摘要：
The invention relates to the use of alkoxyhydroxy fatty acids and the salts thereof having the general formula (I) ##STR1## wherein R.sup.1 represents a straight chain alkyl radical or a straight chain alkenyl radical having from 6 to 8 carbon atoms,R.sup.2 represents a straight chain or branched chain alkyl radical having from 1 to 18 carbon atoms, or a straight chain or branched chain alkenyl radical having from 2 to 18 carbon atoms,M represents hydrogen or an organic ammonium radical having one or more alkyl radicals or hydroxy alkyl radical attached to the nitrogen atom, andm represents an integer having a value of from 3 to 13,in an amount of from 0.01 to 10% by weight, based on the weight of oil, as corrosion inhibitors in oils and oil-containing emulsions.
