Abstract: This invention relates to ion-pair-containing siloxane compounds that are extremely effective as surface tension depressants. The compounds of the present invention contain both anionic and cationic substituents and can be formed by metathesis reactions between metallic salts of anionic silicone or organic surface-active compounds and halide salts of quaternary ammonium silicone or organic surface-active compounds. The compounds of the invention are relatively pH insensitive when compared to siloxanes bearing anionic and cationic substituents that are formed by proton transfer. Thus, the organosilicon compounds of the invention will remain stable despite changes in pH of the mixture in which they are present.
