Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to foam aerosol cosmetics. More specifically, there is an appropriate setting power,
TECHNICAL FIELD The present invention relates to a foamable aerosol cosmetic composition capable of restyling.

[0002]

2. Description of the Related Art Conventional so-called "super hard" type aerosol foam cosmetics have high "setting power". However, once applied to hair and then dried and solidified, "re-hairdressing" is difficult.

Further, the so-called "wax" type aerosol foam cosmetics do not solidify even after being applied to the hair, so that the "rehair styling power" is excellent. However, there is almost no "setting power".

On the other hand, in aerosol foam cosmetics,
In order to improve the feel of bubbles and the ease with which hair fits in,
Various studies have been conducted. For example, propellant LPG
By adding an appropriate amount of DME (dimethyl ether) to (liquefied petroleum gas), the foam quality can be controlled in a creamy direction, and a technique has been developed to obtain a foam that fits well to the hair and has a pleasant feel.

However, the conventional techniques have a limit in controlling the foam quality. For example, when adding DME to LPG, increasing the amount of DME added results in about 30%.
As a result, defoaming is accelerated and usability as a foamy cosmetic composition is significantly reduced.

[0006]

DISCLOSURE OF THE INVENTION The present invention is a new type of foam-type aerosol cosmetic composition that is easy to re-hairstyle and has an appropriate setting force.

[0007] Further, a foamy cosmetic having a creamy and "rich" foam quality and good foaminess is obtained, and when used as a hair cosmetic for setting, it does not harden excessively,
In addition, it is a technology that can provide hair that is easy to re-dress.

[0008]

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below.

The polyacrylic acid salt used in the present invention is a water-soluble polymer, and commercially available products such as sodium polyacrylate can be used. By blending the polyacrylic acid salt, the hair is not completely hardened even after hair styling with the cosmetic of the present invention, and re-hairstyling becomes possible. So-called "super-hard" type foam aerosol cosmetics, in contrast to the fact that after hair styling, most of the water evaporates and hardens, making it impossible to re-hairstyle. Further, by blending a polyacrylic acid salt, in the foam aerosol cosmetics, the surface of the foam is strengthened and is less likely to break, and the foaming speed is also slowed down, so when foamed when applied to the hair and spread, You can also get the effect of adapting to the entire hair. Furthermore, the foam feels moist and the feeling of use becomes excellent.

The blending amount of the polyacrylic acid salt is preferably 0.01 to 0.3% (mass percentage) based on the total amount of the stock solution. If the amount is less than 0.01%, the effect of the present invention may not be exerted on ease of redeposition. On the other hand, if it exceeds 0.3%, the setting force may be lowered, and foaming of the foamy cosmetic may be suppressed. The foam properties are influenced by the gas ratio of the propellant. Usually, in the case of foam aerosol cosmetics,
The undiluted solution / propellant gas is about 90/10, and when the gas ratio exceeds 0.1%, the setting force and the foam quality tend to be poor, and the preferable compounding amount is 0.025 to 0.0
75%. The compounding amount of polyacrylic salt is 0.1 to 0.
In the case of 3%, in order to obtain good foam quality, it is necessary to raise the gas ratio to the range of undiluted liquid / propellant gas = 85/15 to 80/20.

[0031]

EXAMPLES The present invention will be described more specifically below with reference to Examples and Comparative Examples. The invention is not limited by these examples. The blending amount is a mass percentage (%) unless otherwise specified.

Foamed aerosol cosmetics were produced by a conventional method with the formulation shown in each table, and the following evaluations were carried out.

"Re-stretching power" 0.4 g on 2 g of hair strands
A sample of g was applied, dried at room temperature for 30 minutes, and combed for ease of combing.

"Moderate setting force" 0.4 g of the sample is applied to 2 g of hair strands, and the curls are wound on a curler to form curls. After drying, this curl is compressed and the integrated value of the stress applied at that time is measured. The curl compressive stress was calculated by calculating the ratio with the integrated value of the stress when the same strand was wound with water and the same measurement was performed. The larger this value is, the stronger the setting force is, and about 3 to 15 is considered to have the setting force.
A suitable setting force is preferably 4-12.

"Foam Quality" (Ease of Familiarity with Hair) Bubbles were spread on the palm and on the hair strands (hair bundles) and evaluated organoleptically. Bubbles that are "crispy" like ordinary mousse cosmetics (registered trademark) foam at once, so it takes time to fit in the palm and strands, but it is slightly sticky like the present invention and has a "feeling chewy". There is a bubble that foams slowly, so it is easy to adapt to the palm and strands. Also,
The specific gravity of the foam was measured as a quantitative index. When the foam specific gravity immediately after ejection is 0.02 or more, the above-mentioned "feeling of stickiness" is felt. However, if it exceeds 0.1, foaming becomes extremely bad. Therefore, approximately 0.02 to 0.1 is a proper bubble specific gravity.

The criteria of sensory evaluation described in each table are as follows. Very good: ○ Normal to good: △ There is a problem: ×

[0037]

[Table 1] * 1: The foam is firm but not creamy. * 2: Less likely to form bubbles. The bubbles collapse. * 3: Cannot be measured

[0038]

[Table 2] * 1: The foam is firm but not creamy. * 2: Less likely to form bubbles. The bubbles collapse.

[0039]

[Table 3] * 1: The foam is firm but not creamy. * 2: Less likely to form bubbles. The bubbles collapse.

"Table 1" is an examination of preferable blending amounts of sodium polyacrylate. When the effect of the present invention was investigated by adding sodium polyacrylate to the general liquid formulation of a foamy cosmetic, the effect of the present invention on hair restorative strength was found to be about 0.01%, and 0.25% Approximately 0.75% had a good foam quality, and the familiarity with hair was improved.
In addition, in the formulation of "Table 1", when the content exceeds 0.1%, foaming of the foam is strongly suppressed, foaming is unlikely to occur, and the proper setting force tends to be poor.

"Table 2" is a table in which the preferable filling amount of the propellant (gas amount) is examined. In the case of general foam cosmetics, the mass ratio (stock solution / propellant) is 90/1.
Around 0 is common. Since it has an important relationship with the foam quality which is one of the effects of the present invention, it affects the foam quality (stock solution / gas).
The ratio was examined. First, the effect of the present invention was examined by using a stock solution containing a small amount of sodium polyacrylate and changing the ratio of the stock solution and the propellant. The stock solution / propellant filling mass ratio was the best in the range of 95/5 to 90/10.
On the other hand, as the amount of the propellant increases, the foaming power of the gas becomes stronger, so that it becomes difficult to confirm the foam quality, which is the characteristic effect of the present invention.

Contrary to "Table 2", "Table 3" is a table in which the effect of the present invention was investigated by using a stock solution containing a large amount of sodium polyacrylate and changing the ratio of the stock solution and the propellant. .
In this case, the stock solution / propellant filling mass ratio is 85/15 to 8
It was good in the range of 0/20, but when the filling amount of the propellant was small, no bubbles were formed. Bubbles are hard to come out especially at low temperature (5 ° C).

The following are other examples of the present invention.
All of them have an appropriate hair styling property, are easy to be re-hairstyled, and have extremely good foam quality, and are excellent in usability.
