Patent Images
1. A solid detergent composition comprising:
- between about 0.1 wt-% and about 20 wt-% a phosphinosuccinic acid derivative comprising a phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid adducts;
between about 0.1 wt-% and about 50 wt-% water;
between about 40 wt-% and about 90 wt-% sodium carbonate; and
between about 0.5 wt-% and about 10 wt-% surfactant;
wherein the solid detergent provides a use solution having a pH between about 9 and 12.5,wherein the solid detergent composition has less than about 2 wt-% phosphate, andwherein the solid detergent composition is dimensionally stable and has a growth exponent of less than 3% if heated at a temperature of 122°

Abstract
Stability enhancement agents for use in a solidification matrices and solid detergent compositions are described. Stability enhancement is provided by a hydratable salt, water and phosphinosuccinic acid (PSO) derivative binding agents forming a dimensionally stable composition. Preferred phosphinosuccinic acid (PSO) derivatives include phosphinosuccinic acid and mono-, bis- and oligomeric phosphinosuccinic acid (PSO) derivatives. The stability enhancement composition for use in a solid detergent and solid detergent compositions are preferably biodegradable and substantially free of phosphate and NTA-free.
