Disodium Lauroamphodiacetate
What is Disodium Lauroamphodiacetate?
Disodium lauroamphodiacetate is a synthetic amphoteric surfactant, formed as the disodium salt from lauric acid—a coconut-derived fatty acid—and diacetic acid derivatives. It carries both positive and negative charges, allowing pH-dependent behavior that makes it exceptionally mild. Primarily used in rinse-off personal care products like shampoos, body washes, and facial cleansers, it functions by reducing surface tension to lift dirt and oils into micelles for easy rinsing. Its dual-charge structure enables foaming, emulsification of oils, and light conditioning effects on hair and skin, while also acting as a hydrotrope to solubilize other ingredients. This versatility supports clear, stable formulations, especially in gentle, low-irritation systems such as baby products.
