Abstract: Stable composition of water-soluble organosiloxanes, obtained by reacting water-soluble amino-alkoxy-silane (A) with insoluble alkenyl-alkoxy-silane (B), then adding water and removing alcohol, using (A) and water in amounts such as to enable reaction of all alkoxy groups in (B) and adjusting to pH 2-6 with acid. A stable composition of water-soluble organosiloxanes obtained by (a) reacting a water-soluble, amino-functional alkoxysilane (A) with water-insoluble alkenyl-functional alkoxy-silane(s) (B), (b) adding water and (c) removing the alcohol formed. The amounts of amino-silane (A) and water used are such as to enable reaction of all the alkoxy groups in (B) and to give a composition from which essentially no alcohol is liberated by hydrolysis on dilution with water. This composition is adjusted to a pH of 2-6 by adding an optionally aqueous organic or inorganic acid during and/or after the reaction. An Independent claim is also included for a process as described above for the production of such compositions.
