Science
Mechanism of Action
This amphoteric surfactant functions by effectively lowering the surface tension between water and oily substances, enabling the thorough removal of dirt and sebum. Its unique amphoteric nature allows it to exhibit both anionic and cationic properties depending on the pH, facilitating versatile cleansing without stripping the skin of its vital lipids. Additionally, it helps to stabilize foam and can contribute to the viscosity of a formulation.

Amphoteric surfactants, including related amphodiacetates, demonstrate robust stability across a wide pH range, showing good resistance to both acidic and alkaline conditions. They maintain performance and solubility effectively even in hard water environments.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has evaluated structurally similar 'Fatty Amphocarboxylates,' concluding they are safe for cosmetic use under current practices and concentrations, provided they are formulated to be non-sensitizing. While Disodium Isostearoamphodiacetate itself was not explicitly listed, its structural resemblance suggests a comparable safety profile. No specific FDA status or SCCS opinion was found for this ingredient.
