Abstract: The microbicidal agents consist esentially of 5 to 50% by weight of the salt of an alkyl-di-guanidine of the formula in which R' and R'' denote hydrogen or C8-C18-alkyl, and R' and R'' may not simultaneously be hydrogen, m denotes a number from 2 to 6 and n denotes 0 to 1, 5 to 50% by weight of a quaternary ammonium compound of the formula in which R1 denotes C8-C22-alkyl or C8-C22-alkenyl, R2 and R3 denote C1-C4-alkyl or C2-C3-hydroxyalkyl and R4 denotes hydrogen or methyl, or R1 and R2 denote C8-C12-alkyl, R3 denotes C1-C4-alkyl or C2-C3-hydroxyalkyl and R4 denotes hydrogen or methyl, X in both cases denotes a number from 1 to 3, preferably from 1 to 2 and in particular 1,5, and A(-) denotes an anion of a carboxylic acid from the group comprising propiionic acid, lactic acid, glycolic acid, tartronic acid, malic acid, tartaric acid, citric acid, maleic acid and benzoic acid, and, as the remainder, water and/or a lower alcohol or a water-soluble glycol.
