    I wrote the steps above. We registered a product with 70% m/m ethanol already.
    Maybe you are looking for high viscosity gels? For me 6000-10000 cP is enough for a hand sanitizer. 

    Hello, can you say how much triethanolamine do you use?

     I am using 0.35% carbopol 940.

    When I add 0.17% triethanolamine, in the last half, it forms a milky mixture and it losses all viscosity.

    I am concerned that this happens because I only have 20% m/m of water.

    @EVchem and @RawMaterialGirl thank you for your input.
    In my company we don’t do color cosmetics, only skincare so the color is not so crucial as is color cosmetics.
    I am looking at simpler catalogs (fewer colors than Pantone) and they do indicate validity.
