Abstract
Particulate peroxygen compounds such as sodium percarbonate are coated with a copolymer of vinylidene chloride and another copolymerizable monomer. These coated compounds can be used in detergent mixtures. The coating of peroxygen compound with such films protect the compound from the effect of decomposition by wet air during storage while it permits liberation of the peroxygen compound in an aqueous washing solution.
