The use of oxathiazolones of formula is described, R1 is C1-C16alkyl, C2-C16alkenyl or C5-C8cycloalkyl, each unsubstituted or substituted by halogen, -CN, -NO2, -C=O, -C=S, -NR2, -OR3, -SR4, -SO2R5, -COOR6 or by a 1,3,4-oxathiazol-2-one radical; C6-C10aryl unsubstituted or substituted by one or more C1-C5alkyl, C6-C10aryl, halogen, hydroxy, acyl, -CN, -CF3, -NO2, -NR2, -OR3, -SR4, -SO3H, -SO2R5, -COOR6 substituents or by a 1,3,4-oxathiazol-2-one radical; or a 5- or 6-membered heterocyclic radical; R2 and R3 are each independently of the other hydrogen; C1-C5alkyl; C6-C10aryl, or acyl; R4 is hydrogen; C1-C5alkyl; or C6-C10aryl; R5 is C1-C5alkyl; or C6-C10aryl; R6 is hydrogen; C1-C5alkyl; or C6-C10aryl, in the antimicrobial treatment of surfaces. The compounds exhibit a pronounced action against pathogenic gram-positive and gram-negative bacteria, and also against yeasts and moulds.
