  Cetyl Alcohol Crystallization

  Posted by gfeldman on October 22, 2015 at 1:40 pm

  Dear fellow Chemists,

  I am encountering a strange phenomenon (to me at least) where it appears that my cetyl alcohol is recrystallizing over time, could you please offer your advice on how I might remedy this? Oil phase below. Recrystallization appears as small circles of white that form semi-solid pieces over a time span of a month. It is of note that the oil phase is added directly to the water phase, one at a time at 80C.

  4% Cetyl Alcohol
  1.5% Peg-100 Stearate/Glyceryl Stearate
  1% Cap/Cap
  0.5% Dimethicone

  Thank you for any help you provide and I look forward to your feedback!

  Can you substitute Cetearyl for Cetyl?

  I could give it a try. I can imagine how the stearyl alcohol’s presence would inhibit a crystallization matrix. Thanks for the suggestion @Bobzchemist!
