[Prior art and problems to be solved by the invention] Conventionally,
BACKGROUND ART Cosmetics for hair fixation, such as setting lotions, hair sprays, and foamed hair styling products, containing hair fixation polymer compounds as ingredients for maintaining hair curls and waves are known. These hair fixing cosmetics are prepared by dissolving a hair fixing polymer compound in a solvent such as a lower alcohol, typically ethanol, and storing this solution as it is in a pump dispenser container, or using a suitable liquefied gas as a propellant. mix,
Used in aerosol form.

[0003] However, such hair fixing cosmetics are
Because a large amount of hair fixing polymer compounds are used to improve the set property and set retention property, the hair becomes stiff and stiff.
There were drawbacks such as flaking and clogging of the injection port (nozzle) of the container.

[0004] Therefore, in order to improve such drawbacks,
Attempts have been made to add cosmetic oils and fats, silicone oils, surfactants, higher alcohols, etc. to an ethanol solution of a polymer compound for hair fixation (Japanese Patent Laid-Open No. 62-226
No. 919, Special Publication No. 55-10881, No. 50-105
Publication No. 40). However, aerosol-type cosmetics that contain liquefied gas as a propellant can prevent hair from becoming stiff and flaking by adding the above ingredients, and also prevent nozzle clogging due to the physical force of the propellant. However, for non-gas type spray cosmetics that use pump dispenser containers etc. that do not contain propellants, sufficient effects cannot be obtained just by adding the above ingredients, and therefore it is necessary to eliminate the above drawbacks. was difficult.

[0005] The present invention has been made in view of the above circumstances.
To provide a hair fixing cosmetic which has excellent hair styling holding power, hardly causes nozzle clogging when stored in a non-gas type spray container such as a pump dispenser container, and causes less stiffness of the hair after fixing. The purpose is to

[0006]

[Means and effects for solving the problem] As a result of intensive studies to achieve the above object, the present inventors added branched chain fatty acid ester to an ethanol solution of a hair fixing polymer compound in an amount of not more than 8% by weight of the total amount. When water is added at a certain ratio, even when the non-gas type is stored in a spray container such as a pump dispenser container without the addition of a propellant, the hair styling retention power of the hair fixing polymer compound is fully demonstrated, resulting in excellent hair styling. It has been found that a hair fixing cosmetic can be obtained that has a good holding power, has almost no clogging of the nozzle of the spray container during use, has very little stiffness on the hair after fixation, and has a good feeling of use. However, the present invention has been completed.

[0007] The present invention will be described in more detail below. The hair fixing cosmetic of the present invention is stored in a non-gas type spray container and sprayed from a nozzle during use. branched chain fatty acid ester,
It contains ethanol and water in a proportion of 8% by weight or less of the total weight.

[0008] Here, as the hair fixing polymer compound, the following can be mentioned. (1) Amphoteric compounds such as methacrylic acid ester copolymers (
2) Acidic polyvinyl ether polymer compounds such as a copolymer of methyl vinyl ether and maleic anhydride (3) Acidic acrylic polymer compounds such as an acrylic acid alkyl ester-methacrylic acid alkyl ester copolymer (4) Polyvinylpyrrolidone and the like Polyvinylpyrrolidone-based polymeric compounds such as a copolymer of vinylpyrrolidone and vinyl acetate (5) Acidic polyvinyl acetate-based polymeric compounds such as a copolymer of vinyl acetate and crotonic acid Among the above-mentioned polymeric compounds, Those having acid groups are preferably neutralized with a suitable alkaline agent such as aminomethylpropanol, aminomethylpropanediol, dimethylstearamine, sodium hydroxide, triethanolamine, potassium hydroxide, etc.

[0009] The blending amount of the above-mentioned polymer compound is preferably 0.5 to 10% (weight %, the same applies hereinafter), particularly 1 to 8%, as a pure content of the entire cosmetic. 5
If it is less than 10%, hair styling retention may decrease, and if it exceeds 10%, hair stiffness and flaking may increase.

Next, as the branched chain fatty acid ester,
Esters of branched chain fatty acids having 2 to 22 carbon atoms, particularly 3 to 18 carbon atoms, and primary alcohols having 8 to 22 carbon atoms, particularly 10 to 18 carbon atoms, are preferably used. Examples of such branched chain fatty acid esters include isopropyl myristate, isopropyl palmitate, isopropyl stearate, isopropyl oleate, isopropyl elaidate, isotridecyl myristate, isobutyl oleate, isobutyl elaidate, etc. Isotridecyl acid is preferably used.

[0011] Furthermore, the blending amount of branched chain fatty acid ester is as follows:
It is desirable that the content be 0.01 to 5%, especially 0.05 to 3% of the total cosmetics; if it is less than 0.01%, the hair may become stiff, and if it exceeds 5%, the hair may become sticky. may become severe.

Furthermore, in the present invention, ethanol is used as the solvent, but water is added to prevent nozzle clogging. The amount of water added is 8% or less of the total cosmetic composition, and 1 to 7% is particularly suitable. If it exceeds 8%, the hair styling ability will decrease, which is not preferable. Note that if the blending amount is less than 1%, the effect of preventing nozzle clogging may not be obtained.

[0013] In addition to the above-mentioned ingredients, the hair cosmetic composition of the present invention may contain other optional ingredients within the range that does not affect the effects of the present invention. Examples of optional ingredients include preservatives, ultraviolet absorbers, antioxidants, colorants, fragrances, cationic surfactants, nonionic surfactants, esters other than the above-mentioned branched chain fatty acid esters, hydrocarbons, silicone derivatives, and sterilizers. Examples include drugs, vitamins, proteins, amino acids, and herbal medicines.

[0014] The hair fixing cosmetic composition of the present invention is used by storing a solution of the above ingredients dissolved in a solvent as it is in a non-gas type spray container such as a pump dispenser container without adding a propellant.

[0015]
