<p>SUDS SUPPRESSOR COMPOSITIONS AND THEIR USE IN DETERGENT COMPOSITIONS A suds suppressor compositon comprising, as suds-suppressor, a blend of: (i) a high shear mix of polydimethylsiloxane (PDMS) and hydrophobic silica, the PDMS having a viscosity of from 20 to 12,500 cs, and (ii) PDMS having a viscosity of at least 25,000 cs wherein the blend has a viscosity of at least 18,000 cs, the suds suppressor being dispersed in a water-soluble or water-dispersible organic carrier comprising: (i) from 1% to 100% of a first carrier component melting in the range from 38.degree.C to 90.degree.C and (ii) from 0% to 99% of a second carrier component which is an ethoxylated nonionic surfactant melting in the range from 5.degree.C to 36.degree.C. The compositions are particularly suitable in high-active containing heavy duty detergent compositions and provide improved foam regulation across the range of wash temperature, product usage, soil, load and rinsing conditions.</p> |
