Q: Increasing the proportion of the disperse phase of an emulsion by more than 60% may lead to
  • A. Cracking
  • B. Frothing
  • C. Phase inversion
  • D. Creaming
Correct Answer: Option C - If the oil level is increased to 60% it will favor the formation of a W/O emulsion this is because it becomes increasingly difficult to pack the oil droplets into proximity without having them combine as their concentration is increased. The higher phase inversion temperature the more stable is the oil-in-water emulsion at ambient temperature.
C.
