Abstract

An emulsifier mixture for use in the production of phase inversion temperature (PIT) emulsions is provided. The emulsifier mixture comprises fatty acid ethoxylates and partial glycerides which enable PIT emulsions to be produced at a given phase inversion temperature irrespective of the polarity of the oils, allowing for the emulsifying of a broad range of oils irrespective of their character, under the same conditions.
