Summary of the Invention

Problems to be Solved by the Invention

[0004] However, conventional cosmetics have had a problem of poor viscosity stability when stored for a long time. In particular, in the case of cosmetics having a relatively high viscosity, for example, when pressure is applied to the cosmetics using a filling machine to fill the cosmetics into a container, there has been a problem that the viscosity of the cosmetics is difficult to recover to the viscosity before the pressure is applied. Also, in terms of elongation during application, adhesion to the skin, and covering power of the finish, they have not been sufficiently satisfactory.

Means for Solving the Problems

[0005] The inventors have discovered that by using a small amount of sorbitan fatty acid ester together with cation-modified clay minerals, phenyl-modified silicone, and polyether-modified silicone, it is possible to obtain a water-in-oil emulsion composition that exhibits good viscosity stability, good spreadability during application, good adhesion to the skin, and excellent coverage in the finished product, as the viscosity is easily restored even when pressure is applied to the cosmetic and viscosity decreases.

[0006] The present invention comprises the following components (A), (B), (C), and (D): (A) Cationic modified clay minerals substituted with quaternary ammonium ions, (B) Phenyl-modified silicone in liquid form at 25°C, (C) Sorbitan fatty acid ester 0.00005~0.3% by mass, (D) Polyether-modified silicone This relates to a water-in-oil emulsion composition containing the following: [Effects of the Invention]

[0007] The water-in-oil emulsion composition of the present invention exhibits excellent viscosity stability even after long-term storage. In this invention, "excellent viscosity stability even after long-term storage" means that even if the viscosity of the water-in-oil emulsion composition decreases due to pressure applied by a filling machine or the like, it easily recovers to the viscosity it had before the pressure was applied. Furthermore, it excels in its spreadability during application, its adherence to the skin, and its coverage. [Modes for carrying out the invention]

[0008] The cationic modified clay mineral of component (A) used in the present invention is one that has been substituted with quaternary ammonium ions and can be used without limitation as long as it is commonly used in cosmetics. For example, cationic modified clay minerals obtained by substituting layered clay minerals such as bentonite, laponite, hectorite, montmorillonite, and aluminum magnesium silicate with a quaternary ammonium salt type cationic surfactant are preferred. Here, the quaternary ammonium salt type cationic surfactant is given by the following formula (1):

[Examples]

[0068] Examples 1-12 and Comparative Examples 1-2 Water-in-oil emulsion cosmetics (foundations) with the composition shown in Table 1 were manufactured, and their viscosity was measured immediately after manufacturing and after one month of storage. The viscosity stability under pressure from a filling machine, spreadability during application, adherence to the skin, and coverage were also evaluated. The results are shown in Table 1. Note that, because Comparative Examples 1 and 2 had low viscosity, the viscosity stability when pressure was applied by the filling machine was not evaluated.

[0069] (Manufacturing method) A water-in-oil emulsion cosmetic was obtained by adding and mixing aqueous phase components to an oil phase containing components (A), (B), (C), (D), (E), (F), and (G).

[0070] (Evaluation method) (1) Viscosity measurement: For each water-in-oil emulsion cosmetic, the viscosity was measured immediately after manufacturing and after storage at 30°C for one month. This was done using a helical viscometer (TVB-10 model, manufactured by Toki Sangyo Co., Ltd.), rotor HTC, rotation speed 10, and measurement time 60 seconds at 30°C. Note that these viscosities were measured without applying pressure from the filling machine described in (2) below. The viscosity values ​​are listed in the following items in Table 1. (A): Viscosity immediately after opening (30℃) / mPa·s (i): Viscosity after 1 month (30℃) / mPa·s

[0071] (2) Viscosity stability when pressure is applied by a filling machine: For each water-in-oil emulsion cosmetic, pressure was applied using a filling machine under the following conditions. 40 g of each water-in-oil emulsion cosmetic was placed in a 50 mL sample bottle, and the viscosity (c) after storage at 30°C for one month was measured in the same manner as in (1) above. From these viscosities, the viscosity stability (viscosity recovery) when pressure is applied by a filling machine was determined using the following formula. A value closer to 100% indicates a smaller viscosity change and is therefore superior. Viscosity stability (viscosity recovery) (%) when pressure is applied by a filling machine = (((U): Viscosity after 1 month following pressure application) / ((I): Viscosity after 1 month)) × 100 • Pressure conditions for the filling machine: Arahata Food Machine Co., Ltd., electric piston-type filling machine SBK-1-9L, Φ40 cylinder, nozzle inner diameter Φ5mm, filling time: 0.3 (sec)

[0072] (3) Spread when applied: Three expert evaluators applied 0.03g of each water-in-oil emulsion cosmetic to a 2x3cm area of ​​skin on the inside of their forearms using their fingers. 2 The product was applied to a sample of the specified size, and its ease of application was evaluated on a 5-point scale as follows. The results are shown as the total score from the three participants. 5; It stretches very well. 4; It stretches well. 3; It stretches fairly well. 2; It doesn't stretch very well. 1; It doesn't stretch well.

[0073] (4) Feel on the skin: Three expert evaluators applied 0.03g of each water-in-oil emulsion cosmetic to a 2x3cm area of ​​skin on the inside of their forearms using their fingers. 2 The product was applied to the skin in an amount the size of a small sample, and massaged for 20 seconds at a speed of one back-and-forth motion per second. The adherence of the cosmetic to the skin was evaluated on the following 5-point scale. The results are shown as the total score of the three participants. Furthermore, the feeling of adhesion to the skin refers to the sensation that, after massaging for 20 seconds, your fingers feel as if they are being sucked in and stop in place, indicating that the water-in-oil emulsion cosmetic has adhered closely to the skin. 5; There is a noticeable feeling of adhesion. 4; It feels sticky. 3; It feels slightly sticky. 2; It doesn't feel like it's sticking to anything. 1; It doesn't feel sticky.

[0074] (5) Coverage: Three expert evaluators applied 0.25g of each water-in-oil emulsion cosmetic to their faces using their fingers and evaluated its coverage of pores and uneven skin tone on a five-point scale. The results are shown as the total score from the three evaluators. 5; It clearly has good coverage. 4; It has good coverage. 3; It has moderate coverage. 2; It doesn't offer much coverage. 1.
