  • Can Aculyn Excel gel 70% alcohol?

    Posted by Gunther on April 21, 2020 at 2:38 pm

    I’m currently looking for Carbopol Ultrez alternatives as it’s getting harder to find.

    I’m considering Aculyn Excel.
    Has anyone tried it with 70% alcohol?
    So far I haven’t been able to get my hands on it, and it will take a couple weeks before it arrives, so I haven’t been able to experiment with it.

    Yeah Gunther it will, I ran a trial with IPA as well and it came out pretty good and clear. Viscosity is on the lower side compared to carbopols.

    5% Aculyn Excel (as is), yields a very low viscosity gel for both 60 and 70% alcohol test batches.
    Just not thick enough for a sanitizer gel.

    8% Aculyn Excel yields a low viscosity gel (too low for my taste), but the real problem is that it leaves a sticky afterfeel.

    Aculyn 38 and 88 work but viscosity is a bit low. The 88 has a slightly higher viscosity, but they also leave a sticky after feel.

    Gunther they all the same issues more or less. Viscosity on lower side and sticky after feel in certain Aculyns.
