Abstract
An organosilicon composition comprising 99.9 to 50% by weight of an alkylalkoxysilane and/or a condensate thereof and 0.1 to 50% by weight of an emulsifier mixture containing 0.01 to 20% by weight, based on the total amount of the emulsifier mixture, of an anionic emulsifier and 80 to 99.99% by weight, based on the total amount of the emulsifier mixture, of a nonionic emulsifier, the organosilicon composition forming a stable aqueous emulsion free from separation for a long period of time, having excellent waterproofness and excellent stability as an aqueous emulsion, having excellent permeability into civil engineering and construction materials, and imparting civil engineering and construction materials with excellent fungiproofness and antibacterial properties.
