  • Thickener for clear low pH exfoliating cleanser?

    Posted by zink on September 25, 2018 at 3:54 pm

    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?

    Sepimax Zen is a polymer thickener that can be used in extremely low pH formulations. It can be used in surfactant systems too.

    Thanks, which smart line from lubrizol @DAS?

    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.

    @em88 bang on money here, Methocel 40-101 would be a great choice I suppose. Need slight neutralization, and back acid neutralization is much easier without any loss of viscosity. I have based my comments on a trial for hand sanitizer free of water ethanol having CHG. Cellulose are a liitle slimy in application IMO but they can be worked around as well. Did a beard wash with HEC and an APG, worked fine.
