    @karima I’d keep Glycerin to the minimum (not more than 0.5%), since it can potentially reduce the potency of ethanol. Also, use Carbopol 980 instead of 940, since 940 has some traces of benzene.

    @karima The amount of Carbopol depends on how viscous you want your gel to be. For the amount of TEA, you might want to take a look at this info from the manufacturer of Carbopol: https://www.lubrizol.com/-/media/Lubrizol/Health/TDS/TDS-237_Neutralizing_Carbopol_Pemulen_in_Aqueous_Hydroalcoholic_Systems-PH.pdf.
