Sulfobetaine 12 is widely used as a surfactant in personal care products due to its mildness and compatibility with skin and hair. It is commonly found in shampoos, body washes, and facial cleansers, where it helps to create a rich lather while maintaining moisture and reducing irritation. In the field of biochemistry, it is employed as a zwitterionic detergent for solubilizing membrane proteins without denaturing them, making it valuable for protein purification and analysis. Additionally, it is utilized in industrial cleaning formulations for its ability to stabilize emulsions and enhance the removal of oils and greases. Its unique properties also make it suitable for use in formulations requiring stability over a wide pH range.
