Choose the correct answer (A to E). A cream has the following formula:Cetyl alcohol ('Required’ HLB for o/w 15) 9 gWhite soft paraffin (‘Required’ HLB for o/w 12) 8 gPropylene glycol 5 gEmulsifier 6.5 gWater to 100 gIf the surfactants used in manufacture of the cream were polysorbate 60 (HLB 14.9) and sorbitan monostearate (HLB 4.7), how much polysorbate 60 and sorbitan monstearate would be needed?Question 9Answera.3.36 g of polysorbate 60 and 2.63 g of sorbitan monostearateb.4.88 g of polysorbate 60 and 1.12 g of sorbitan monostearatec.None of the answers are correctd.1.12 g of polysorbate 60 and 4.88 g of sorbitan monostearatee.5.66 g of polysorbate 60 and 0.84 g of sorbitan monostearate

An o/w cream contains 9.5% (w/w) of emulsifier and has a required HLB of 11. Thesurfactants in the cream are sorbitan tristearate (Span 65) and polyoxyethylenesorbitan monopalmitate (Tween 40). If you prepare 120 g of the o/w cream,estimate the mass of each surfactant required to prepare the cream. [HLB (Span 65)= 2.1; HLB (Tween 40) = 15.6.
