2% NACL +2.4 citric acid salt in shampoo with 3% SLS powder
In shampoo we should add up to 2% salt or NACL. If we use 3% SLS powder in shampoo, it requires around 2.4% citric acid to adjust pH to 5.
Now if we add 2% NACL to this shampoo, does it have 2% salt total or 4.4% salt total?
If 4.4%( 2 from NACL and 2.4 from citric acid) then is it ok to have this amount of salt in a Shampoo to get the desired viscosity?
