ABSTRACT:
A system for dry cleaning soils from fabrics is described which contains densified carbon dioxide combined with a selected surfactant. The densified carbon dioxide is used in a temperature range of about -78.5.degree. C. to about 100.degree. C. and a pressure range of about 14.7 psi to about 10,000 psi. The surfactant is selected from one of two groups of compounds having a formula ##STR1## as described in the text or a second group of siloxane compounds having a formula [AB].sub.y as described. A process for using the dry cleaning system is also described.
