Review my leave in hair spray formula


this is my formula for a leave in hair spray for dry curly hair. I hav used it and liked it, but i wonder if anyone can suggest if I need to bring down the % of ingredients for the silicones. I think I may be using too much considering I also use silicones in my deep conditioner. Any suggestions? I was thinking amodimethicone could be effective at a rate of .5% instead and I could also reduce or eleminate CETAC-30 since it will already be some in the amodimethicone. any thoughts? 

Btms-50 2%
glycerin 4%
Fractionated coconut oil 2%
amodimethicone 1%
cyclomethicone 2%
dimethicone 2%
CETAC-30  2%
liquid germall plus .5%
fragrance .5%
water q.s


  • I was also thinking I could just drop the cyclomethicone and dimethicone and keep amodimethicone at the same usage. 
  • cyclomethicone? If that's D4 or D5, you should review the latest restrictions on use.

  • its d5. I didn't know there were any major restrictions on its use. I'll check it out
  • You can substitute water with flaxseed gel if its for personal use to get some hold. I'm protein sensitive but you can try them if you do not have problems.

    Drop the cyclomethicone and cut or drop the CETAC, since you allude to the fact you are using an analog to DC-949 amodimethicone emulsion (w/CETAC, Trideceth-7) you can just increase that emulsion for better effect.  What MW of dimethicone is there?  200CST works best in that format. Otherwise, not bad!

  • @Perry I saw that about CETAC. mine is at a concentration of 30% active ingredients. Does that mean I can only use .25%  of CETAC 30% active? Or does that mean I can have a total of .25% active CETAC in my leave in as a whole?
  • @chemicalmatt I'm using dimethicone 350 since thats all that I had. I think you have a good point about just using more amodimethicone. you think increasing to 2%  would be enough? 

    I had a feeling to drop the cyclomethicone as well. seemed a bit unneccessary when I review the formula. good point about the CETAC. thanks!

    The limitation is in terms of % active ingredient.  So if the limit is 0.25% in your formula and you have a 30% solution, the max you could use of your solution is about 0.8%
  • @Perry THANKS! makes so much sense to me now
