6. A 60 mL emulsion has an oil phase consisting of 8.4 g cetyl alcohol (HLB=15), 0.6 g white wax (HLB=12), and 6.0 g white petrolatum (HLB =12). A 5.0% w/v blend of sorbitan monooleate (HLB=4.3) and polyoxyethylene sorbitan monooleate (HLB=15.0) is used as the emulsifying system. Calculate the total HLB and the amount of each emulsifier required to prepare the emulsion. 6.
