DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a water-in-oil emulsion composition (hereinafter referred to as W / O emulsion) useful as a cosmetic product, a pharmaceutical product, and a household product. Specifically, it can be widely used as an external phase oil, from polar oils to non-polar oils,
Further, the present invention relates to a W / O type emulsion characterized in that the temperature stability and usability of the obtained emulsion composition are extremely excellent.

[Prior art] Conventionally, to obtain a W / O emulsion, HLB is used as an emulsifier.
A lipophilic surfactant having a value of 1 to 12, for example, a polyhydric alcohol fatty acid ester based activator such as glycerin fatty acid ester or sorbitan fatty acid ester is used, and the activator is added to the oil phase.
About 0.4 to 5.0 g was added and dissolved by heating at about 70 to 80 ° C., then an aqueous phase heated to about the same temperature was added and stirred with a homomixer to obtain a W / O type emulsion.

[Problems to be Solved by the Invention] However, the W / O emulsion thus obtained is a system excellent in temperature stability and usability as compared with an oil-in-water emulsion (hereinafter referred to as O / W emulsion). However, there was a drawback that it was difficult to obtain. For example, regarding the temperature stability, at low temperatures, the oil phase, which is a continuous phase, is likely to be separated by aggregation of water droplets, and at high temperatures, the particle size increases due to coalescence of water droplets, and the particles settle to the lower layer, and the upper layer becomes oily. A phenomenon such as oil phase separation, which is a phase only, occurred. On the other hand, in terms of usability, since the outer phase is oily, it has advantages such as protection of skin and imparting of flexibility in the field of cosmetics and pharmaceuticals, but on the other hand, there is a problem that stickiness during use and skin sensitization are high. It was

As one method of improving the temperature stability, there is a method of increasing the viscosity by blending a large amount of wax in the oil phase,
This improves low-temperature stability, but in high-temperature storage, the oil phase separation due to coalescence of water droplets cannot be sufficiently improved due to the softening and melting of the blended wax, which causes a new problem regarding usability such as spreadability. There was a drawback that it would occur.

Needless to say, the problem of operability and usability is solved,
Furthermore, it was found that the high molecular weight silicone contained in the oil phase gives a good spread of the obtained emulsion, and when applied to the skin, for example, gives a refreshing and smooth feeling, and the present invention is based on this finding. It came to completion.

[Effects of the Invention] The W / O emulsion of the present invention comprises an organically modified clay mineral produced from a water-swellable clay mineral, a quaternary ammonium salt type cationic surfactant and a polyoxyalkylene modified organopolysiloxane in the formulation. By using it as an emulsifying agent or gelling agent, its compounding amount may be as small as 0.25 to 7%, and by controlling the compounding amount or the ratio of the inner aqueous phase or the outer oil phase, a solidifying agent such as wax can be formed. Viscosity can be adjusted without blending a large amount, oils with high polarity that were difficult to blend in the past can be used, and excellent stability over a wide temperature range Is. When a high molecular weight silicone is used as the oil phase component of the W / O type emulsion, the obtained emulsion has excellent spreadability and a function of improving usability such as giving a refreshing and smooth feel when applied to the skin.
