ABSTRACT:
Transparent aqueous organopolysiloxane compositions comprising (A) a salt of a water-soluble organic or inorganic acid and a polysiloxane, which contains in addition to the other siloxane units siloxane units containing SiC-bonded monovalent radicals having basic nitrogen atoms in an amount of at least 0.5 percent by weight, based on the weight of the polysiloxane; and (B) an organic silicon compound having basic nitrogen atoms in an amount of from 0 to 0.5 percent by weight, based on the weight of the organic silicon compound; and when constituent (B) does not contain at least one organic silicon compound having a molecular weight greater than 600 g/mol in an amount of at least 0.1 part per part by weight of contituent (A), then an organic solvent (C) is present in an amount up to about 5 percent by weight based on the weight of constituent (A), in which the organic solvent is soluble in water up to about 1 part by weight per 100 parts by weight of water at 20.degree. C. and 1020 hPa (abs.) and is free of halogen atoms.
The organopolysiloxanes may contain Si-bonded hydrogen as well as at least one SiC-bonded radical having a basic nitrogen atom in one and the same molecule.
