摘要:
This invention is a cosmetic material containing a pasty composition obtained by adding at least one acidic substance selected from a group comprising organic acids, phosphoric acid and phosphates to a mixture comprising a crosslinking type organopolysiloxane polymer having a polyoxyalkylene group and a liquid oil, adding a basic neutralizing agent to adjust the pH to 5-8, and removing volatile components by heating and/or decompression . This pasty composition is a composition wherein the propionaldehyde amount produced by adding an identical amount of water to the composition and heating at 60 DEG C for 24 hours is 100 ppm or less.

PROBLEM TO BE SOLVED: To provide a method of producing addition product of a compound containing SiH group onto a reactant having one double bond in an aqueous media. SOLUTION: The invention relates to the method of producing organically modified siloxanes and silanes by noble-metal-catalyzed reaction of siloxanes and/or silanes having at least one SiH group with a compound having one double bond, wherein the reaction is carried out in the presence of water as a reaction medium. The organically modified siloxanes and/or silanes obtained by the reaction are useful for a compound for detergent, an additive for dispersing in producing paint, foam stabilizer for polyurethane foam, textile treating agents, etc. COPYRIGHT: (C)2007,JPO&INPIT
