Qualitative observations regarding the solubility of over 130 surfactants and related molecules in carbon dioxide at 50 °C and pressures of ∼ 100–500 bar are presented. The solubility properties of some surfactant classes are discussed. Related comments on the behavior of the surfactant/carbon dioxide systems when water is added, regarding the possibility of microemulsion formation, are also presented.
