Abstract: An external composition for skin comprises 0.1% by mass to 8% by mass of a non-emulsified silicone elastomer; a polyether-modified silicone surfactant; and a hydrophilic nonionic surfactant. The hydrophilic nonionic surfactant comprises a glycerin-derived surfactant. The polyether-modified silicone surfactant is 0.3 part by mass or more with respect to 1 part by mass of the silicone elastomer. The glycerin-derived surfactant is 0.2 part by mass or more with respect to 1 part by mass of the silicone elastomer. In a case where an amphoteric surfactant is included, the amphoteric surfactant is 1.5 parts by mass or less with respect to 1 part by mass of the glycerin-derived surfactant. The viscosity of the composition is 9,500 mPa·s or less.

Abstract: A purpose of the present invention is to provide an oil-in-water emulsion composition that is stable even when using solid oils from which it was conventionally considered to be difficult to form large oil-based particles exceeding 50 μm, and also improving the uniformity of the particle sizes and the shapes of the oil-based particles. The present invention relates to an oil-in-water emulsion composition in which oil-based particles containing a solid oil, a liquid oil and a powder are dispersed in a water phase, wherein: the oil-based particles have an average particle size of 50 μm to 10 mm; and the powder is contained inside the oil-based particles.

Abstract: A composition including a lamellar gel phase contains a first nonionic surfactant having hydrophobic moieties respectively on both sides of a hydrophilic moiety. The first nonionic surfactant constitutes at least a portion of the lamellar gel phase. A content by percentage of higher aliphatic alcohols or higher fatty acids is 1% by mass or less relative to the mass of the composition.

Abstract: A solid or semi-solid water-in-oil type emulsion cosmetic has a hardness that can be balm-like, the cosmetic has an excellent moisturizing effect, exhibiting upon use a unique sensation of blending as if melting when applied to skin, and is capable of stably incorporating a water-soluble or hydrophilic drug. A water-in-oil type emulsion cosmetic contains: (A) an organically modified clay mineral; (B) a surfactant having an HLB of no more than 6; (C) a wax; (D) a silicone elastomer; (E) a volatile oil; and (F) water.
