The invention relates to a method for manufacturing a composite based on complexes of controlled stability over time, comprising, on the one hand, a fibrous inorganic matrix having tunnels and, on the other hand, one or more organic compounds incorporated into said tunnels. The invention is characterized in that it comprises the following steps, in which: the fibrous inorganic matrix having tunnels and the organic compound or compounds are provided; the fibrous inorganic matrix having tunnels is mixed with the organic compound or compounds so that said organic compound or compounds are incorporated into the tunnels of the fibrous inorganic matrix; the retention of the organic compound or compounds in said tunnels and their release therefrom by heating said mixture obtained, at a chosen temperature for a defined time, are controlled. The invention applies in particular in a preparation intended for cosmetic, pharmacological, nutri-therapeutic and agri-foodstuff, phytosanitary, petroleum or electronic usage or else in paints.
Image L'invention concerne un procédé de fabrication d'un composite à base de complexes de stabilité contrôlée dans le temps comprenant, d'une part, une matrice inorganique fibreuse à tunnels et, d'autre part, un ou plusieurs composés organiques incorporés dans lesdits tunnels. L'invention se caractérise en ce qu'elle comporte les étapes suivantes selon lesquelles : on fournit la matrice inorganique fibreuse à tunnels et le ou les composés organiques; on mélange la matrice inorganique fibreuse à tunnels et le ou les composés organiques de manière à ce que ledit ou lesdits composés organiques soient incorporés dans les tunnels de la matrice inorganique fibreuse; et on contrôle le maintien du ou des composés organiques dans lesdits tunnels et leur relargage en chauffant ledit mélange obtenu à une température choisie pendant un temps déterminé. L'invention s'applique en particulier dans une préparation destinée à un usage cosmétique, pharmacologique, nutrithérapeutique et agro-alimentaire, phytosanitaire, pétrolier, électronique ou encore dans les peintures.
