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.展开更多
