Abstract
Acetylenic alcohols and diols have been found which are soluble in liquid/supercritical CO.sub.2 and exhibit surface active properties. These alcohols and diols act as surfactants by lowering the surface tension between CO.sub.2 and mobile CO.sub.2 -phobic substances which are contacted with the CO.sub.2.
