Abstract: The present invention is concerned with an insect repellent composition and a method of using the same to repel insects over an extended period of time. The compositions of the invention include natural insect repellents and can provide a prolongation of complete protection times to a 12 hour minimum thereby enabling a once daily dosage regime if required.

Abstract: The present invention relates to a conjugate suitable for topical application to the skin of a user, the conjugate comprising at least one volatile active coupled directly or indirectly to a carrier substance, wherein the carrier substance is substantially resistant to permeation through the skin of a user under ambient conditions, and wherein the coupling between the active and the carrier substance is such that said coupling is cleaved under said ambient conditions when said conjugate has been applied to the skin of a user, so as to release said volatile active from said carrier substance in a sustained release manner. The present invention also relates to a composition including such a conjugate and also processes of preparing such conjugates and compositions.
