Amphoteric surfactants


Amphoteric surfactants are surfactants where the charge changes as a function of the pH value of the formulation in which they are used. They are generally regarded a mild surfactants but this is not a simple matter and may not always be true. Amphóteric surfactants build complexes in combination with anionic surfactants and these complexes are milder than the individual surfactants.
