cosmetic odor-modified silicone compound, containing the same, and method of purification of the modified silicone compound having a branched polymer comprising a hydrophilic group

摘要

For reaction solution by addition reaction in the rhodium catalyst or in the presence of platinum, and alkenyl sugar organohydrogenpolysiloxane, alkenyl polyoxyalkylene, alkenyl and glycerol and / or given below: or (A) ( it is subjected to a purification treatment of B), (meq / g) is 0.002 or less degree of unsaturation, aldehyde emissions of 0.5 hours heat aging time at 70ppm or less in 0.23 N hydrochloric acid during 50 ℃ some, cosmetics containing this compound and odorless-modified silicone compound. Hydrogenated to (A) the remaining unsaturated bond, subsequent decomposition of the aldehyde condensation product with an acid substance-containing aqueous solution of pH7 below. Decomposition of the propenyl ether compound with an acid material-containing aqueous solution (B) pH7 or less, and subsequent hydrogenation of the residual unsaturated bonds to the aldehyde produced.
