ABSTRACT:
An aqueous external dispersion comprising a wax dispersant and an organic crystal modifier composition dispersed through a continuous water phase is useful as a crystal modifier for petroleum or a petroleum-derived liquid. The dispersant comprises a non-ionic surfactant and is present in the dispersion in an amount sufficient to impart at least meta-stability to the dispersion. The dispersion has a viscosity at 25.degree. C. of less than about 50,000 centipoise.
