Controlled release of volatile aldehydes and ketones by reversible hydrazone formation--classical" profragrances are getting dynamic.
Dynamic mixtures obtained by reversible covalent acylhydrazone formation of fragrance aldehydes and/or ketones and a hydrazide in water were found to be efficient delivery systems for the controlled release of highly volatile organic molecules.
