The best way to get the gel by using carbomer is to rub the carbomer well and sift it through a sieve with small holes like flour so that there are no lumps, then sprinkle it on the surface of the water and leave it for 24 hours until saturating. Then, with constant stirring, we start to adjust the acidity of the medium by using alkaline solution such as sodium hydroxide or triethanolamine.
