摘要： A suds suppressor composition 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 about 20 to about 12,500 cs, and(ii) PDMS having a viscosity of at least about 25,000 cs wherein the blend has a viscosity of at least about 18,000 cs,the suds suppressor being dispersed in a water-soluble or water-dispersible organic carrier comprising:(i) from about 1% to about 100% of a first carrier component melting in the range of about 38.degree. C. to about 90.degree. C. andfrom 0% to about 99% of a second carrier component which is an ethoxylated nonionic surfactant melting in the range from about 5.degree. C. to about 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.
