A shape-retentive compacted article is produced from 1,3-dibromo-5,5- dimethylhydantoin particulate solids by (a) granulating the particulate soli ds without use of a binder, and (b) pressure compacting granulated 1,3-dibromo- 5,5-dimethylhydantoin granules formed in (a) that have a U.S. standard mesh size in the range of 80 mesh to 3 mesh, again without use of a binder. So fa r as is known, never before have 1,3-dibromo-5,5-dimethylhydantoin particulate solids been converted into a compacted form by any method.
