Antimicrobial compositions, method of inhibiting the growth of microorganisms and metal working fluid compositions containing these antimicrobial compositions.

摘要

Antimicrobial compositions for inhibiting the growth of microorganisms in an aqueous fluid medium comprising an admixture of a condensation product of 5,5-dimethylhydantoin and formaldehyde with a chelating agent. A method for inhibiting microorganism growth in aqueous fluid media, particularly such media containing fatty oil or petroleum base components and modified metal working fluids also described.
