The aqueous compositions for rendering absorbent materials oil-repellent and water-repellent consist essentially of (A) an organosilicon compound, (A1) a C1-C20-alkyl-C1-C6-alkoxysilane, (A2) an organopolysiloxane containing C1-C6-alkoxy groups and optionally groups selected from hydroxyl groups and C1-C30 hydrocarbon groups which optionally contain basic nitrogen, or mixtures of (A1) and (A2), (B) an organofluorine compound consisting of fluorine and carbon atoms and optionally chlorine, hydrogen, oxygen sulfur, silicon, phosphorus and/ or nitrogen atoms, and containing CF bonds, (C) a surfactant and (D) water.
