I am developing a new formula of shampoo using large amount of surfactants like Sodium Laureth Sulfate, Disodium Laureth Sulfosuccinate, Cocamidopropyl Betaine and I am facing a problem that too much foam created during the mixing process. I tried heating but it seems not to be improved much.
How to reduce foaming during mixing? And I also use Sodium benzoate as the preservative and citric acid to adjust the pH. Do them play any role toward reducing foaming?
