Abstract: Provided is a copolymer having a carbosiloxane dendrimer structure, where the amount of monomers having a carbosiloxane dendrimer structure is significantly reduced. Also provided is a composition, cosmetic raw material, film-forming agent, and a cosmetic material comprising the copolymer, as well as a method of manufacturing the copolymer and the like. The copolymer is a copolymer of (a1) an unsaturated monomer having a carbosiloxane dendrimer structure having a radically polymerizable organic group, and (a2) an unsaturated monomer having a radically polymerizable vinyl group, which is different from component (a1). The amount of unreacted unsaturated monomers (a1) and saturated monomers derived from the unreacted unsaturated monomers (a1) is 2500 ppm or less relative to the copolymer.

Abstract: An anti-foaming agent containing (A) an organopolysiloxane and a finely powdered inorganic filler, (B) a polyoxyalkylene group-containing branched chain organopolysiloxane, and (C) an anionic surfactant. This anti-foaming agent exhibits stable anti-foaming performance even at high temperatures that reach, for example, 80QC or under strongly alkaline conditions and produces no aggregates.

Abstract: A silicone composition comprises: (A) a silicone based antifoam agent and (B) a carboxy functional silicone. Optionally, the silicone composition further comprises at least one of: (C) an emulsifier selected from a silicone polyether emulsifier, an organic emulsifier, or mixtures thereof, or (D) a hydroxy compound selected from a glycol, water, or mixtures thereof. A process for preparing the silicone composition comprises the step of: combining (A), (B), and optionally at least one of (C) or (D).

Abstract: A silicone foam control composition comprises a finely divided filler, an organosilicon compound that contains at least two silicon-bonded hydroxy groups in each molecule, an organosilicon compound having at least two silicon-bonded aminoxy groups in each molecule, and optionally an inert fluid. At least (B) and (C) react so the silicone foam control composition has a viscosity of from 1,000 mPa·s to 1,000,000 mPa·s at 25° C. An oil-in-water silicone emulsion composition comprising the silicone foam control composition, a process for making the silicone foam control composition, and a method of using the composition, are also disclosed.

Abstract: A water-repellent lightweight cellular concrete panel having on its surface a water-repellent treatment layer provided by a water-based emulsion of a non-film-forming amino-modified organopolysiloxane. A water-based emulsion of a non-film-forming amino-modified organopolysiloxane is applied, by a spray method or a roller coating method, on the surface of lightweight cellular concrete panel and drying is carried out. An O/W water-based emulsion of a non-film-forming amino-modified organopolysiloxane that has an amine equivalent weight of 500 to 100,000 gram/mol and a viscosity at 25° C. of 50 to 1,000,000 mPa·s.

Abstract: A surface-treating agent for imparting both water repellency or unsusceptibility to water absorption and excellent antifouling properties to a surface of a material, especially a material for outdoor use; and a material whose surface has been treated with the surface-treating agent.

Abstract: A composition is disclosed which comprises an amino radical-containing organopolysiloxane and an organopolysiloxane containing at least 3 epoxy radical-containing organic groups in each molecule.
