  • Emulsion type

    My formula consists of fatty alcohols, few ester oils, ethoxylated fatty alcohol and glyceryl stearate but self-emulsifying grade which has a small percentage of alkali. I call it non-ionic emulsion as I have no neutralization in this recipe. Am I right in calling this emulsion non-ionic????

    the GMS SE is anionic so personally I wouldn’t label the emulsion non-ionic.

    That means any ingredient with a charge in emulsion would render the emulsion anionic or cationic depending on the nature of ingredient.

    I think it would depend on the charges of the other ingredients and their function. You mentioned GMS SE which I know is anionic but would be helpful to know the INCI of the other ingredients.

    Normally GMS SE is paired up with a high HLB emulsifier for o/w (if your emulsion is o/w).

    It is an o/w emulsion, and its a very poor formula as well. It has cetostearyl alcohol, cetyl alcohol, glyceryl stearate SE, mineral oil, isopropyl palmitate, ceteareth-20, colorants, preservative, walnut shells. Do you think it is an anionic emulsion?

    GMS SE, is usually Glyceryl Stearate and Potassium Stearate, so your emulsion will be anionic.  pH should be high too, around 7 to 8 else you’ll just end up with Stearic Acid.

    Thanks for listing the INCI of your other ingredients milliachemist.  I would still say your emulsion is anionic.
