Figure 16. Mean droplet size variations of HF and CJSO emulsions in the HLB range 3.70–16.70 (sorbitan sesquioleate: polysorbate 20) after 1 week storage at room temperature (n = 3 ±SD). Figure 15. Droplet sizes of CUFO and CUPO emulsions with (A) surfactant (polysorbate 60: polysor- bate 20) HLB range 14.90–16.70, and (B) surfactant (sorbitan sesquioleate: polysorbate 20) HLB range 13.45–16.70, which were measured by particle size analyzer after 1 week storage at room temperature (n = 3 ±SD).
