Organic silicone fine particles, method for producing organic silicone fine particles, cosmetics containing organic silicone fine particles, resin composition, and coating composition
High demands in actual use scenes in recent years, for example, in resin compositions, further improvement in optical properties such as total light transmittance and haze, further improvement in heat-resistant coloring, usability in cosmetics (use It can fully respond to further improvements in time elongation and spread), further improvement in feeling of use (stickiness, unevenness, sustainability), and further improvement in matteness and tactile sensation in coating compositions. Provided are organic silicone fine particles, a method for producing the organic silicone fine particles, a cosmetic, a resin composition and a coating composition containing the organic silicone fine particles. As a whole, the surface corresponding to each surface of the tetrahedron has a shape in which a concave portion (11) having a substantially circular opening is formed. Organosilicone fine particles in a range (however, the average value is an average value of 20 arbitrary particles extracted from a scanning electron micrograph image of the organosilicone fine particles).近年における実際の使用場面での高度の要求、例えば樹脂組成物においては全光線透過率やヘイズ等の光学特性の更なる向上、また耐熱着色性の更なる向上、化粧料においては使用性（使用時の伸びや広がり）の更なる向上、また使用感（べとつき、凹凸感、持続性）の更なる向上、そして塗料組成物においては艶消し性や触感の更なる向上に充分に応えることができる有機シリコーン微粒子、該有機シリコーン微粒子の製造方法、該有機シリコーン微粒子を含有する化粧料、樹脂組成物及び塗料組成物を提供する。全体として四面体の各面に相当する面に開口部が概ね円形の凹部（１１）が形成された形状を呈し、微粒子個々の外形の最大径（Ｌ）の平均値が０．５～２０μｍの範囲（但し、平均値は有機シリコーン微粒子の走査型電子顕微鏡写真像から抽出した任意の２０個についての平均値）にある有機シリコーン微粒子とした。
