Solubilizing a fragrance into dimethicone hair serum

please advise on how to solubilise a fragrance into a silicone. I have not done much research but it's my fifth trial of adding different percentages of PEG-40 Hydrogenated castor oil with a fragrance first then adding the dimethicone or cyclomethicone but failed, it turns turbid and i need it to be crystal clear. thank you so much.


  • Ask your supplier to provide you Silicone compatible fragrances, PEG-40 Hydrogenated Castor Oil won't do the trick here. How much fragrance you are trying to add?? In my experience we never went beyond 0.3% in most of the formulas and we had to be careful with our fragrance choice.
  • procetyl aws at 1.5:! ratio with fragrance may work.
  • @DRBOB@VERDIENT.BIZ procetyl aws is a water soluble surfactant. If there is no water in the formula, i think plain fragrance+silicone can provide the clear finished product you desire @biochemist101. I agree with @Chemist77, you should add fragrance in small increments to see up to what level the clarity can hold up.
