DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a spray-type hairdressing composition which provides a mist-like hairdressing agent. More specifically, the present invention relates to a spray-type hair styling agent which has a high setting force and a good feeling of the hair after setting and does not cause stiffness 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 hair styling agent not using a propellant.

[0002]

2. Description of the Related Art Heretofore, hair sprays for hair (hereinafter referred to as spray-type hair styling agents) which discharge hair styling agents in a mist form have been widely used. In particular, in recent years, there has been a tendency to prefer a spray-type hair styling agent having excellent setting power, and the amount of the hair fixing polymer compound (setting agent) has been increasing. However, in the case of a hair styling agent containing a large amount of a setting agent as described above, after drying, the hair has a strong stiffness, and the touch of the hair is impaired, or flaking such that white powdery particles adhere to the hair. May occur.

[0003] Conventionally, in order to solve the drawbacks of such a hairdressing agent, for example, a hair cosmetic which gives a good feeling to the hair after setting with a combination of an anionic polymer and a specific polyether-modified silicone (JP-A-Hei. 6-10041
No. 8) or a hair cosmetic in which the feeling of hair after setting is improved by a combination of a hair fixing polymer, a branched fatty acid ester and a cationic surfactant (Japanese Patent Publication No. 6-96).
504) has been proposed.

[0004]

However, such a hair styling agent has not yet sufficiently solved the above-mentioned problems. SUMMARY OF THE INVENTION An object of the present invention is to provide a spray-type hair styling agent having a strong setting force, a smooth film formed on the hair, no stiffness of the hair, and no flaking.

The present inventor has conducted various studies to solve the drawbacks of the conventional hair spray. As a result, a specific silicone derivative was used for the polymer compound for fixing hair, and furthermore, a monodisperse of fatty acid and polyglycerin was used. By combining an ester compound, it has been found that a spray-type hair styling agent having a high setting power, a good feel to the hair after setting, and free from stiffness and flaking can be obtained, and has completed the present invention.

That is, the present invention provides (a) a polymer compound for fixing hair, and (b) a compound represented by the following formula (I):

Embedded image (Wherein, R ¹ is an alkyl group having 1 to 22 carbon atoms, R ² is an alkoxyl group or a hydroxyl group, x is 1 to 3, p is 1 to 3, q
Represents 5 to 30, m represents 1 to 100, and n represents 1 to 200), and (c) a spray-type hairdressing composition comprising a monoester compound of a fatty acid and polyglycerin; Another object of the present invention is to provide an aerosol-type spray-type hair styling agent further comprising (d) a propellant.

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

The compounding amount of such a high molecular compound is 1 to 7% by weight, particularly preferably 1.5 to 6% by weight, based on the total amount of the composition. If the amount 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. When an amphoteric or anionic hair fixing polymer compound is used, a part or all of its functional groups may be replaced with an organic compound such as 2-amino-2-methyl-1-propanol or triethanolamine, if necessary.

The amount of the above-mentioned monoester compound is 0.03 to 0.5% by weight based on the total weight of the composition.
-0.3% by weight is particularly preferred. 0.03% by weight
When the amount is less than the above range, a feeling of stiffness occurs and a good feel to the hair cannot be obtained. On the other hand, when the amount is more than 0.5% by weight, a sticky feeling becomes strong or a high setting force cannot be obtained.

The cosmetic of the present invention preferably contains a pyroglutamic acid ester-based nonionic surfactant in order to obtain a resin film having good transparency and washability. Examples of such a pyroglutamic acid ester-based nonionic surfactant include an ester of a polyoxyalkylene-added polyhydric alcohol and pyroglutamic acid, and a diester of a polyoxyalkylene-added polyhydric alcohol and pyroglutamic acid and a fatty acid.

It is preferable that one or more of these pyroglutamic acid ester nonionic surfactants are added in an amount of 0.001 to 0.5% by weight based on the total amount of the composition. If the compounding amount is less than 0.001% by weight, a good resin film cannot be obtained, and liquor tends to be formed at a low temperature.
If it exceeds 0.5% by weight, the feeling of use of the hairdressing composition is impaired.

The spray-type hairdressing composition of the present invention is prepared by mixing and dissolving each component in a solvent such as ethanol or an ethanol / water mixture by a conventional method, and filling the mixture in a spray container.
