    Hi , 
    If i want to make a Shampoo ( Viscosity ~ 5000 CPS ) How much HEC i need into the formula ? 
    I use 1% of HEC and the viscosity still ~ 1500 CPS .

    @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.
