CA 2264783

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 metastability to the dispersion. The dispersion has a viscosity at 25°C of less than about 50,000 centipoise.

Dispersion externe aqueuse comprenant un agent de dispersion de la cire et une composition d'un agent modificateur de cristaux organiques dispersée dans une phase aqueuse continue, cette dispersion étant utile comme agent modificateur de cristaux pour le pétrole ou un liquide dérivé du pétrole. L'agent de dispersion comprend un tensioactif non ionique qui est présent dans une quantité suffisante, ce qui permet de conférer au moins une métastabilité à la dispersion. Cette dispersion a une viscosité inférieure à environ 50 000 centipoises à 25 DEG C.
