Abstract: The invention provides a composition for improving the water repellency of a substrate, like a construction substrate for example a building component. This composition contains a mixture formed by combining: water, at least one water-repellent silicon-containing compound, which is a silicone resin, an alkoxysilane or a polysiloxane, a siloxane surfactant containing an alkylpoly(ethyleneoxy)siloxane group and an alkyl siloxane group, where the alkyl group contains 1-6 carbon atoms. The composition can be used on previous treated substrates or more generally on substrates which are difficult to wet or penetrate.

Abstract: Oil-in-water (O/W) and water-in-oil (W/O) emulsions and microemulsions containing elastomeric silanes or siloxanes preferably having quaternary ammonium groups are generally made by reacting organic quaternary ammonium compounds having epoxide groups or halohydrin groups, with silanes or siloxanes having amino groups. The reaction is carried out in an aqueous polar phase containing a crosslinking agent and surfactant. The emulsions and microemulsions are especially useful for treating hair, skin, or the underarm.
