PURPOSE:To ensure solubility in water, to prevent the emission of an offensive odor and to enhance corrosion preventing effect by incorporating a compd. such as 3-(gamma-aminopropyl)hydantoin represented by a specified general formula as an active component. CONSTITUTION:This corrosion inhibitor contains a compd. represented by general formula I or II [where each of R1 and R2 is H or lower alkyl and X is H or -(CH2)3NH2)] as an active component. The compd. represented by the formula I is typically 3-(gamma-aminopropyl)hydantoin. The compd. represented by the formula II is typically 1,3,7-triazabicyclo-[4,3,0]-non-7-en-2-one.
