exceeds 10.0% by weight, a large amount is applied to the hair, which causes a problem in washing hair and is not preferable.

The blending ratio of the polyether compound and carrageenan is as follows: polyether compound: carrageenan = 0.
It is preferably 5: 1 to 20: 1, and 1: 1 to 10 :.
1 is more preferred.

In the present invention, it is preferable to further blend an ethylene oxide addition type nonionic surfactant as the surfactant. Examples of the ethylene oxide addition type nonionic surfactant include polyoxyethylene hydrogenated castor oil (25 to 100 EO) and polyoxyethylene lauryl ether (10 to 25 EO). Of these, polyoxyethylene hydrogenated castor oil is particularly preferable. The blending amount is 0.1 to 3.0% by weight
Is preferred. By blending an ethylene oxide addition type nonionic surfactant among the surfactants, there is an advantage that stickiness is small.
