Carbopol Gel Hand sensitiser

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
