Sedal formula

BelassiBelassi Member, PCF student
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%?)
dimethicone (2%?)
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?

    Behentrimonium chloride (C22) has much better conditioning properties than cetrimonium chloride (C16).

    I'd start with 5% cetearyl alcohol rather than 10, unless it's incredibly thick

    behentrimonium chloride has a higher melting point than cetrimonium chloride, and it forms more stable emulsions

    These ingredients are difficult to find here. Except for the cetearyl of course. I have cetrimonium but behentrimonium is only obtainable from Unobtanium Ltd. And the Shercine S, that's a Lubrizol product but I can't find it anywhere.
