Dual phase questions
Hi all,
I’m looking to formulate a dual phase hair spray, with oil phase being milky.1. How can i make oil phase milky? I found this formulation from Dow Corning and I’m seeing they have added Polysorbate 20 @ 1% in the oil phase…the rest are silicones.What’s the function of polysorbate 20 in this formula?2. I’m seeing that sodium chloride is typically added in dual phase formulas. I understand that in W/O formulations, salt is added to stabilize emulsion, but don’t understand it’s function in a dual phase.Thanks in advance!
