MANUFACTURE OF SOLID, CAST NON-SWELLING DETERGENT COMPOSITIONS

摘要

A method of manufacturing a solid, cast detergent composition which includes a hydratable chemical capable of combining with water under differing conditions to form at least two distinct hydrated forms which have different densities, such as sodium carbonate, so as to prevent swelling of the cast composition. The process controls the concentration of hydratable chemical, based upon hydratable chemical and water, and the temperature of the mixture throughout the process to minimize formation of the more dense hydrated form of the hydratable chemical.
