    摘要： PURPOSE
    To provide a hydrosilylation reaction process, and the like for (AB)n-type polyether-modified silicone compositions having sufficient quality and foam conditioning properties even when a low-cost glycol ether compound is used as a raw material.
    SOLUTION
    A method of manufacturing a composition containing a polyether-polysiloxane block copolymer (A'), including step 1 of mixing raw material components including at least (a1) double terminated alkenyl polyether, and (N + S) a specific monovalent sodium carboxylate solution, step 2 of removing a solvent component (S) from the system, and a step of subjecting the raw material components to a hydrosilylation reaction (provided that the sum of component (a1), component (a2), and component (B'): = 100:40 to 80, and the amount of Na+ in component (N) with regard to Component (B') is added is within a range of 3.8 to 43 wt. ppm), as well as a foam-enhancing composition, and use thereof.

    摘要： [Problem] To provide a polyether-modified silicone composition that can be supplied in large quantities at low cost, that is very safe and environmentally friendly, and that has excellent quality in terms of mixing stability, handling and workability, and storage stability in compositions containing a dispersion medium, and that can be used in applications such as surfactants and foam stabilizers, to provide applications for this polyether-modified silicone composition, and to provide a manufacturing method for this polyether-modified silicone composition. [Solution] Provided is a polyether-modified silicone composition comprising (A) a polyether-modified silicone, and (B) a monool organic compound selected from (B1) a glycol ether compound having a hydrogen atom substituted by an alkyl group having from 2 to 8 carbon atoms at one end, a secondary alcoholic hydroxy group at the other end, from 2 to 3 repeating oxyalkylene units having from 2 to 4 carbon atoms, and (B2) a tripropylene glycol monomethyl ether, wherein isopropyl alcohol does not exceed 1 mass% of the entire composition; applications for this composition; and a manufacturing method for this composition.

    摘要： The present invention relates to an oil-in-water cleansing cosmetic composition, containing: (A) carboxylic acid-modified silicone that is liquid at 50°C; (B) 3 to 80 mass% of an oil agent relative to the total mass of the cosmetic composition; (C) water; and (D) a basic compound; where an amount of an ionic surfactant other than the carboxylic acid-modified silicone (A) that is liquid at 50°C is 10 mass% or less relative to the total mass of the cosmetic composition. The cleansing cosmetic composition according to the present invention quickly blends with makeup grime, has a high makeup removing effect, and has excellent stability.
