Description

Water-in-oil type cosmetic
Technical Field
The present invention relates to water-in-oil cosmetics. More specifically, the present invention relates to a water-in-oil type cosmetic which realizes excellent hiding power, moist feeling in use, and ease of application at the time of application.
Background
In cosmetics such as foundations, oily cosmetics are preferably used if the hiding power is important, but most of them give a greasy and sticky feel to the user. In order to improve such a feeling of use, studies have been made on powder-containing oil-in-water cosmetics blended with a powder, but there is room for improvement from the viewpoint of hiding power. On the other hand, water-in-oil cosmetics having high hiding power have been studied, but there is room for improvement from the viewpoints of a moist feel at the time of use, a moist feel, or ease of extension during use.
In addition, in water-in-oil cosmetics, the emulsion state may change due to vibration during transportation or the like, but cosmetics having little change and high stability are also demanded.

Detailed Description
[ First cosmetic product ]
The first water-in-oil cosmetic of the present invention (hereinafter, may be simply referred to as a first cosmetic) comprises: (A) a hydrophilic polymer compound having a sol-gel conversion ability, (B) xyloglucan, (C) water, and (D) an oil component. The components contained in the cosmetic of the present invention are described below.
[ Hydrophilic Polymer Compound having Sol gel conversion ability ]
The first cosmetic product of the present invention is a composition comprising a specific hydrophilic polymer compound. One of them is a hydrophilic polymer compound having a sol-gel conversion ability (hereinafter, sometimes referred to as component (a)).
The hydrophilic polymer compound having a sol-gel conversion ability is a compound which reversibly forms a hydrophilic gel when a stimulus such as a temperature change is applied to the aqueous solution (sol). Such compounds are widely used in cosmetics, pharmaceuticals, and the like, and various compounds are known. As hydrophilic polymers having sol-gel conversion ability, agar, carrageenan, gellan gum, and the like are known, for example. Agar, carrageenan and gellan gum are preferably used as component (a) because they are dissolved by heating and then solidified by cooling to form a gel, which is not easily affected by ions, and because they can be easily produced and solidified uniformly. Furthermore, the present invention can be preferably applied to the cosmetic of the present invention in terms of the properties, stability, feel in use, and the like of the gel.
(A) The component (a) is solidified by cooling, but the gelation point (solidification point) of the aqueous solution is preferably 30 ℃ or higher from the viewpoint of solidification at room temperature, and is preferably 50 ℃ or lower, and preferably 45 ℃ or lower from the viewpoint of solubility at the time of production. In view of these, the gelation point of the aqueous solution of component (A) is preferably 30 to 50℃and more preferably 30 to 45 ℃. (A) The gelation point of the aqueous solution of the component (A) was determined by collecting about 10ml of the aqueous solution of the gel in a medium-sized test tube (diameter: 1.5 cm. Times.16 cm) and inserting the test tube into a thermometer, and sometimes cooling the test tube obliquely.
Agar has a basic structure containing a large amount of galactose as monosaccharide units. Further, the agar pectin contains neutral agarose and an agar pectin having an ionic group, and a sulfuric acid group is contained in a part of the agar pectin.
Carrageenan is also a basic structure with a large content of galactose as monosaccharide units. Carrageenan is classified into three types of kappa-carrageenan, lambda-carrageenan and iota-carrageenan, but any of them may be used.
Gellan gum is a linear heteropolysaccharide having a main chain containing a repeating unit formed by combining 4 saccharides, i.e., 2 glucose, 1 glucuronic acid, and 1 rhamnose. In addition, the hydroxyl group of glucose contained in the repeating unit may be substituted with an acetyl group.
Among them, agar is commercially available in many forms, and can be selected according to the purpose. As the agar, for example, commercially available products such as etanercept agar PS-84, Z-10, AX-30, AX-100, AX-200, T-1, S-5, M-7, CS-110 (manufactured by etanercept food industry Co., ltd.) and the like can be used.
In the first cosmetic of the present invention, the content of the component (a) is preferably 0.01 to 7% by mass, more preferably 0.03 to 5% by mass, based on the total mass of the cosmetic.
[ Xyloglucan ]
The first cosmetic of the present invention contains xyloglucan (hereinafter, sometimes referred to as component (B)) as a hydrophilic polymer compound in combination with the above component (a). The basic structure of xyloglucan is a structure which takes beta-1, 4-glucan as a main chain and takes xylose side chains as alpha-1, 6 bonding on the main chain. Galactose and fucose may be bonded as side chains.
As a representative example of xyloglucan, acid bean seed gum derived from tamarind seeds can be mentioned. In the present invention, the sour bean paste is preferably used. The sour bean gum is xyloglucan derived from natural products, but has little impurity, and can obtain stable products when the sour bean gum is used. The sour bean seed gum is prepared by pulverizing, separating, and refining tamarind seed.
In the first cosmetic of the present invention, the content of the component (B) is preferably 0.01 to 7% by mass, more preferably 0.03 to 5% by mass, based on the total mass of the cosmetic.
In the first cosmetic of the present invention, the effect is changed depending on the blending ratio of the component (a) and the component (B). In order to strongly exhibit the effect of the present invention, the ratio of the content of the component (a) to the content of the component (B) is preferably 50:1 to 1:50, more preferably 20:1 to 1:20.
