The dry blends comprise a powdery or finely-divided active ingredient such as a pharmaceutical, dietary supplement, agricultural chemical, water-treating agent or biocidal agent, and a micronized synthetic polyolefin-based hydrocarbon wax and/or a micronized sythetic polyfluorocarbon wax that is compatible with the active ingredient. Shape-retentive compacted compositions are formed by pressure compacting such blends. Preferred active ingredients are 1,3-dihalo-5,5-dialkylhydantoins and profen pharmaceuticals such as naproxen. |
