Implication

Experimental study reveals that crossing a cubic liquid crystal phase minimizes droplet size in ionic nano-emulsions, highlighting key formulation mechanisms for low-energy emulsification.

Key Points

Investigate whether the low-energy emulsion inversion point method can produce oil-in-water nano-emulsions within an ionic surfactant system and identify the factors governing droplet size.
Applied the emulsion inversion point method to an ionic system containing water, potassium oleate, oleic acid, C12E10, and hexadecane.
Combined phase diagram analysis, rheological measurements, and experimental designs to evaluate the effects of formulation variables, water addition rates, and stirring speeds on droplet size.
Producing minimal droplet sizes required crossing a direct cubic liquid crystal phase and maintaining the system in that phase long enough to dissolve all hexadecane prior to dilution.
Compositions with a broad liquid crystal zone extending to high water contents produced the smallest droplets independent of agitation rate or addition speed.
Compositions displaying narrower liquid crystal zones relied on elevated agitation rates or slower addition rates to ensure complete oil incorporation.
