  • Patent number: 6461387
    Abstract: A system for dry cleaning soils from fabrics comprising densified carbon dioxide and a surfactant in the densified CO2. The densified carbon dioxide is in a temperature range of about −78.5° C. to about 100° 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 CO2-philic moiety connected to a CO2-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.
