ABSTRACT:
This invention relates to controlling corrosion in aqueous systems and more particularly to using certain calcium insensitive phosphonomethyl amine oxide compounds. The compounds of this invention are water soluble phosphonomethyl amine oxides having at least one oxidized tertiary amine group of the formula: ##STR1## and water soluble salts thereof and having a cloud point of at least about 25 ppm.
