Description

The present invention relates to cosmetics.

A skin lotion is a transparent liquid cosmetic that has the function of imparting moisture and moisturizing ingredients to the skin when applied to the skin. Here, since the lotion is mainly composed of water, there are few components that can be contained in the lotion, and it is difficult to distinguish it from other cosmetics.
Due to the above circumstances, lotions with unique physical properties or functions have been researched and developed in the field of lotion development in recent years in order to distinguish them from other cosmetics.

As a conventional technique, it is known that a water-soluble polymer such as locust bean gum is used to adjust the viscosity of cosmetics (Patent Document 1).
It is also known that a combination of xanthan gum and locust bean gum can provide a gel-like substance having high strength and transparency with a small amount (Patent Document 2).

Further, in Patent Document 3, by dispersing a specific porous powder and a fluorine compound-treated powder in water in which a water-soluble polymer is dissolved or swollen using a dispersant and/or a water-soluble solvent, It is disclosed that it is a cosmetic that has excellent stability over time, spreads easily, has a refreshing feeling of use and a refreshing finish, and has good makeup sustainability.

In addition, an oil-in-water cosmetic containing a water-soluble polymer and a powder whose surface is treated with a compound having a perfluoropolyether group having a molecular weight of 300 or more has good dispersibility and adhesion to the skin. It is known to have excellent properties such as a good emollient feeling, a high emollient feeling, and improved makeup durability (Patent Document 4).

By the way, Patent Document 5 discloses that a glycerin-containing gel cosmetic containing a polyoxyalkylene polyhydric alcohol ether improves slip during application.

In the process of researching and developing a lotion with unique physical properties or functions that other lotions do not have, we discovered that although lotions containing locust bean gum have a plump appearance, the locust bean gum-derived slimy texture makes them suitable as lotions. There was a problem with the feeling of use.

An object of the present invention, which has been made in view of the above circumstances, is to provide a cosmetic that contains locust bean gum, thereby maintaining a plump appearance and suppressing sliminess derived from locust bean gum. Another object of the present invention is to provide a skin lotion having unique physical properties or functions not found in other skin lotions.

The present inventors have found that by adding a substance having a specific structure to a cosmetic containing locust bean gum, the slimy texture derived from locust bean gum is maintained while maintaining the plump appearance peculiar to the cosmetic containing locust bean gum. We found that it can be suppressed, and completed the present invention. In addition, by adding a substance having a specific structure to a cosmetic containing locust bean gum to a cosmetic having a water content above a certain level, the cosmetic has a plump appearance when placed on the hand and is used. The shape is collapsed by the application operation of (1), and the cosmetic has a water-like property and has a unique crumbling feeling that it fits into the skin, and has completed the present invention.

That is, the present invention for solving the above problems is a cosmetic containing locust bean gum, and further comprising a polyoxyalkylene polyhydric alcohol ether.
Effect of the Invention According to the present invention, it is possible to provide a cosmetic containing locust bean gum, in which locust bean gum-derived sliminess is suppressed while maintaining a plump appearance.

Here, in the present specification, the term “plump appearance” refers to an overall rounded appearance with the vicinity of the center of the cosmetic as the apex of swelling. Specifically, for example, "plump appearance" means that 0.3 mL of cosmetic material is allowed to stand on BIOSKIN (manufactured by Beaulux) using a dropper, and left to stand at room temperature at 20°C for 1 hour. It means that the cosmetic has a diameter of 12 mm or less after the passage of time.

In the present specification, the term “Nurutsuki” means that when a cosmetic is applied to the skin, as the cosmetic is spread thinly, a thin film that feels slippery between the skin and the hand is interposed. It means a nice feeling (see Japanese Patent Application Laid-Open No. 2012-47667).

In a preferred embodiment of the present invention, the cosmetic has a moisture content of 70% by mass or more.
Since the cosmetic contains a polyoxyalkylene polyhydric alcohol ether and the water content of the cosmetic is 70% by mass or more, the cosmetic has a plump appearance when placed on the hand and can be shaped by the application operation during use. is disintegrated, it becomes a water-like property, and a lotion having a unique collapsing feeling that it fits into the skin can be provided.

In addition, the lotions (cosmetics) of Examples 1 to 5 containing glycereth-12 (polyoxyalkylene polyhydric alcohol ether) have a water content of 70% by mass or more, so that the lotions (cosmetics) When put on the hand, it has a plump appearance, and the shape collapses due to the application operation during use, and it becomes a water-like property and has a unique crumbling feeling that it fits into the skin.

Among them, the lotions (cosmetics) of Examples 1 and 3 to 5 containing 0.05% by mass or more of glycereth-12 (polyoxyalkylene polyhydric alcohol ether) contain glycereth-12 (polyoxyalkylene polyhydric alcohol ether). Compared to the lotion (cosmetics) of Example 2 containing 0.005% by mass of 0.005% by mass of locust bean gum, the slimy texture derived from locust bean gum was maintained while maintaining the shape retention due to the inclusion of locust bean gum. was suppressed.

Here, in the lotions (cosmetics) of Examples 1 and 3 to 5, the content ratio of locust bean gum and glycereth-12 (polyoxyalkylene polyhydric alcohol ether) was 5:1 to It is in the range of 1:10.
That is, the blending ratio of the content of locust bean gum and glycereth-12 (polyoxyalkylene polyhydric alcohol ether) is in the range of 5:1 to 1:10, so that the locust bean gum is included, It was found that sliminess derived from locust bean gum could be sufficiently suppressed while maintaining a plump appearance.

In addition, the lotions (cosmetics) of Examples 1 to 5, in which the content of concentrated glycerin and diglycerin (glycerin) is 5% by mass or more, maintain a warm feeling due to the inclusion of glycerin. , The stickiness derived from glycerin was suppressed.

It was found to reduce the stickiness of

That is, from the results of Table 2, as the polyoxyalkylene polyhydric alcohol ether in Test Example 1, when glycerin is used in which polyoxyalkylene having 5 to 30 repeating oxyalkylene units having 2 carbon atoms is added to glycerin. Also, it was found that the same effect as in Test Example 1 was obtained.

In addition, from the results in Table 2, it is recognized that when polyoxyalkylene is added to glycerin, sliminess derived from locust bean gum and stickiness derived from glycerin can be suppressed regardless of the chain length of polyoxyalkylene.
That is, as the polyoxyalkylene polyhydric alcohol ether in Test Example 1, even in the case of using glycerin added with polyoxyalkylene having 5 to 30 repeating oxyalkylene units having 2 to 4 carbon atoms added to glycerin, Test Example 1 It was found that the same effect as that of 1 was obtained. It was also found that if the compound contained in the cosmetic is a compound in which a polyoxyalkylene is added to a polyhydric alcohol via an ether bond, the same effect as in Test Example 1 can be expected.

Moreover, from the results in Table 2, it was found that the polyoxyalkylene polyhydric alcohol ether can be used as a sliminess improving agent for cosmetics containing locust bean gum.
