Abstract
A stability enhancement agent for use in a solid detergent and solid detergent compositions is described. Stability enhancement is provided by a hydratable salt, water and a polyepoxysuccinic acid or polyepoxysuccinic acid metal salt binding agent forming a dimensionally stable composition. Preferred polyepoxysuccinic acid or polyepoxysuccinic acid metal salts have a molecular weight of between about 400 and about 1,500 g/mol. The stability enhancement composition for use in a solid detergent and solid detergent compositions are preferably biodegradable and substantially free of phosphorus and NTA.
