# Gelifying hydrogen peroxide

What substances could be used to gelify 60% hydrogen peroxide? I imagine anything organic like agar would be broken down by the radicals. I tried looking up what dentists use and the only thing that came up was glycerine, which I know from experience doesn't make gels with water, so I doubt it would work with $$\ce{H2O2}.$$

• Dentists use what they call carbamide peroxide to avoid premature decomposition of the gel itself. – andselisk Sep 29 '19 at 3:27
• Since 60% H2O2 decomposition is highly exothermic and produces reactive oxygen rather violently, I'd question adding anything that might catalyze that reaction. – DrMoishe Pippik Oct 3 '19 at 18:34
