Use of an aromatic ingredient of a dynamic mixture, for the controlled release of active aldehydes or ketones, obtainable by reacting, in a medium containing water, i) at least one active aldehyde or ketone having a molecular weight between 80 and 230 g / mol and which is an aromatic, flavoring, insect repellent or attractant ingredient, in particular being selected from the group consisting of C5-20 aromatic aldehydes and C5-20 aromatic ketones; with ii) at least one derivative of the formula in which: n represents an integer ranging from 0 to 3; R 1 independently represents one another, a hydrogen atom, an optionally substituted phenyl group, or an optionally substituted C1-18 alkyl or alkenyl group; R 2 represents, independently of one another, a hydrogen atom, an optionally substituted phenyl group, or an optionally substituted C 1-6 alkyl or alkenyl group; two R 2 or two R 1 or R 1 and R 2, taken together, can form a C3-5 alkanediyl or alkenodiyl group; and R 3 R 4 and each represent a C1-3 alkyl group substituted by an optionally substituted phenyl group; R 3 and R 4 or R 3 and the adjacent R 1, taken together, can form a C2-4 alkanediyl or alkenodiyl group. |
