Abstract

The use of hollow particles of hybrid aluminosilicates of imogolite or allophane type, characterized in that they have their external surface functionalized with Al—OH units and their internal surface functionalized at least in part with Si—R units, with R representing a nonhydrolyzable unit, preferably a hydrocarbon unit, as vehicle for one or more hydrophobic substances, in particular considered in the oil industry, the hydrophobic substances being chosen from any compound containing a linear or branched aliphatic chain having at least 4 carbon atoms, surfactants, biocides and methane clathrates inhibitors.
