Abstract
Solid particulate polyvalent metal carboxylic acid salt compositions particularly useful as polyvinyl chloride resin stabilizers are provided comprising at least one solid polyvalent metal carboxylic acid salt in dusting particulate form and a liquid epoxy fatty acid ester having a viscosity at 25.degree. C. within the range from about 100 to about 2000 cps, in an amount within the range from about 3% to about 20% by weight of the total composition, sufficient to render the particulate salt composition substantially nondusting, while maintaining the salt composition free-flowing, non-caking and non-tacky.
