Abstract: We have found that long standing problems relating to the stability of organic materials in alkaline detergents, including the reversion or hydrolysis of condensed phosphate sequestrants in alkaline solid detergent compositions can be alleviated by the use of an organic composition having vicinal hydroxyls. Such a solid block detergent can be manufactured by a process in which a source of alkalinity, a functional material including a condensed phosphate sequestering agent, an organic compound having two vicinal hydroxyl groups, are combined in a pourable composition or liquid. Such a liquid can be introduced into a plastic capsule and solidified. During manufacture and solidification, we have found that the vicinal hydroxyl compound prevents substantial hydrolysis or reversion of the condensed phosphate maintaining effective hardness ion sequestration during the use of the detergent. The stabilizer can also stabilizes color, chlorine content and dispensing properties.

Abstract: We have found an alkaline warewashing detergent composition that can contain a critical amount of a nonionic rinse agent that when used in automatic warewashing machines permits the use of a potable water rinse without the addition of a separate rinse agent.

Abstract: There is provided an environmentally stable detergent article. Normally, hygroscopic caustic detergent materials can be made resistant to absorption of ambient humidity or water by introducing a barrier coating onto the caustic detergent. The barrier also renders the highly active alkaline material safe for human handling. The coated detergent article can further be enclosed in a film enclosure or wrapping which provides further protection for handling during production, shipment, storage and final end use. The coated article can be removed from any packaging material, inserted into a water spray-on dispenser and used to create a concentrated aqueous detergent for use in ware washing machines. In order to obtain control over dispensing, hydrophobic coatings can be nicked, split, peeled or partially removed using other means to provide an initial surface of caustic detergent exposed to the water spray.

Abstract: Tableted detergents are formed from a hydrated phosphate sequestrant, caustic, free water and, optionally, fillers by combining the products and tableting the components without permitting the tablets or detergent to exceed 50.degree. C. In a preferred embodiment where fillers are incorporated, all free water is combined with the phosphate sequestrants, both anhydrous and hydrated. After the water has been absorbed by the sequestrants, the filler and caustic can be added and the detergent tableted. The free water is bound sufficiently tightly to the phosphate sequestrant that it does not rapidly react with the anhydrous caustic, maintaining the temperature at less than 50.degree. C., which in turn prevents the water of hydration in the phosphates from reacting and thereby weakening the formed tablets. The tablets can also be formed by combining the filler with the phosphate sequestrants and water and subsequently adding caustic if the detergent is cooled and its temperature maintained below 50.degree. C.
