    You need to provide more details about your formulation/product and how you are preparing it.

    thanks

    My formula is 

    Deionized Water as a Base liquid
    Carbomer 940 as a Thickener
    Glycerine as a Humectant
    Ethanol as a Biocide
    TEA as a Neutralizer

     - - and your method of preparation is?

    Note that Carbopol 941 has better flow characteristics in a product such as this.

    Better to:
    a) mix the ethanol and water and allow the gases to disperse (the gases are simply air that has been dissolved in the water - these dissolved gases may be the cause of your cloudiness).
    b) mix the Carbopol with glycerin then add most of the premixed ethanol & water.
    c) add the TEA mixed with the remaining ethanol/water mix to the main bulk and mix until homogeneous. Avoid entrapment of air.

     And you must use distilled water or deminarlized water to avoid cloudiness

    Change the quantity of Carbomer if the viscosity does not meet your requirements.

    Swap the TEA for AMP and you should get a nice clear gel

    Based on your questions, you do not have enough experience in this area. I’d strongly recommend doing the sanitizer exactly as WHO mentions if you really must do it yourself.

    Any idea what your Transparency percent is at 8200 cp or somewhere close with the 980? Also, what meter do you use to test that? I use a different carbomer, and mine does not clear up well, so I’m looking at different options. I also use TEA as it is readily available to me. (I do not have access to AMP)

    You can use TEA but you will need more than the AMP. Put enough to get the required ph.

    If you’re following the WHO guidelines, they clearly state that no thickener, or other ingredients must be added.

    You can make sanitizer gel if you want, but it won’t follow the WHO guidelines.

    I have some experiance on water based paint
    we already use a lot of different pH adjuster
    for example AMP90 and 95–Advantex—Superperse 95–KTPP—Falamine Plus—Disamtex amine grades—Silres BS 168 silicone pH adjuster—Vantex T— Lorama Amines
    I know some of them better than Amp grades
    Maybe you can solve your problem with this grades
