Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foam-shaped hair styling composition, and more specifically, it ejects into a foam at the time of ejection, and then the foam disappears promptly to transform into a gel. Also provides an excellent foam hair styling composition.

[0002]

2. Description of the Related Art Conventionally, various forms of hair styling products have been developed for the purpose of imparting conditioning to hair and imparting style retention. Among them, foam-shaped products called styling mousses and gel-shaped products called styling gels are becoming mainstream because they can easily give hair styling.

[0003]

However, each of these conventional products has advantages and disadvantages, and they are not always sufficiently satisfactory. That is, for example, in the case of a foam-shaped hair styling product, it has the advantages of being easy to handle and easy to adapt to the hair as a whole, but on the other hand, it has the drawbacks that it is difficult to use the finger style and the setting force is weak overall.

On the other hand, a gel-like hair styling product has the advantages of easy finger style and excellent setting power, but on the other hand it has poor elongation and is easily stuck to the part, making it difficult to adapt to the entire hair and hand. It has the disadvantage of being sticky.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair styling product which has good usability and also has setting properties (setting power and styling properties).

Means for Solving the Problems As a result of intensive studies to solve the above-mentioned problems, the present inventor prepared a hairdressing base having a specific composition and prepared it as an aerosol together with a propellant. It was found that the foam-like material is easily formed on the hair when it is discharged, and then the gel-like material quickly transitions to a gel-like shape with disappearance of the foam, resulting in excellent settability, thus completing the present invention.

That is, the present invention is composed of a stock solution and a propellant, and when it is made into an aerosol, it exhibits a foam-like shape at the time of discharge, and the foam disappears by rubbing the foam after the discharge and becomes a gel. A gelling, foam-like hair styling composition comprising 0.3 to 1% by weight of a polyoxyethylene linear aliphatic ether nonionic surfactant having an HLB value of 13 or more based on Griffin based on the whole stock solution, carboxyvinyl Polymer 0.1-3% by weight, ethyl alcohol 10-2
It contains 0% by weight and water, and the viscosity of the stock solution is 5000.
The present invention relates to a post-gelling foam-like hairdressing composition, which is adjusted to -60,000 cp.

The present invention also relates to a foam hair styling composition comprising the foam hair styling composition containing 0.1 to 10% by weight of a polymer film forming agent.

The present invention further relates to a foam-shaped hair styling composition containing 0.1 to 1% by weight of an amphoteric surfactant or a cosurfactant selected from polyoxyalkylene-modified organopolysiloxane in the foam-shaped hair styling composition. It relates to a composition.

Similarly, in the present invention, in the foam-shaped hair styling composition, the weight ratio of the stock solution to the propellant is 96: 4-9.
It relates to a foam hair styling composition in the range of 0:10.

The present invention will be described in detail below. Of the present invention
The post-gelling foam-like hair styling composition comprises a stock solution and a propellant, and the stock solution contains at least a specific nonionic surfactant, a carboxyvinyl polymer, ethyl alcohol and water in specific ratios. .

First, as the specific nonionic surfactant applied to the present invention, a polyoxyethylene linear aliphatic ether compound having an HLB value of 13 or more by Griffin is selected, and preferably 0.3 to 1% by weight. Is 0.4 to 0.8
It is compounded in the range of weight%. Specifically, polyoxyethylene (10) cetyl ether (HLB value 13.5),
Polyoxyethylene (25) lauryl ether (HLB
Value 16.5), polyoxyethylene (20) cetyl ether (HLB value 17.0), polyoxyethylene (5
0) oleyl ether (HLB value 18.0), polyoxyethylene (20) stearyl ether (HLB value 1
8.0), polyoxyethylene (40) cetyl ether (HLB value 20.0) and the like.

Here, when the HLB value is less than 13, polyoxyethylene (30) hexyl decyl ether (HL
In the case of branched ether type such as B value 18.0) and polyoxyethylene (10) nonyl phenyl ether (HL
In the case of an alkylphenyl ether type such as a B value of 16.5), a good foam is not formed and it is difficult to apply to the present invention.

On the other hand, if the content is less than 0.3% by weight, a good foam cannot be formed. On the other hand, if it exceeds 1% by weight, the foam disappears poorly and the transition from foam to gel does not proceed smoothly. After all it is not preferable.

Next, in the present invention, as a thickener, Hibiswako 103, Hibiswako 104, Hibiswako 105 (above, Wako Pure Chemical Industries, Ltd.), Carbopol 93
4, Carbo pole 940, Carbo pole 941 (above,
0.1 to 3% by weight, preferably 0.3 to 1% by weight, of carboxyvinyl polymer such as Goodrich Chemical Co.
It is mixed in the range of.

When the amount is less than 0.1% by weight, the gel formation after the disappearance of bubbles is insufficient, and when the amount is more than 3% by weight, the gel after the disappearance of bubbles is stiff and the elongation is deteriorated. In order to add a carboxyvinyl polymer and increase the viscosity in the system, a method of neutralizing with an organic amine such as triethanolamine according to a conventional method is adopted.

Further, in the present invention, the amount of ethyl alcohol is 10
It is important to blend in the range of ˜20% by weight. Ethyl alcohol is used to adjust the state of the foam at the time of discharge and to quickly eliminate the foam at the time of gel transfer. If it is less than 10% by weight, the foam is hard and the foam does not disappear easily, and conversely 20 weight. If it is more than%, good foam itself cannot be obtained.

In the present invention, a stock solution is prepared by adding the remaining water to the above-mentioned nonionic surfactant, carboxyvinyl polymer and ethyl alcohol, and the stock solution prepared at this time has a viscosity in the range of 5,000 to 60,000 cp. It is essential to be adjusted to. This viscosity adjustment is performed by adjusting the kind and amount of the carboxyvinyl polymer, its neutralization degree, the amount of water, and the like.

When the viscosity is lower than 5000 cp, a good gel cannot be obtained at the time of transition from the foam form, and a hair styling product having excellent setting properties cannot be obtained. On the contrary, when the viscosity is higher than 60,000 cp, the gel is hard and the elongation is deteriorated. The harmful effect of appears.

Next, in the present invention, in addition to the above-mentioned essential components, a polymer film forming agent which has been generally used conventionally in hair styling compositions is usually used for the purpose of further improving the hair styling power. It can be blended in the range of 1 to 10% by weight. Specifically, polyvinylpyrrolidone, copolymer of vinylpyrrolidone and vinyl acetate, methoxyethyl acrylate / hydroxyethyl acrylate copolymer, N-methacryloylethyl-N, N-dimethylammonium, acrylic resin alkanolamine, α- Examples thereof include N-methylcarboxybetaine / butyl methacrylate copolymer.

Further, in the present invention, an auxiliary surfactant may be added to improve the foam quality at the time of ejection. Such auxiliary surfactants include amphoteric surface active agents represented by coconut oil fatty acid amide propyldimethylaminoacetic acid betaine, coconut oil fatty acid diethanolamide, 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolinium betaine and the like. Agents, polyoxyalkylene-modified organopolysiloxane represented by dimethyl siloxane-methyl (polyoxyethylene) siloxane copolymer,
Considering the smooth transition from foam to gel, it is preferably blended in the range of 0.1 to 1% by weight.

Next, in the foam-shaped hair styling composition of the present invention, the weight ratio of the undiluted solution obtained as described above to the propellant is 96: 4 to 90:10, preferably 94: 6 to 9.
It is preferably 2: 8. If the mixing ratio of the stock solution exceeds the above upper limit, a good foam can no longer be formed, and if it is less than the above lower limit, a good gel cannot be obtained when bubbles disappear. As the propellant component, for example, liquefied petroleum gas such as LPG and liquefied gas such as dimethyl ether are preferable. Further, a compressed gas such as nitrogen gas or carbon dioxide gas may be used together.

In the present invention, in addition to the above-mentioned essential components, various components conventionally used in hairdressing preparations can be added within a range that does not impair the object of the present invention. Such components include higher alcohols, ester oils, animal and vegetable oils, oils such as silicone oils, hyaluronic acid, mucopolysaccharides such as chondroitin sulfate, amino acids, elastin hydrolysates, collagen hydrolysates, keratin hydrolysates and the like. Examples include polyhydric alcohols such as protein hydrolysates, glycerin, and 1,3-butylene glycol, other UV absorbers, chelating agents, preservatives, antioxidants, medicinal ingredients such as various vitamins, pigments, and fragrances. it can.
