Making Hair wax and have been told that:
Current process is: Oil phase + Water phase (Both aroud 180F) Mixed and cooled.
Liquid PVP/VA Copolymer: should be mixed in during Cool down phase around 120F.
Powder PVP: Should be mixed in during water phase at 180F.
Does Mixing PVP powder in water at 180F reduce it's hold/fixative properties?
