ANTI-CORROSION DETERGENT COMPOSITIONS AND USE THEREOF IN CLEANING DENTAL AND MEDICAL INSTRUMENTS Russian patent published in 2010 - IPC C11D1/722 C11D3/30 C11D3/28 C11D3/36 A61L2/18 C23F11/06 

FIELD: chemistry.

SUBSTANCE: detergent composition has pH ranging from neutral to alkaline and contains an aqueous solution. The solution contains 0.005-10% surfactant with low foaming capacity; 0.005-10% corrosion inhibiting compound selected from C4-C16 alkylpyrrolidones and C1-C18 alkylamines and 0.01-15% modifying additive for preventing precipitation when metal ions react with the said surfactant. The cleaning solution contains a corrosion inhibitor and leaves a small amount of residue. The compositions are used not only at the washing stage of the cleaning cycle, but at one of the subsequent stages of the rinsing cycle in order to optimise cleaning and prevent rusting.

EFFECT: improved anti-corrosion and cleaning properties.
