Disodium cocoamphodiacetate is the diacetate member of that family, built on the fatty acids of coconut oil.\u003C\u002Fp>\u003Cp>It is rarely the cleaning agent. Its job is to be the second surfactant in the bottle — to thicken, to turn coarse foam into a fine dense lather, and to reduce how harshly the primary surfactant treats the skin surface. The accepted explanation for that last effect is mixing: the two form combined micelles that hold their molecules more tightly, leaving fewer free surfactant molecules available to interact with skin protein.\u003C\u002Fp>\u003Ch2>The evidence\u003C\u002Fh2>\u003Cp>The mildness of amphoteric-containing blends is well established in formulation work, and the effect is on the system rather than on the skin. Adding one does not repair anything; it makes the cleanser take less. That is worth stating plainly, because \"gentle surfactant\" reads as a benefit when it is really the absence of a harm.\u003C\u002Fp>\u003Cp>One thing this page deliberately declines to do is import a neighbour's record. Cocamidopropyl betaine, the amphoteric most people have heard of, is a recognised if uncommon contact allergen. It is a different chemistry, its allergy history is evidence about itself, and repeating it here as though it transferred would be a guess dressed as a caution.
