Abstract : Certain solubility-linked physical properties of soap/ solvent systems have been shown to be functions of the solubility parameter of the solvent. The lowest critical solution temperatures for zinc and lead stearates occur in solvents having a solubility parameter of 8.9. Maximum swelling of lithium and sodium stearate/solvent systems occurs at a solvent solubility parameter of 9.3. In addition, the gel/jelly-or-sol transition temperatures for aluminum dilaurate/solvent systems have been shown to be an approximately linear function of solvent solubility parameter. A qualitative explanation for the observed results is based upon an analogy to high polymer/solvent systems. (Author)
