Abstract

1,3,5-Triazine-2,4,6-tris-alkylaminocarboxylic acid derivatives of the general formula (I): 1,3,5-triazine-2,4,6-trisNH--(CH.sub.2).sub.n --CO--O--R.sup.1 ! are employed as biocidal or biostatic agents in aqueous systems, in particular in cooling lubricants. Fungicides, for example pyrithione or derivatives thereof and/or N-alkyl-diazenium dioxide salts, can be added to the aqueous systems. 0.05 to 0.40% by weight of the 1,3,5-triazine-2,4,6-alkylaminocarboxylic acid derivatives and 0.0001 to 0.2% by weight of fungicides are sufficient to maintain the biocidal or biostatic actions.
