Emulsion Properties of Mixed Tween20-Span20 in Non-Aqueous System
Oil-in-glycerol (O/G) emulsion was prepared in the presence of different weight ratios of mixed Tween20-Span20 surfactants. O/G emulsion was observed to form below 50 wt% of oil content at 3 wt% of mixed Tween20Span20 surfactants. Physical properties of the emulsion were determined by using a mi...

| Summary: | Oil-in-glycerol (O/G) emulsion was prepared in the presence of different
weight ratios of mixed Tween20-Span20 surfactants. O/G emulsion was
observed to form below 50 wt% of oil content at 3 wt% of mixed Tween20Span20
surfactants. Physical properties of the emulsion were determined by
using a microscope, particle counting and rheological measurement. An
attempt to correlate HLB values of mixed Tween20-Span20 with emulsion
stability was also carried out. |
