Wan Mahamod, Wan Rusmawati and Kuang Abdulah, Dzulkefly and Lim, Wen Huei and Suhaimi, Mohd Hamdan (2002) Emulsion Properties of Mixed Tween20-Span20 in Non-Aqueous System. Pertanika Journal of Science & Technology, 10 (2). pp. 153-160. ISSN 0128-7680


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.
