The present invention concerns a dynamic mixture obtained by combining, in the presence of water, at least one diamine derivative, comprising at least one heteroaryl moiety, with at least two perfuming aldehydes and/or ketones. The invention's mixture is capable of releasing in a controlled and prolonged manner said perfuming compounds, in particular perfuming ingredients, into the surrounding environment. The invention's dynamic mixture gives rise to a more evenly distributed positive effect for the release of the different carbonyl compounds which are part of the mixture than other examples reported in the prior art.

aqueous solutions. Kinetic rate constants and equilibrium constants for the formation and hydrolysis of aminals were determined. The performance of dynamic mixtures as delivery systems for perfumery ingredients was tested after deposition onto cotton, and the long-lastingness of fragrance evaporation was investigated by dynamic headspace analysis against a reference sample. The simplicity of the concept
