Novel, water-soluble antimicrobial compounds are provided which contain a sugar moiety linked to a nitrogen atom of substituted thiourea or a thiazole. The compounds have the general formula: ##STR1## and the pharmaceutically acceptable salts thereof wherein Su is a sugar moiety, i.e., mono- or polysaccharide and preferably glucosyl or acylated (i.e. C.sub.2 to C.sub.6 alkanoyl e.g. acetyl, propionyl, butyroyl etc. or aroyl e.g. benzoyl or C.sub.1 to C.sub.4 alkyl or alkoxy substituted benzoyl) ribosyl; and in Formula I, R.sub.1 and R.sub.2 are independently hydrogen, C.sub.1 to C.sub.8 alkyl or alkoxy; C.sub.1 to C.sub.8 .omega.-phenyl-(or substituted phenyl)-substituted C.sub.1 to C.sub.8 alkyl; C.sub.3 to C.sub.8 alkene, preferably allyl; ##STR2## wherein R.sub.3 and R.sub.4 are independently hydrogen or C.sub.1 to C.sub.8 alkyl, or the atoms to form a 5- or 6-membered heterocyclic [which may contain C.sub.1 to C.sub.4 alkyl, C.sub.1 to C.sub.4 alkoxy, halo (e.g., chloro, bromo or iodo), hydroxy, carboxamido, sulfonamido and the like] such as piperazino, methyl piperazino, pyrimidino, piperidino, morpholino, thiamorpholino, pyrrolyl, pyrrolidinyl, furyl, tetrahydrofuryl and the like, but only one of R.sub.1 and R.sub.2 is hydrogen, and in Formula II, R.sub.5 is oxy(C.sub.1 to C.sub.8)alkyl or substituted alkyl, phenyl or substituted phenyl or NR.sub.6 R.sub.7 wherein R.sub.6 and R.sub.7 are independently selected similarly as R.sub.1 and R.sub.2. The compounds are particularly useful in aqueous systems especially in cosmetic formulations for maintaining same in a septic state. Methods for making compounds of Formula I and II are also disclosed.
