Chitin products like Sea-Klear can prevent or eliminate foaming from occurring. Potassium-based alkali soaps are more water soluble and make a softer soap (Example: liquid castile soaps). But its not impossible to find liquid soaps with similarly clean formulations. The effects of water activity and pH can be combined through hurdle technology to control microorganisms more effectively. Helping you get the ingredients just right so you can manufacture world-leading products.
