摘要:
Provided is a cosmetic including silicone microparticles, in which the silicone microparticles include 100 parts by mass of silicone elastomer spherical microparticles having a volume average particle diameter within a range from 0.1 to 100 μm, and 0.5 to 25 parts by mass of a polyorganosilsesquioxane that coats the surface of the silicone elastomer spherical microparticles, and the silicone elastomer is capable of absorbing not less than 200 parts by mass of a polymethylsiloxane having a viscosity at 25° C. of not more than 10 mm2/s per 100 parts by mass of the silicone elastomer. Even if containing a silicone oil, the cosmetic exhibits favorable feelings upon use, with no spreading difficulties, stickiness, greasiness, or oily film feeling or the like.

The present invention provide a paste organopolysiloxane elastomer composition comprises at least: (I) specific organopolysiloxane elastomer microparticle and (II) an oil that is a liquid at 25° C.; wherein the organopolysiloxane elastomer microparticle of the component (I) is a spherical or an amorphous microparticle having a volume-average particle diameter of 2 to 50 μm and can absorb 200 or more parts by mass of a methyl polysiloxane having a dynamic viscosity of 10 mm2/second or less at 25° C. relative to 100 parts by mass of the organopolysiloxane elastomer microparticle. There can be a paste organopolysiloxane elastomer composition having excellent stability in storage, blending, and so on with a cosmetic and so on while giving a sleek and light feeling without a heavy spreading property and without such feelings as an oily, a sticky, and an oil-film feeling.
摘要:
Silicone composite particles are provided in which silicone elastomer spherical particles having a volume average particle size of 0.1-100 μm are coated with an organosilsesquioxane-based silicone resin containing inorganic nano-particles having a volume average particle size of up to 100 nm. The silicone composite particles are compounded in a cosmetic composition to exert a UV screening effect or bactericidal property inherent to inorganic nano-particles and to impart a pleasant feel on use. A preparing method and a cosmetic composition are also provided.

摘要:
High quality bisphenol A is produced from a neutral crystalline adduct of bisphenol A and phenol by fusing the adduct in an atmosphere having a maximum oxygen content of 0.005 % by volume, followed by evaporation of liberated phenol. The crystalline adduct may be mixed with an aliphatic carboxylic acid before the fusion to reduce the coloring of the product. When an acidic crystalline adduct is used, the use of a strong alkali salt of an aliphatic carboxylic acid is suitably used. Interior surfaces of the apparatuses for carrying out the fusion and evaporation are desirably washed with an organic solvent to remove oxygen therefrom. The evaporation of phenol is suitably performed by two stage steam stripping wherein a used stripping gas obtained in the second stage is employed as a stripping gas in the first stage while steam is used as the stripping gas in the second stage.
