    Abstract: An objective of the invention is to provide a powdered solid cosmetic that has excellent powder dispersibility and high impact resistance, while also having a texture similar to that in the case in which an elastic spherical powder is blended. The powdered solid cosmetic according to the present invention contains (A) a non-elastic spherical powder having a crushing strength per particle of 30 MPa or higher; (B) 1% to 15% by mass of iron oxide; (C) a gel-type partially crosslinked organopolysiloxane polymer; and (D) a non-ionic surfactant having an HLB of 10 or lower; wherein the (A) non-elastic spherical powder constitutes 90% by mass or more of all spherical powders contained in the cosmetic.

    Abstract: A W/O/W emulsion composition comprising a large amount of silicone oil and having a high viscosity and a high stability is provided.
    The W/O/W emulsion composition comprises: an inner aqueous phase; an oil phase in which the inner aqueous phase is dispersed; and an outer aqueous phase in which the oil phase is dispersed, wherein the inner aqueous phase comprises an osmotic pressure regulator that prepares the inner aqueous phase to have a higher osmotic pressure than the outer aqueous phase, the oil phase comprises a silicone oil that is 0.5 times by mass or greater of the total oil phase, and a silicone-based surfactant having a silicone skeleton as a main skeleton and a hydrophilic group in a side chain, and the outer aqueous phase comprises a polyol and an alkyl-modified carboxyvinyl polymer.

    Abstract: A transparent composition having UV protection effect is provided, wherein the UV protection effect is improved after the composition is contacted with moisture, such as water or sweat, more than that immediately after the composition is applied, while maintaining high transparency. The transparent composition contains (a) a UV absorbent, (b) an oil component having a refractive index in the range from 1.5 to 1.7, (c) an oil component having a refractive index of not less than 1.3 and less than 1.5, and (d) a powder having a refractive index in the range from 1.45 to 1.55, wherein a mixed oil component obtained by mixing the (b) oil component having a refractive index in the range from 1.5 to 1.7 and the (C) oil component having a refractive index of not less than 1.3 and less than 1.5 has a refractive index in the range from 1.44 to 1.56.
