@Muhammad7 you can increase the level of HEC to have more viscosity , change the type of HEC ( there are a lot type of HEC wich give different viscosity ) and finally you can think about other electrolyte resistant thickner .

The problem with just bunging in more of that type of thickener is that you’ll end up with pseudo-plastic consistency. It’s not possible to help without knowing what the formula is.

@em88

Get a sample of natrosol 250 hhx, you will have to add less than 1%
You can check here the difference: https://www.ashland.com/file_source/Ashland/links/PHA18-101_Natrosol_250_HEC_Formulating_elegant_liquid_and_semisolid_%20drug_products.pdf
Pay close attention to the grade you are using. You can go for 2% with your grade.
