PVP/VA & PVP Formulation Phase Temperatures

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?

Thanks!

  • no, it's very heat-resistant (as are VP/VA copolymers)
    UK based formulation chemist. Strongest subjects: hair styling, hair bleaches, hair dyes (oxidative and non-oxidative) I know some stuff about: EU regulations, emulsions (O/W and W/O), toothpaste, mouthwash, shampoos, other toiletries
  • In my formulations with PVP, I have always added it to the water phase first thing along with fixative and heated to 82c-87c/180f/190f then mixed with oil phase. I've also done a one pot, mixing water and oil phases together and bringing to temp.

    As Bill stated, it is pretty heat resistant.

    It sounds like both are very heat resistant. I may try adding the pvp/va in the water phase next time instead of the cool down phase. 

    Thanks!
