surfactant zwitterionique

Zwitterionic surfactants are amphiphilic molecules, meaning they contain both hydrophilic and hydrophobic components. These surfactants are characterized by having both a positive and negative charge on the same molecule, meaning they are electrically neutral. Zwitterionic surfactants are often used in detergents and shampoos due to their mildness and excellent foaming properties. They are also used in pharmaceuticals, food processing, and oil recovery applications. Zwitterionic surfactants have been found to be biodegradable, non-toxic, and non-irritant, making them a desirable alternative in many applications.
