  • Carbopol Gel Hand sensitiser

    Posted by jeff2000 on June 28, 2020 at 10:42 am

    I am trying to make carbopol gel hand sanitizers 
    100 ml of distilled water and 
    1gm of carbopol powder
    keep it for 6 hours for hydration 
    once the gel made I mix 75% IPA to it 
    and then add TEA to neutralise

    the issuer I am facing is

    1- some times it’s makes a perfect viscosity , but some times it’s doest and stay liquid

    2- mire over it’s not 100% clear it’s bit muddy  

    please experts guide me how to come over this situation 

    I am not 100% sure how much TEA to add in 100 ml of water base 

    Thanks

    Can you list your formula as percent? It’s not clear exactly how much you are making. IPA is at 75% concentration w/w?
     You don’t say what kind of carbopol-there are different grades with different levels of clarity and alcohol tolerance.  

    Hand sanitizer made wrong is not effective and in these times it would be a shame to waste the alcohol.

    You’re better off just following the already released formulas for liquid sanitizers or using 75% IPA as is
