Any good options for thickeners in a pH 3.5 glucoside based cleanser? Ideally able to generate a clear or clear ish solution?
Xanthan Gum isn't very stable at that pH, Carbomer is not suitable, Sclerotium Gum isn't clear and leaves a lot to be desired texture wise although it is acid stable, acrylate polymers might hurt TEWL over time according to some research.
Any other options?

Peg-120 Methyl Glucose Dioleate might also be a good choice here. HEC and HPMC hasn't worked well in the past, makes a very granular solution.
