Title (EN) METHOD FOR PRODUCING AND USING ACTIVE PRINCIPLES OF LIMESTONE
(FR) OBTENTION ET UTILISATION DE PRINCIPES ACTIFS DES CALCAIRES
Abstract:
(EN) The present invention relates to a method for extracting organic molecules and/or organic minerals from a limestone material, including placing said limestone material in contact with a solution including at least one organic solvent, water and at least one acid, as well as to the organic molecules and/or organic minerals produced by the method. The products produced by the method can be used, for example, in therapeutic and non-therapeutic fields, in particular the agri-food, cosmetic and medical fields.
(FR) La présente invention se rapporte à un procédé d'extraction de molécules organiques et/ou organominérales à partir d'un matériau calcaire comprenant la mise en contact dudit matériau calcaire avec une solution comprenant au moins un solvant organique, de l'eau et au moins un acide, ainsi que les molécules organiques et/ou organominérales obtenues par le procédé. Les produits obtenus par le procédé trouvent une application, par exemple dans les domaines thérapeutiques et non thérapeutiques, notamment agro-alimentaire, cosmétiques et médicales.
