  Heat stability of vitamins used in cosmetics and potential problems of cool down addition

  Posted by Zink on June 7, 2014 at 12:59 am

  Wondering whether the following vitamins can be added to the hot approx 70C water or in the case Ascorbyl Palmitate oil phase of a formula without risk of degradation, and if not, whether they’re OK to add during cooldown at around 40C and if doing so if they need to be added in a special way, e.g. dissolved in RT water or oil first.

  Vitamin B3 (niacinamide)

  Vitamin B5 (pantothenic acid)

  Vitamin B6 (pyridoxine)

  Vitamin B12 (cyanocobalamin)
  Vitamin C (Ascorbyl Palmitate)
  Vitamin D3 (‎Cholecalciferol)

  Thanks!
