Title:
CORROSION INHIBITOR FOR HYPOCHLOROUS ACID AQUEOUS SOLUTION, BACTERICIDAL DETERGENT HAVING CORROSION INHIBITING EFFECT, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/158522
Kind Code:
A1
Abstract:
The present invention provides a corrosion inhibitor which is for a hypochlorous acid aqueous solution and imparts a corrosion inhibiting effect of suppressing the generation of rust in a contacted metal surface to a hypochlorous acid aqueous solution, the corrosion inhibitor being characterized in that an effective component substantially includes only: an A component composed of (A1) a metal salt of formic acid and/or (A2) a metal salt of saturated carboxylic acid in which the number n of carbon atoms contained in the molecule is at least 2, the valence v of the acid is 1 or 2, and the value n/v obtained by dividing the number n of carbon atoms by the valence v of the carboxylic acid is 2-6; and a B component composed of a nonionic surfactant, wherein the mass ratio B/A of the B component to the A component in the effective component is 0.005-10.0.
