Claim:
An active ingredient-releasing cyclic siloxane selected from the group of siloxanes having the formulas: where R 10 , R 11 , R 12 , and R 13 are each independently selected from the group of monovalent C 1 -C 24 hydrocarbon radicals, the subscripts n and q are each independently greater than or equal to 1, the subscripts p, r, and s are each independently equal to or greater than 0 with the proviso that n+p must be equal to or greater than 3 and that q+r+s must be equal to or greater than 3; where R F has the formula (R 1 O) a (R 2 O) b (R 3 O) c (R 4 ) d (R 5 ) e SiR U with R U a C 2 -C 40 divalent hydrocarbon radical and R 4 and R 5 independently selected from the group consisting of monovalent hydrocarbon radicals having from one to forty carbon atoms, 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, where each R 1 O, R 2 O and R 3 O are independently selected from the group of conjugate bases consisting of conjugate bases derived from the group of alcohol active ingredients consisting of R 1 OH, R 2 OH, and R 3 OH where R 1 , R 2 and R 3 are independently monovalent hydrocarbon radicals having from four to one hundred carbon atoms and the group of conjugate bases derived from the group of carbonyl active ingredients having the structure: R 7 —C(R 8 )═C(O—)—R 9 where R 7 , R 8 , and R 9 are each independently selected from the group consisting of hydrogen and monovalent hydrocarbon radicals having from one to one hundred carbon atoms.
