Abstract

Abstract Delivery systems generated by reversible hydrazone formation from hydrazine derivatives (see Fig. 1) and carbonyl compounds in H 2 O efficiently increase the long- lastingness of volatile aldehydes and ketones (R 1 R 2 C [DOUBLE BOND] O) in various perfumery applications. The hydrazones are usually obtained in an (E) configuration at the imine double bond (NHN [DOUBLE BOND] C) and, in the case of aliphatic ...
