Non-aqueous wax/solvent systems of industrial relevance for the manufacture of paste polishes have been investigated. These mixtures have been modelled using a paraffin wax of Japanese origin (Nippon Seiro 140/145°F) in a solution of pure heptane to which dopant components are added.The stability of any resulting gel has been assessed via solubility studies and measurement of the solvent vapour pressure. A new technique for the measurement of vapour pressure in these systems has been developed. The operation of the apparatus has been made almost completely automatic by the use of modern control units.Complementary analytical techniques such as Differential Scanning Calorimetry and Nuclear Magnetic Resonance have been used to augment the data where appropriate and the structure of these pastes has been investigated with the use of Optical Microscopy.
