Permanganate-containing pellets for gradual release or permanganate comprise an integrated body of a hydratable, self-curing cement in cured, hydrated form, and finely-divided particles of a water-soluble permanganate salt in substantially uniform distribution therein. The pellets are formed from a mixture of the permanganate salt, hydratable self-curing mineral cement, and water.

Permanganate-containing pellets and method of manufacture

A method is provided for selectively bleaching dyed, bleachable cotton garments. The garments are tumbled in damp condition with reuseable pre-formed solid pellets of limited porosity having abradable surfaces. The pellets comprise substantially water-insoluble cemented aggregates of mineral particles with a finely-divided particulate bleaching aent imbedded therein. The bleaching agent, which preferably is substantially uniformly distributed in the pellets, bleaches the garments by surfaces of the pellets wearing away during the garment tumbling to release the bleaching agent as the pellets contact the garments.
