GMS SE is a potassium soap, and functions as a soap, hence why the mfg’s recommend that it be used at higher pH’s. Maybe the rest of the formula can carry it?
If you want something anionic at a low pH, look at SSG.

I guess that gms se contains basically non ionic emulsifier which is glyceryl stearate and very low level of stearate soap the other ingredients are : Ppg15 Stearyl Ether, Isopropyl Myristate, Aluminum chlorohydrate, parfum, Phenoxyethanol, Sodium benzoate.
I already made sample and it looks great: very smooth texture with ordinary viscosity.
So my guess, scientifically even with low pH just the stearate will decompose to stearic acid and base then because the low level of soap in gms se the stability will be fine, not?
