Homogenizer, or simple mixer?
I want to currently formulating a facial cleanser with with oils. The concentration of oils i am currently using is 5.5%, so polysorbate is not the best option to simply solubize. Rather, I want to create an emulsion, kind of like a cream with 5.5% oils, and mix that into the surfactant phase. My question is, should I create the emulsion first with half the water, and mix this with a simple overhead mixer into the surfactant (with other 1/2 water) phase, or should I emulsify the oils into the water surfactant fase all-in-one using a homogenizer?
