O/W/O Multiple Emulsions Containing Amazon Oil: Babassu Oil (Orbignya oleifera)

Abstract

The aim of this work was to formulate O/W/O stable multiple emulsions containing Babassu oil and to evaluate the physical stability. Babassu is the popular name given to the palm tree (Orbignya sp) that occurs in the Amazon forest. The multiple emulsions were prepared using the two-step procedure. To improve the stability the properties of the formulation ingredients were explored. The investigated formulations were characterized and their stability over the time was evaluated by preliminary and accelerated stability. The macroscopic and microscopic characteristics, the values of the apparent viscosity, both consistency and flow index, and hysteresis areas during aging, indicated good long-term stability of these formulations.
