My daughter uses this in preference to my own more complicated formula! Perhaps someone would like to suggest starting percentages? I've given mine.
water (approx. 80%)
cetearyl alcohol (10%?)
stearamidopropyl dimethylamine (2%?)
behentrimonium chloride (2%?)
citric acid (q/s for pH=5)
(the rest is fragrance, preservatives, and marketing ingredients with practically zero% content)
and can I substitute cetrimonium chloride for the behentrimonium chloride?
