PROCESS FOR FORMING A LOW DENSITY DETERGENT GRANULE

A process for forming a low density detergent granule has the steps of providing from about 0.1% to about 6% of a hydrotrope, providing from about 22% to about 50 % crutcher mix moisture, providing from about 0.2% to about 8% of a water- soluble polymer with a molecular weight of at least about 10,0...

Summary:A process for forming a low density detergent granule has the steps of providing from about 0.1% to about 6% of a hydrotrope, providing from about 22% to about 50 % crutcher mix moisture, providing from about 0.2% to about 8% of a water- soluble polymer with a molecular weight of at least about 10,000 g/mol, providing fr om about 2% to about 20% sodium silicate having a SiO2:Na2O ratio of at least about 2:1, and the balance of adjunct crutcher ingredients, mixing the hydrotrope, crutcher mix moisture, polymer, silicate, and adjunct crutcher ingredients in a crutcher to form a slurry, injecting a gas into the slurry at a pressure of from about 6,000 kPa to about 13,000 kPa, and at a rate of from about 0.01% to about 0.25% and forming the slurry into a detergent granule. The slurry is substantially free of zeolite builder and phosphate builder an d the crutcher temperature is maintained at from about 40 .degree.C to about 95 .degree.C
