HLB and choice of water/oil soluble emulsifier
Hi!
I’m trying to formulate a cream(O/W emulsion). I have determined the required HLB of my oil phase and wanted to know, that when I try to match a blend of emulsifiers with this, should I go for oil soluble emulsifiers like PEG 40 or water soluble ones like polysorbates?Please help!
Thanks!
