are restricted to monoanionic and monocationic ion pair compounds when x 1 the invention is also applicable to polyanionic and polycationic compounds see example vii below when x is greater than 1 with the proviso that if one reactant is polyanionic or polycationic the other reactant of opposite charge must be monocationic or monoanionic respectively typical examples of anionic and cationic silicone reactants are given in u s pat nos 3 389 160 patented june 18 1968 3 507 897 patented apr 20 1970 3 658 867 patented apr 25 1972 and 3 660 452 patented may 2 1972 all incorporated herein by reference the compounds of the instant invention are useful in solution using aqueous and non aqueous solvents therefore it is not necessary to isolate the compositions of the invention instead the compounds of the invention can be used in the solutions in which they are prepared since the compounds of the invention are useful in the presence of the surface inactive metallic halide by products of the invention it is not necessary to remove these halides from solution the organosilicon compounds of the present invention are useful as aqueous surface tension depressants having limiting surface tensions in water of 20 8 to 22 5 dyne cm with very low critical micelle concentrations of 0 0005 to 0 05 weight percent at these low concentrations they are much more effective aqueous surface tension depressants than conventional ionic silicone or organic surfactants the compounds of the invention are potentially useful in a wide variety of other surface related areas such as water washable lubricants mold release agents wetting agents bactericides detergent additives foam stabilizers anti static agents and as additives to coatings paints and polishes in addition the compounds.
