ABSTRACT:
The present invention relates to a corrosion inhibitor for bathing waters which contain chlorides and sulfates, in particular sodium chloride and magnesium sulfate, that reduces the corrosion effect of such bathing water on metallic materials, in particular steels (structural steel) and brass. The corrosion inhibitor of the present invention is based on a composition comprising phosphates, zinc chloride and aminotrimethylenephosphonic acid.
