Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a foamy hair cosmetic, and more particularly to a foamy hair cosmetic that has excellent storage stability and produces fine-textured and stable foam.

[Prior art]

In recent years, foam-like products have been widely used as hair cosmetics and skin cosmetics. Foamy aerosol compositions used in such products include those based on cationic and anionic polymers (Japanese Unexamined Patent Publication No. 197206/1986);
Those using polyoxyethylene-oleyl ether (
JP-A-48-38286), those using polyoxyethylene-sorbitan fatty acid ester and sorbitan fatty acid ester are known.

However, all of these foamy aerosol compositions have the disadvantage that the foam produced lacks stability and is easily crushed, making it difficult to obtain a good feeling and effect when using it.

Another problem with polyphenols is that they are extremely unstable and easily change due to heat or oxygen.

In order to solve this problem, a method using a porphyrin-copper complex and an organic reducing agent in combination (Japanese Patent Application Laid-open No. 63-145213
), but such compositions can be heated at 45°C, for example.
When stored at such high temperatures for a long period of time, the pH changes and turbidity or precipitation occurs in the composition, making it difficult to obtain good use effects.

[Problem to be solved by the invention]

The present invention was made in view of the above circumstances, and it is an object of the present invention to provide a foamy hair cosmetic that has excellent storage stability and is capable of forming fine-textured and stable foam.

[Means to solve the problem]

As a result of intensive research to achieve the above object, the present inventors discovered that at least one substance selected from propyl gallate, ascorbic acids, and plant extracts, a cationic polymer, and a nonionic surfactant. The present inventors have discovered that a hair cosmetic as an essential ingredient is effective for the above purpose, and have completed the present invention.

That is, the foam hair cosmetic of the present invention contains propyl gallate,
It is characterized by containing at least one substance selected from ascorbic acids and plant extracts, a cationic polymer, and a nonionic surfactant as essential components.

The first essential component of the present invention is a substance selected from propyl gallate, ascorbic acids, and plant extracts.

The amount of propyl gallate to be blended is preferably 0.05 to 0.5% by weight based on the total amount of the foam hair cosmetic of the present invention. If it is less than 0.05% by weight, hair dyeing properties tend to be poor, and if it exceeds 0.5% by weight, stability tends to be poor.

Further, ascorbic acids include shi-ascorbic acid, L-dehydroascorbic acid, or salts thereof. Examples of salts include metal salts of ascorbic acid such as magnesium ascorbyl phosphate and magnesium ascorbate sulfate; metal salts of ascorbic acid such as sodium L-ascorbate, potassium L-ascorbate, and calcium L-ascorbate; Examples include metal salts of L-dehydroascorbic acid such as sodium L-dehydroascorbate, potassium dehydroascorbate, and calcium L-dehydroascorbate. Particularly preferred is L-ascorbic acid or L-ascorbic acid.
- Sodium ascorbate. The amount of ascorbic acid compounded is 0.0000000000000000000000000 with respect to the total amount of the foamy hair cosmetic of the present invention.
Preferably it is 5 to 5% by weight.

If it is less than 0.5% by weight, hair dyeing properties tend to be poor, and if it exceeds 5% by weight, stability tends to be poor.

In addition, as plant extracts, Acacia japonica and Jiyu.

Japanese sagebrush, hamamelis, japanese horsetail, logwood, horse chestnut, amacha, hypericum, western ivy, rosemary, althea, cinchona, hawthorn, kingin, coltsfoot, horsetail, hop, pine, horsetail, chamomile, nettle, peony, Japanese juniper, Examples include peach and mixed plant extracts.

Particularly preferred are Aspergillus japonica, Jasmine japonica, Porphyra japonica, Hamamelis, Chimney japonica, Boshonsi or logwood. The amount of the plant extract to be blended is 0.0% in terms of the amount of evaporation residue of the extract based on the total amount of the foam hair cosmetic of the present invention.
Preferably, it is between 0.05 and 2% by weight. If it is less than 0.05% by weight, the hair dyeing properties tend to be poor, and if it is less than 2% by weight.
If it exceeds , stability tends to deteriorate.

Examples of the cationic polymer which is the second essential component of the present invention include ether of hydroxycellulose and glycidyltrimethylammonium chloride (trade name: Leogard G [manufactured by Lion Corporation], Polymer JR-30M-12
5 and the same 400 [manufactured by Union Carbide]), quaternized vinylpyrrolidone-dimethylaminoethyl methacrylic acid copolymer (trade name: GAFQUAT734 and 7)
55 [manufactured by GAF]), dimethyldiallylammonium chloride polymer (product name: MERQUATloo (manufactured by Merck & Co.)), dimethyldiallylammonium chloride acrylamide copolymer (product name: MERQUAT)
Among these compounds, the ether of hydroxycellulose and glycidyltrimethylammonium chloride is particularly preferred.

The content of the cationic polymer is preferably 0.05 to 3% by weight based on the total amount of the foam hair cosmetic of the present invention. If it is less than 0.05% by weight, the texture and stability of the foam tends to deteriorate, and if it exceeds 3% by weight, it tends to become less sticky.

In addition, as the nonionic surfactant which is the third essential component of the present invention, for example, polyoxyethylene (hereinafter referred to as POE
POE alkyl ethers such as oleyl ether, POE stearyl ether, POE nonylphenyl ether, POE octylphenyl ether, etc.
Alkylphenyl ether, POE (20 [meaning the number of moles of oxyethylene added is 20, the same applies hereinafter]) sorbitan monolaurate, POE sorbitan fatty acid ester such as POE (20) sorbitan monooleate, coconut oil fatty acid jetanolamide, There are fatty acid alkylolamides such as lauric acid monoethanolamide and stearic acid jetanolamide. Particularly preferred is carbon number 8-18.
is a fatty acid alkylolamide.

The amount of nonionic surfactant to be blended is preferably 0.1 to 3% by weight based on the total amount of the foam hair cosmetic of the present invention in the case of a non-rinsable formulation. If the amount is less than 0.1% by weight, the texture and stability of the foam will deteriorate, and if it exceeds 3% by weight, the foam will be difficult to disappear and will become sticky, which is not desirable. In addition, in the case of a wash-off formulation, 0.1 to 20
Preferably, it is % by weight. If it is less than 0.1% by weight, the texture and stability of the foam will deteriorate, and if it exceeds 20% by weight, no improvement in the effect will be observed.

In addition, the pH of the foamy hair cosmetic is preferably 2 to 6, particularly 3.
~5 is preferred. If the pH is less than 2, the hair dyeing effect will be poor, and if the pH is more than 6, the hair dyeing effect and stability will be poor, which is not desirable.

The foamy hair cosmetic composition of the present invention contains the above-mentioned components as essential components, but optional components such as those listed below may be added as necessary to the extent that the effects of the present invention are not impaired.

Such optional ingredients include polyvinylpyrrolidone,

(1) Fill a storage-stable hair cosmetic into a transparent aerosol glass bottle at 45°C.
It was stored in a constant temperature bath for one month, and its appearance and pH were evaluated to evaluate its stability. The evaluation criteria were as follows.

O: No change in appearance or pH 0: Slight change in appearance or pH Δ: Appearance or pH change of 0.5 or more ×: Appearance of precipitation or pH change of 1 or more (2) Foam Stability A sample stock solution filled in a sealed container with the propellant shown in Table 1 was injected into a wide-mouthed cylindrical glass container to generate a certain amount of foam, and the foam was subjected to a sensory test by 20 panelists. and its stability was evaluated. Stability rating is 1
The resistance to breakage when crushed by hand was evaluated based on the following criteria.

O: Stable and not easy to break 0: Slightly easy to break Δ: Slightly easy to break ×: Easy to break The quality of the foam when viewed was evaluated using the following criteria.

O: Foam is fine and creamy 0: Foam is slightly coarse Δ: Foam is slightly coarse The foamy hair cosmetic of the present invention containing both a cationic polymer and a nonionic surfactant has good storage stability and produces fine-textured and stable foam, but it lacks either of these.
