Science
Mechanism of Action
As an amphoteric surfactant, Disodium Lauroamphodiacetate reduces surface tension, enabling the effective removal of dirt and oil from skin and hair. Its amphoteric nature allows it to perform as both an acid and a base, with pH-dependent ionic characteristics, forming micelles above its Critical Micelle Concentration. This versatility also makes it an effective foam booster, emulsion stabilizer, and a skin and hair conditioner. Additionally, it possesses hydrotrope properties, enhancing the solubility of poorly water-soluble ingredients within formulations.

Safety
Safety Profile
The CIR Expert Panel concluded that Disodium Lauroamphodiacetate and related fatty amphocarboxylates are safe for use in cosmetic formulations. Regulatory agencies, including the US FDA and EU's Cosmetics Regulation, have approved its use within specified concentration limits, with a reported maximum concentration of 5.4% in leave-on hair preparations. While generally considered mild and non-toxic for most skin types, clinical observations indicated potential for irritation in specific populations, such as atopic or surfactant-sensitive individuals, at concentrations of 1% and 2%.
