AMPHOSOL® CS-50 E is a cocamidopropyl hydroxysultaine that is compatible with anionic, nonionic, amphoteric, and cationic surfactants and is stable over a wide ph range. It exhibits high foaming even in high electrolyte solutions and is stable in extreme alkaline solutions. This amphoteric surfactant exhibits foam synergies with common anionics and can be used in place of cocamidopropyl betaine to boost flash foam.
