Do you still want or need adding Cetrimonium if you already have BTMS-50 in conditioners?
Behentrimonium is almost identical to Cetrimonium, just with a longer carbon chain, that makes it less water soluble.
I DID felt some extra detangling and smoothness from the added Cetrimonium, but so did some extra BTMS-50 as well.Leave-on conditioner formula:
Heated phase:
90% water
0.5% Methylparaben (will later switch to something like 0.4% Methylparaben + 0.1% propylparaben)
1.5% BTMS-50
Cool down phase:
1.5% Dimethicone
0.86% Generic CETAC solution @29% ( 0.25% active CETAC )
1.5% Dehyquart GC 7 BZ (Polyquaternium-7)
citric acid qs to pH 6
water qs to 100%Rinse-off formula

Keep or dump CETAC?
Is adding Guar hydroxypropyltrimonium-Cl likely to help, or be overkill?
Any other suggestions?
