ABSTRACT:
An active-halogen bleach such as dichloroisocyanurate encapsulated in a coating of dihydratea synthetic detergent such as sodium octyl sulfonate. The capsule may further comprise an initial coating of a soluble inorganic detergent builder or filler such as an alkali metal phosphate or sulfate. The capsule is stable in highly alkaline environments such as detergent compositions.
Solid cast detergent-bleach composition having minimal bleach degradation comprising an alkaline hydratable chemical such as sodium hydroxide, a hardness sequestrant such as sodium tripolyphosphate, water of hydration and encapsulated active-halogen bleach formed in accordance with this invention. Optionally the detergent-bleach composition may contain a polyelectrolyte such as polyacrylate.
