Abstract

The invention proposed is an aqueous emulsion comprising the components PA0 (A) organosilicone compositions selected from PA0 (A1) C.sub.1 -C.sub.20 -alkyl-C.sub.2 -C.sub.6 -alkoxysilanes and PA0 (A2) organopolysiloxane containing alkoxy groups, PA0 (B) organopolysiloxane containing, one or more siloxane units having SiC-bonded radicals containing basic nitrogen, with the proviso that the amine number of the organopolysiloxane is at least 0.01, and PA0 (C) an emulsifier. The said emulsions are used for making porous mineral building materials hydrophobic.
