Antibacterial and antifungal composition

摘要

An antibacterial and antifungal composition comprising (A) at least one member selected from the group consisting of dehydroacetic acid, sorbic acid and their alkali metal salts and (B) at least one member selected from the group consisting of o-phenylphenol and its alkali metal salts, p-chloro-m-xylenol, 2-(4-thiazolyl)-1H-benzimidazole, 8-hydroxyquinoline and its salts and chelates, methyl 1-(butylcarbamoyl)-2-benzimidazolecarbamate, tetrachloroisophthalonitrile and N-(fluorodichloromethylthio)phthalimide. The antibacterial and antifungal effects can be synergistically increased when the component (A) is employed in combination with the component (B).
