PURPOSE:To obtain the subject stainproofing agent comprising tetralin and a dispersant, having excellent anti-oxidizing effects, showing sufficiently preventing effects on stain even in a system mixed with dissolved oxygen, stably operating a plant and avoiding danger accompanying urgent stop. CONSTITUTION:The objective stainproofing agent comprises (A) tetralin and (B) a dispersant composed of a mixture of (i) a polyalkyl (meth)acrylate having about 1,000-10,000 molecular weight and (ii) a polyethylenepolyamine naphthenic acid amide of the formula (R<1> is 10-15C hydrocarbon; (n) is 1-5; (m) is 1-10). This agent reduces energy and maintenance cost. |
