PROBLEM TO BE SOLVED: To provide a water-in-oil type emulsion composition which uses organic-modified clay mineral and does not use cyclic silicone oil, and to provide a cosmetic, further in detail, to provide a stable water-in-oil type emulsion composition which is formed by blending a silicone oil other than a cyclic silicone oil and a hydrocarbon oil or an ester oil with each other with a mass ratio of 100/0-20/80, and to provide a cosmetic, and to provide a water-in-oil type emulsifier composition which can be used for producing the water-in-oil type emulsion composition and for the cosmetic.SOLUTION: The water-in-oil type emulsifier composition is formed by combining: a silicone compound represented by general formula (1) (described in the claim) having weight-average molecular weight of 500-200,000 and with a branched silicone chain a silicone compound represented by general formula (5) (described in the specification) and an organic-modified clay mineral, and the water-in-oil type emulsion composition and the cosmetic use the water-in-oil type emulsifier composition.COPYRIGHT: (C)2012,JPO&INPIT【課題】有機変性粘土鉱物を用いた油中水型乳化組成物並びに化粧料において、環状シリコーン油を使用せずに油中水型乳化組成物並びに化粧料を提供すること、更に詳しくは、環状シリコーン油を除くシリコーン油と炭化水素油やエステル油を質量比で100/0~20/8の比率で配合できる安定な油中水型乳化組成物並びに化粧料を提供することにある。また、それらの油中水型乳化組成物並びに化粧料製造に利用できる油中水型乳化剤組成物を提供することにある。【解決手段】一般式(1)で示される重量平均分子量が500~200,000のシリコーン鎖が分岐しているシリコーン化合物と、一般式(5)で示されるシリコーン化合物と、(C)有機変性粘土鉱物とを組み合わせた油中水型乳化剤組成物、及び、該乳化剤組成物を使用した油中水型化粧料並びに化粧料。【選択図】なし
