MORALES, C. J.; RIEBEL, U.; GUZMAN, N.M.  e  GUERRA, M.. Formulation of water in paraffin emulsions. Lat. Am. appl. res. [online]. 2011, vol.41, n.2, pp.105-112. ISSN 0327-0793.

In this work, the effect of surfactant content, water content, HLB value, alcohol content, salinity, emulsion volume and mixing properties on water in paraffin emulsion stability was studied. Emulsion stability was determined by the extent of water and oil resolved after 30 days. After finishing the variables scans, the most appropriate formulation conditions were established, and a formulation protocol was defined. Emulsion density and apparent viscosity were measured, and viscosity was modeled by the Power Law.
