Abstract: A cleaning system comprising a reservoir of cleaning solvent, a fabric article treating vessel and a filtration device for removing contaminants from the cleaning solvent. The filtration device comprises an absorbent material having a water absorbing capacity of at least about 50 g of water/g of absorbent material and an adsorbent material having an adsorbent capacity at least about 200 mg contaminants per gram of adsorbent material. A method for using the same is also disclosed.

Abstract: Process for treating lipophilic fluids employing filters, more particularly, multifunctional filters that are capable of removing as well as adding components to lipophilic fluids being filtered are provided by the present invention.

Abstract: A process for making granular detergent compositions or components comprising from about 35% to about 85% by weight of a surfactant system comprising a mixture of polyhydroxy fatty acid amide and ethoxylated nonionic surfactant. The surfactant system is in the solid phase at temperatures of 25.degree. C. and below, and has a softening point from above 25.degree. C. to 100.degree. C. Additionally, the surfactant system has a viscosity profile whereby its viscosity is at least about 20,000 cps at a temperature of 10.degree. C. above the softening point, and less than about 10,000 cps at a temperature of 30.degree. C. above the softening point, all viscosities being measured at a shear rate of 25 s.sup.-1.
