摘要/Abstract

摘要： An innovational test method was developed on the basis of redefinition of the emulsion
stability. The stability was characterized by relative volume percentage of disperse phase
demulsified thoroughly from the top part and the bottom part of an emulsion sample, each
weighting the same amount, after being settled for a given time at constant temperature.
Three series of emulsions were prepared and tested successfully, which were emulsions of
paraffin oil and water stabilized with polyoxyethylene lauryl ether series (AEO3 and AEO9)
at various HLBs, and emulsions of rapeseed oil and water stablized with sorbitan monoleate
(Span80) and each of polyoxyethylene (20) sorbitan carboxylic esters (Tween20, Tween40,
Tween60, Tween80 and Tween85) at different HLBs. It proved that this method is especially
workable while the boundaries are opaque in a wide range of HLBs and is capable of offering
an accurate optimum HLB.
