The present invention relates to a novel thixotropic oily vehicle comprising from 0.2% to 5% (w/w) of a colloidal silica and from 0.2% to 5% (w/W) of a hydrophilic polymer in an edible oil. The interaction between the hydrophyli c polymer and the colloidal silicon dioxide in the above concentration ranges enables to keep the amount of the latter component at a low concentration, b y nevertheless conferring on the solution enough thixotropy and a low viscosit y under shear. The invention also relates to capsules filled with the above fi ll mass.
