    摘要: A method of dry cleaning fabrics using a dry cleaning system is described. The system comprises densified carbon dioxide, preferably in a liquid phase, and a selected surfactant which is soluble in the densified CO.sub.2. 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 surfactant either exhibits an HLB of less than 15 or has a ratio of siloxyl to substituted siloxyl groups of greater than 0.5:1.
