Question about Vitamin E solubility

edited December 2018 in General
Hello, How much polysorbate 80 is need for dissolving 0.1% tocophryl in 100 gr water?

Comments

  • :) found it
  • First add tween 80 to vit E in same amount then add to water phase
  • Interesting.  For fragrances you typically need a 4:1 ratio of polysorbate to fragrance. But a vitamin is clearly different. 
  • Two questions: 1)have you tried it yourself 2) Is the liquid transparent or cloudy? I tried to incorporate 1% of tocopheryl acetate to a serum. It took 4:1 of PEG-40 HCO (which is much better solubilizer than poly 80) to achieve  clear liquid 
  • There is no set ratio that you can plug into a Formula and automatically get the proper solubilization. You need to determine this empirically in the Lab.

    I thought vitamin E was notoriously 'difficult' to solubilize to a clear dispersion, i.e. needs considerably more solubilizer than the same amount.

    PEG-40 HCO (which is much better solubilizer than poly 80
    I think it depends on what substance you're solubilizing, whether poly 80 is better or worse than another.
  • Currently water soluble form of Vitamin E available, fresh formulator have to use that one only.
