    So, I was  working on Potassium cocoate to make an organic shampoo. The formula would contain: 

    40% Potassium cocoate
    0.3% of preservative
    0.2% of EDTA
    1.8% of Sodium Chloride
    My problem is that the resulting solution is NOT that viscous enough even though I have added Sodium Chloride in it. Should I add more Sodium Chloride? Or should I just change the whole formula? Any thoughts?

    Even simpler, test your pH first, especially with shampoos when thickening is an issue. I get about 5 “emergency” calls a year…”My shampoo isn’t thickening.” I ask “What is the pH?” Half an hour later I usually hear “Never mind, it’s fixed.”

    @miko do u think NaCl can affect the viscosity of shampoo with natural surfactant( without any anion)? I dont think so.

    @miko Think you should try to achieve the optimum pH (read recommended) to gain the viscosity if your electrolyte has failed to live upto the expectations and as pointed out by tonyh. As I have read in some literature of this soap, it needs a working pH of 8-9 for optimum efficacy and for clear formulas. Maybe this piece of info can be useful to you.
