The objective of this work was to obtain water-in-oil (w/o) emulsions with polyglycerol polyricinoleate (PGPR) as emulsifier and to study the effect of the addition of calcium in the dispersed aqueous phase on the stability of these systems. Emulsions were formulated with 0.2, 0.

Synopsis of recent research by authors named "Andres L Marquez"

  • Andres L Marquez's research primarily focuses on the formulation and stability of water-in-oil (w/o) emulsions, particularly using polyglycerol polyricinoleate (PGPR) as an emulsifying agent.
  • One of his significant studies investigates how the addition of calcium salts to the aqueous phase impacts the stability of these emulsions, indicating the importance of ionic components in emulsion formulation.
  • The findings suggest that varying concentrations of calcium and surfactants can significantly affect the performance and stability of w/o emulsions, which has implications for various applications in food and pharmaceutical industries.
