(57) [Summary] (Modifications) [PROBLEMS] A chemically modified polymeric siloxane that releases fragrance during hydrolysis and has a slow release rate of fragrance molecules so as to exhibit fragrance for a long time. SOLUTION: The formula (R 1 O) a (R 2 O) b (R 3 O) c (R 4 ) d (R 5 ) e A fragrance releasing siloxane comprising a substituent of SiR U. In the formula, R U is a divalent hydrocarbon group having 2 to 40 atoms, R 1 O, R 2 O and R 3 O are each independently an alcohol R 1 O A fragrant alkoxide moiety derived from H, R 2 OH and R 3 OH, wherein R 1 OH, R 2 OH and R 3 OH are independently fragrant alcohols, and R 4 and R 5 are carbon atoms; Selected from the group consisting of a monovalent hydrocarbon group of 1 to 40 and a monovalent alkoxy group of 1 to 40 carbon atoms; 3, the symbols b, c, d and e are a + b + It has a value in the range of 0 to 2 provided that c + d + e = 3. |
