Abstract

Processes for preparing superbasic zinc soaps are disclosed. The processes described comprise: (a) providing a basic zinc carbonate; (b) providing at least one organic carboxylic acid; and (c) reacting the basic zinc carbonate and the at least one organic carboxylic acid at a temperature of from about 100° C. to about 200° C. The use of such soaps for stabilizing halogen-containing plastic compositions is also described.
