Title (EN) CORE-SHELL MATERIAL, METHOD FOR PREPARING SAME, AND USE THEREOF FOR THE THERMOSTIMULATED GENERATION OF SUBSTANCES OF INTEREST
(FR) MATERIAU CŒUR ECORCE, SON PROCEDE DE PREPARATION ET UTILISATION POUR LA DELIVRANCE THERMOSTIMULEE DE SUBSTANCES D'INTERET
Abstract: front page image
(EN)The present invention relates to a material in the form of solid particles consisting of a continuous shell including at least one silica oxide, said shell confining at least one oil phase, said material being characterized in that said oil phase is solid at the storage temperature of said material and predominantly contains a crystallizable oil that has a melting temperature (TF) of less than 100°C and at least one substance of interest, and in that the diameter of the particles varies from 1 µm to 1 cm. The invention also relates to a method for preparing said material, to the use thereof for the thermostimulated generation of active substances, as well as to compositions containing same.
(FR)La présente invention est relative à un matériau se présentant sous forme de particules solides constituées d'une enveloppe continue comprenant au moins un oxyde de silice, ladite enveloppe emprisonnant au moins une phase grasse, ledit matériau étant caractérisé en ce que ladite phase grasse est solide à la température de stockage dudit matériau et comprend majoritairement une huile cristallisable ayant une température de fusion (TF) inférieure à 1000C et au moins une substance d'intérêt, et en ce que le diamètre des particules varie de 1 μm à 1 cm. L'invention est également relative à un procédé de préparation dudit matériau, à son utilisation pour la délivrance thermostimulée de substances actives, ainsi qu'aux compositions le renfermant.
