Abstract:
A composition comprising a fragrance releasing siloxane having the formula:M.sub.f M.sup.F.sub.g D.sub.h D.sup.F.sub.i T.sub.j T.sup.F.sub.k Q.sub.lwhere M has the formula R.sup.7 R.sup.8 R.sup.9 SiO.sub.1/2 ; M.sup.F has the formula R.sup.7 R.sup.8 R.sup.F SiO.sub.1/2 ; D has the formula R.sup.10 R.sup.11 SiO.sub.2/2 ; D.sup.F has the formula R.sup.10 R.sup.F SiO.sub.2/2 ; T has the formula R.sup.12 SiO.sub.3/2 ; T.sup.F has the formula R.sup.F SiO.sub.3/2 ; and Q has the formula SiO.sub.4/2 where R.sup.7, R.sup.8, R.sup.9, R.sup.10, R.sup.11 and R.sup.12 are each independently selected for each M, M.sup.F, D, D.sup.F, T and T.sup.F from the group of one to forty carbon atom monovalent alkyl or alkoxy radicals and six to forty carbon atom monovalent aryl or aryloxy radicals where the subscripts f or g are positive, and one or more of the subscripts h, i, j, k or l are positive, subject to the limitation that one of the subscripts g, i, or k is one or greater than one; where R.sup.F has the formula (R.sup.1).sub.a (R.sup.2).sub.b (R.sup.3).sub.c (R.sup.4).sub.d (R.sup.5).sub.e SiR.sup.U with R.sup.U a two to forty atom divalent hydrocarbon radical, where R.sup.1, R.sup.2 and R.sup.3 are derived from the group of fragrant esters, ketones, or aldehydes, each independently having the structure:R.sup.7 --CH.dbd.C(O--)--R.sup.8,with R.sup.4 and R.sup.5 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; R.sup.7 is selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms and R.sup.8 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.
