Abstract

AbstractThe effect of various additives on the hydrophile‐lipophile balance (HLB) of nonionic emulsifiers has been compared from the measurement of the effect of these additives on the phase inversion temperature (PIT) and on the emulsion inversion point (EIP). Theoretical aspects of PIT and EIP methods in the presence of various additives have also been discussed. Considerations based on the micelle formation and coalescence rates of emulsion globules in connection with the type and stability of emulsion formed using the PIT and EIP methods are presented. It was found that the combination of the PIT or EIP and the HLB‐value may be very useful in the selection of the most suitable emulsifier mixture in the presence of additives for a given emulsion system.
