A fragrance releasing siloxane comprising a substituent having the formula (R1O)a(R2O)b(R3O)c(R4)d(R5)eSiRU with RU a two to forty atom divalent hydrocarbon radical where R1, R2 and R3 are derived from the group of fragrant esters, ketones, or aldehydes, each independently having the structure: R7-CH=C(O-)-R8, with R4 and R5 selected from the group consisting of monovalent hydrocarbon radical having from one to forty carbon atoms and monovalent alkoxy radicals having from one to forty carbon atoms, where the subscript a has a value ranging from 1 to 3 and the subscripts b, c, d, and e have values ranging from 0 to 2 subject to the limitation that a+b+c+d+e=3; R7 is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms and R8 is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms where the subscript a has a value ranging from 1 to 3 and the subscripts b, c, d, and e have values ranging from 0 to 2 subject to the limitation that a+b+c+d+e=3.
