MULTI-COMPARTMENT MATERIAL FOR THE THERMALLY STIMULATED DELIVERY OF SUBSTANCES OF INTEREST, PREPARATION METHOD THEREOF AND USES OF SAME

摘要

The invention relates to a material in the form of solid particles having a diameter varying between 1 µm and 1 cm and formed by a continuous shell comprising at least one silicon oxide, said shell enclosing an aqueous phase. The material is characterised in that the aforementioned aqueous phase contains at least one hydrophilic substance of interest SH and at least one droplet of a fatty phase mainly comprising a crystallisable oil in the solid state at the storage temperature of the material, said crystallisable oil having a melting temperature (TF) below 100°C and containing at least one lipophilic substance of interest SL. The invention also relates to a method for preparing said material, to the use thereof for the thermally stimulated delivery of active substances, as well as to compositions containing same.
