Abstract
A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO.sub.2. The densified carbon dioxide is in a temperature range of about -78.5.degree. C. to about 100.degree. C. and a pressure range of about 14.7 to about 10,000 psi. At least 0.1% by volume of a modifier is preferably present. The surfactant has a polysiloxane a branched polyalkylene oxide or a halocarbon group which is a functional CO.sub.2 -philic moiety connected to a CO.sub.2 -phobic functional moiety. The surfantant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
