If we use Stearamidopropyl Dimethylamine, setearyl alcohol and Amodimethicone emulsion in a leave in spray hair conditioner, what percentage of these ingredients should we use?
For leave in conditioner, is SPDMA, setearyl alcohol and Amodimethicone a good combination?
What would you change, add or remove to improve it's performance?
Other ingredients would we water, preservative and 0.05% fragrance or even fragrance free.
Final pH would be 3.
