Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a spray type hair styling composition which provides a hair styling agent in the form of mist. More specifically, the present invention relates to a spray-type hair styling agent which has a high setting force, has a good feel to the hair after setting, and does not cause stiffening or flaking. The spray type hair styling agent of the present invention is used as an aerosol type hair styling agent combined with a propellant or a mist type spray styling agent which does not use a propellant.

[0002]

2. Description of the Related Art Hair sprays for hair (hereinafter referred to as spray-type hair styling agents) which eject hair styling agents in a mist form have been widely used. In particular, in recent years, there has been a tendency for spray-type hair styling agents having excellent setting power to be preferred, and the blending amount of the polymer compound for hair fixation (setting agent) is increasing. However, such a hair styling agent containing a large amount of a set agent causes a stiff feeling in the hair after drying, impairs the feel of the hair, or causes flaking such as white powdery particles adhering to the hair. May occur.

Conventionally, in order to eliminate the drawbacks of such hair styling agents, for example, a combination of an anionic polymer and a specific polyether-modified silicone imparts a good feel to the hair after setting. 6-10041

OBJECT AND SUMMARY OF THE INVENTION However, such a hair styling agent has not yet sufficiently solved the above problems. An object of the present invention is to provide a spray-type hair styling agent which has a strong setting force, has a smooth film formed on the hair, does not cause the hair to be stiff, and does not cause flaking.

These hair-fixing polymer compounds may be used alone or in combination of two or more kinds. Particularly, acidic acrylic polymer compounds and amphoteric acrylic polymer compounds are preferable because they exhibit strong setting power.

The amount of such a polymer compound as a solid content is 1 to 7% by weight, preferably 1.5 to 6% by weight, based on the total amount of the composition. If the content of these components is less than 1% by weight, sufficient setting force cannot be obtained, while if it exceeds 7% by weight, problems such as stiffness and flaking occur. In the case of using an amphoteric or anionic hair-fixing polymer compound, some or all of its functional groups may be organic such as 2-amino-2-methyl-1-propanol and triethanolamine, if necessary.

If the blending amount is less than 0.03% by weight, flaking occurs and the smoothness of the resin film cannot be obtained. On the other hand, if the blending amount exceeds 0.5% by weight, a sticky feeling becomes strong and a high setting force cannot be obtained.

(C) Monoester of fatty acid and polyglycerin The monoester compound of fatty acid and polyglycerin used in the spray-type hair styling agent of the present invention is a fatty acid such as myristic acid, stearic acid, isostearic acid and oleic acid. , A monoester compound with polyglycerin having an average degree of polymerization of glycerin of 2 to 10. Among such monoester compounds, preferred examples include polyglyceryl monoisostearate and polyglyceryl monomyristate, and specifically NIKKOL Decaglyn
1-S, NIKKOL Hexaglyn 1-O (above, Nikko Chemicals), Sunfact 2G MIS, Sunfact 2G
MO Sunfact 2 GMS-90 (above, Koei Kogyo Co., Ltd.), Cosmol 41 (Nissin Oil Co., Ltd.), Montex M
It is commercially available under the trade name of S-6 (produced by Yuka Sangyo Co., Ltd.).

The compounding amount of the above-mentioned monoester compound is 0.03 to 0.5% by weight based on the total amount of the composition, and is 0.1.
Especially preferred is 0.3% by weight. Compounding amount is 0.03% by weight
If the amount is less than 50%, a feeling of stiffness is generated and a good feel to the hair cannot be obtained. On the other hand, if the amount is more than 0.5% by weight, the feeling of stickiness becomes strong and high setting force cannot be obtained.

The cosmetic of the present invention preferably contains a pyroglutamate nonionic surfactant in order to obtain a resin film having good transparency and washability. Examples of such pyroglutamic acid ester-based nonionic surfactants include esters of polyoxyalkylene-added polyhydric alcohols and pyroglutamic acid, or polyoxyalkylene-added polyhydric alcohols and pyroglutamic acid, and diesters of fatty acids.

Ethylene glycol, diglycerin and the like can be used, and examples of the fatty acid component include isostearic acid, myristic acid, lauric acid and oleic acid.

Of these, polyoxyethylene-added hydrogenated castor oil pyroglutamic acid isostearic acid diester (Pyrotel CPI, manufactured by Japan Emulsion), polyoxyethylene-added glyceryl pyroglutamic acid isostearic acid diester (Pyrotel GPI, manufactured by Japan Emulsion) and the like are preferable.

These pyroglutamic acid ester-based nonionic surfactants are preferably added in one kind or two or more kinds in an amount of 0.001 to 0.5% by weight based on the total amount of the composition. If the blending amount is less than 0.001% by weight, a good resin film cannot be obtained, and also, the seizure easily occurs at a low temperature.
When it exceeds 0.5% by weight, the feeling of use of the hair styling agent is impaired.

The spray-type hair styling composition of the present invention is prepared by mixing the components in a solvent such as ethanol or a mixture of ethanol / water by a conventional method to prepare a mixed solution, which is filled in a spray container. The spray-type hair styling agent of the present invention is usually filled in a spray container together with a propellant. As the propellant, propane, butane, pentane, liquefied gas such as dimethyl ether, nitrogen, compressed gas such as compressed air, and the like, any known propellant in the field of aerosol may be used, even if they are used in combination. Good. Further, the hair styling agent may be atomized by various conventionally known methods such as forming a mist form without using a propellant. Of these, aerosols using a propellant are particularly preferable.

The spray-type hair styling composition of the present invention may further contain known components such as surfactants, preservatives, fragrances, oil components, bactericides, and other known ingredients, and pigments, etc., as long as the effects of the invention are not impaired. can do.
