  solubilize vitamin E

  Posted by ltruong on July 25, 2017 at 8:04 pm

  Hi All,
  I am trying to formulate a clear gel below

  glycerin                                   3
  propylene glycol                      2 
  Aloe Vera extract                     2
  isopropyl alcohol                      2
  Menthol                                   0.05
  Vitamin E                                  1
  CMC                                         0.5
  Carbomer                                  0.3  
  TEA                                           0.3
  PEG-40 hydrogenated castor oil  4
  Phenoxyethanol                         0.5
  fragrance                                   0.1
  water                                         q.s

  I tried to incorporate all ingredients first before adding gelling agents. I am struggling to obtain a clear gel for 2 reasons (I did the knockout experiments)
  1. Premixed menthol in isopropyl alcohol caused the turbidity of the solution, I tried to warm solution to 45 and mix well but didn’t work. what happened when menthol+alcohol in water, I think its air but I am not sure? and are there ways that we can incorporate menthol without causing turbidity?
  2. I solubilized Vitamin E in PEG-40 Castor oil before adding to the solution and the solution became turbid. I increased PEG-40 to 8% but didn’t help. Are there any other solubilizer/ emulsifiers that can solubilize Vitamin E?

  thank you for sharing your knowledge !

  Easiest way is use VE phosphate from Shewo Denko.
