A new class of chemical compounds having the formula X-R-O-C-S2O3-M PARALLEL 0 in which X is hydrogen or the grouping -O-C-S2O3-M, PARALLEL O R is selected from the group consisting of (1) straight and branched open chain saturated and unsaturated aliphatic hydrocarbon radicals having from 1 to 18 carbon atoms in which the branching occurs at a carbon atom not directly bonded to the oxygen atom, (2) mono- and poly-oxaalykylene radicals having from one to five oxaalkylene groups in which each alkylene group contains from 2 to 10 carbon atoms and in which the total number of carbon and oxygen atoms is from 5 to 26, and (3) corresponding radicals in which at least one hydrogen atom is replaced by fluorine, AND M is selected from the group consisting of alkali metals and alkali earth metals. These compounds act as acylating agents for amino and hydroxyl groups, for which purpose they can be used in aqueous solution. They are also effective as cross-linking agents for polymers containing amino or hydroxyl groups, as bacteriostatic and fungistatic agents and as antiperspirants.
