The composition comprising a physiologically-active agent and a composition represented by general formula (I), wherein X may represent sulfur, oxygen or nitrogen; a and b may be 0 or 1, c may be 0, 1 or 2, except that when X is oxygen, a, b and c are 0, when X is nitrogen c is 0 and only one of a or b is 1, and when X is sulfur a and b are 0; A is a branched or a straight chain, divalent aliphatic radical having from 0 to 2 double bonds; R' is selected from the group consisting of H, a lower alkyl group having from 1 to 4 carbon atoms, phenyl, lower alkyl or halogen substituted phenyl, acetamido, halogen, piperidinyl, lower alkyl or halogen substituted piperidinyl, carbalkoxy, carboxamide, and alkanoyl; and R is hydrogen or a lower alkyl group having from 1 to 4 carbon atoms, (II) or (III), wherein R'' is H or halogen, and salts, e.g., acid or quaternary derivatives thereof. These compositions are useful in topical or transdermal applications of the physiologically-active agent. Other subject compositions relate to an improved method of dyeing fibers, improved delivery of plant nutrients, improved plant pest control, improved delivery of plant growth regulators, improved acid-catalyzed conversion of a reactant into a reaction product and an improved insect repellant. |
