Emulsifyer percentage and emulsion thickness
Hello formulators! Need to clarify my knowlege of emulsification.
Do I understand correctly,that if my product emulsifyes with minimal % of emulsifyers, then I correct the thickness with cetyl alcohol, gums and waxes without increasing emulsifyer percentage? This week I experiment a lot with different emulsifier combinations and oil percentage, to get different textures and minimize soaping effect. My last test is this emulsion and I don’t know if it is ok to leave
Montanov on 1%. Would be grateful for help.
69.4% - Water
1% - Montanov 68
0.3% - Sodium Stearoyl Glutamate
5% - Cetyl Alcohol
0.8% - Carnauba wax
20% - oils and butters
0.2% - Xanthan gum
2% - Glycerin
0.3% - Sodium Phytate
1% - Geogard UltraPH -5

It depends on the Emulsifier, Eugene. Montanov 68 yields low viscosity emulsions, so it will require a higher amount of Fatty Alcohols to achieve a cream viscosity as opposed to a lotion viscosity. Try making the same formula with a different emulsifier and you will see the effect.

Thank you for answer Mark. I love creaminess of Montanov 68, I’m just trying to minimize its percentage because of soaping. For example with Glyceryl Stearate Citrate as a primary emulsifier, I have no soaping, but the emulsion has watery feel on skin, that I didn’t like.
