How to formulate a properly foaming cationic cleansing conditioner?
I have been trying to formulate properly foaming cleansing conditioners
cationics don’t foam much on their own, so an additional, mild surfactant must be added
So far I have tried:
CAPB and glucosides = they thin out and destabilize emulsion at higher concentrations needed for proper foaming
ethoxylated fatty alcohols = not that mild
anionics = not compatible with BTMS or CETAC cationics
Sodium lauroyl sarcosinate = just ordered it, waiting for it to arrive to try it
Any other ideas?
The basic formulas I have tried are something like
- water q.s. to 100%
- Methylparaben 0.3%
- Propylparaben 0.1%
- BTMS-50 3-5%
- CETAC 0-0.5% active (it improves foam a bit, but also thins out the formulation, unless cetearyl alcohol is added)
- Polyquaternium-7 0-0.5% active
- Cetearyl alcohol 0-4% (it reduces foam a bit, but increases viscosity and seems to improve emulsion stability)
- Silicones (dimethicone, dimethiconol) 0-1% active. Will replace them with Amodimethicone, as they seem to reduce foaming too.
- Synthetic fragrance
- Polyox WSR301 0-0.1%
