Description

The present invention relates to an oil-in-water emulsified solid cosmetic.

Emulsified cosmetics are easy-to-use formulations that have been used in cosmetics because oil-soluble active ingredients such as emollient oils, ultraviolet absorbers, and oil-soluble agents can be efficiently spread on the skin. Therefore, it is often used not only in skin care cosmetics but also in make-up cosmetics. Among them, the oil-in-water emulsified cosmetic has a continuous phase composed of an aqueous component, so that when used as a cosmetic, a light and smooth spread, a refreshing feeling, and a refreshing feeling on the skin can be obtained. It has the characteristics of improving the adhesion to cosmetics and the durability of makeup.

Agar may be added to such an oil-in-water emulsified cosmetic for the purpose of imparting a feeling of freshness and refreshing feeling, or for the purpose of making it solid. On the other hand, when agar is added, the adhesion of the cosmetic to the skin and the durability of the makeup may be deteriorated. In order to solve such a problem, in Patent Document 1, polyethylene glycol is blended in an oil-in-water solid cosmetic containing agar. According to Patent Document 1, by blending polyethylene glycol, adhesion to the skin and long-lasting makeup are improved.

Japanese Patent Application Laid-Open No. 2003-95862

When agar is added to an oil-in-water type cosmetic for the purpose of ensuring shape retention in the cosmetic, the cosmetic becomes hard. Due to this, when consumers try to take makeup with their fingers or application tools, it becomes difficult for the makeup to come off (makeup does not come off easily), and it is difficult for an appropriate amount of makeup to adhere to the fingers or application tools. The phenomenon is seen. On the contrary, if the amount of agar blended is reduced in order to improve the removal of cosmetics, there arises a problem that the shape retention is not maintained after long-term storage. That is, in the oil-in-water emulsified cosmetic containing agar, there was a trade-off relationship between the shape-retaining property of maintaining the solid state and the removal of the cosmetic.

Therefore, an object of the present invention is to provide an oil-in-water emulsified solid cosmetic having good removal of cosmetics while maintaining a solid state even after long-term storage.

Another object of the present invention is to provide an oil-in-water emulsified solid cosmetic that spreads smoothly when the cosmetic is applied on the skin. Further, another object of the present invention is to provide an oil-in-water emulsified solid cosmetic having high adhesion to the skin when the cosmetic is applied and the effect of the cosmetic is sustained.

In the present invention, the following components (A) to (D);
(A) Monomer-derived structural unit (a) selected from the group consisting of (meth) acrylic acid and (meth) acrylic acid alkyl, polyoxyethylene alkyl ether itaconate and polyoxyethylene (meth) acrylic acid. A polymer comprising a monomer-derived structural unit (b) selected from the group consisting of alkyl ethers.
(B) Agar,
An oil-in-water emulsified solid cosmetic containing (C) an oil agent and (D) water.

According to the present invention, it is possible to provide an oil-in-water emulsified solid cosmetic with good removal of cosmetics while maintaining the solid state even after long-term storage. Further, according to the present invention, it is possible to provide an oil-in-water emulsified solid cosmetic that spreads smoothly when the cosmetic is applied on the skin. Further, according to the present invention, it is possible to provide an oil-in-water emulsified solid cosmetic having a high adhesion to the skin when the cosmetic is applied and the effect of the cosmetic is sustained.

Hereinafter, embodiments of the present invention will be described. The present invention is not limited to the following embodiments. In the present specification, "X to Y" indicating a range includes X and Y, and means "X or more and Y or less". Unless otherwise specified, operations and measurements of physical properties are performed under the conditions of room temperature (20 to 25 ° C.) / relative humidity of 45 to 55% RH.

The first embodiment of the present invention is a monomer-derived structural unit selected from the group consisting of the following components (A) to (D); (A) (meth) acrylic acid and (meth) alkyl (meth) acrylic acid. A polymer containing a) and a structural unit (b) derived from a monomer selected from the group consisting of polyoxyalkylene alkyl ether itaconic acid and polyoxyalkylene alkyl ether (meth) acrylic acid, (B) agar. , (C) Oil agent, and (D) Water-in-water emulsified solid cosmetic containing water.

As described above, in solid cosmetics, there is a trade-off relationship between the shape retention of the cosmetic and the so-called goodness of adhesion to the application tool, etc., and it is difficult to achieve both. .. On the other hand, by adopting the configuration of the present embodiment, the removal is improved while maintaining the solid shape. Further, the cosmetic of the present embodiment spreads smoothly when the cosmetic is applied on the skin, the cosmetic has high adhesion to the skin, and the cosmetic exerts its effect for a long period of time. (Makeup lasts long).

The detailed mechanism by which the cosmetics of the present embodiment exert the above effects is unknown, but it is considered as follows. The following mechanism does not limit the scope of the present invention at all.

Since agar has a network structure in which polymer chains are intricately entangled with each other, agar may be added to maintain the solid state of cosmetics. However, when agar is added to the cosmetic in a certain amount or more in order to give the solid cosmetic a form, the network structure of the agar becomes strong and the cosmetic becomes hard, so that the removal of the cosmetic deteriorates. On the other hand, the component (A) in the present embodiment has a polyoxyalkylene alkyl ether chain in the structure. This polyoxyalkylene alkyl ether chain interacts with the component (B), and the component (A) reduces the solidifying power of the component (B) (it becomes slightly creamy). It improves and spreads smoothly when applied on the skin. Further, by retaining the gel structure formed by the component (A) and the component (B) on the skin, the feeling of adhesion to the skin is improved, and the makeup lasts longer. On the other hand, oil droplets (emulsified droplets) formed by the component (C) are retained in the lipophilic portion (alkyl chain) of the component (A), and the gel structure composed of the components (A) and (B) moves the oil droplets. It is considered that the oil droplets are prevented from coalescing to suppress the oil droplets, the emulsification stability is improved, and the solid state is maintained even after long-term storage.

Further, since the component (A) has a polyoxyalkylene alkyl ether chain in the structure, water can be well held together with the component (B) at the polyoxyethylene alkyl ether chain portion, so that the cosmetic can be applied to the skin. When applied, it gives freshness and allows the cosmetic to spread smoothly on the skin.

The solid in the solid cosmetics in the present invention is clearly distinguished from the gel-like state, which is a semi-solid state having fluidity when laid down in a bavarois shape, and refers to a state in which it does not flow even when laid down. Specifically, the solid cosmetics are loaded with a measurement sample filled in a polypropylene jar container having a diameter of 75 mm and a height of 52 mm so as not to generate air space, covered with a lid, left in a constant temperature bath at 30 ° C. for 24 hours, and then loaded.
