The present invention relates to microcapsules delivering long lasting and intense vanilla-based odor note. More particularly, the present invention concerns a microcapsule comprising between 10% and 30% by weight, relative to the total weight of the microcapsule, of a particular perfuming ingredient imparting a vanilla-based odor note, which can be used in perfuming compositions and perfuming consumer products.

The invention described herein provides methods and materials that can impart long-term stability to polyelectrolyte complex coacervate droplets and create complex coacervate emulsions. The methodology described herein is designed to use one or more of a wide variety of comb polyelectrolytes in order to produce stable water-in-water emulsions with precisely controlled droplet size and enhanced stability profiles. The stabilized water-in-water emulsions microdroplets of the invention can further encapsulate active agents such as proteins and the like in a manner that protects them from the surrounding environment, thus allowing the compositions to serve as bio-microreactors and the like.

An emulsion comprising a continuous aqueous phase and a dispersed fatty phase in the form of drops, or conversely, wherein the drops comprise a shell formed of at least one anionic polymer comprising at least one carboxylic acid function and at least one cationic polymer comprising at least two amine functional groups, wherein the quantity of amine functional groups provided by the cationic polymer in the fatty phase is between 0.2 mol and 10.5 mol per gram of fatty phase.

A renewable material for releasing a self-healing agent includes a renewable polymeric substrate with capsules and a reactant dispersed in the renewable polymeric substrate. The capsules may be formed from a first renewable shell polymer and may enclose the renewable self-healing agent. The reactant may be suitable for reacting with the renewable self-healing agent to form a polymer.
