The present invention refers to an additive integral composition for internal treatment of steam generators, which is characterized in that it comprises a scale dispersing-inhibiting and anti-foaming agent to disperse contaminants contained in feeding water such as: calcium and magnesium salts, as well as iron oxide and silica, in a sufficient amount so as to protect metallic surfaces of a steam generator condensate returning system, said amount being of from about 4 to about 20 percent by weight; an oxygen sequestering additive, which will be eliminated in the steam generator feeding water in an amount of from about 0.001 to about 0.05 percent by weight; and deionized water in a sufficient amount so as to obtain 100 percent by weight.
