The evidence, graded
expert consensusUS safety reviewers (2026) assessed 11 fatty amphocarboxylates, disodium cocoamphodiacetate among them, used to cleanse and foam and most also to condition hair. Doctors have reported allergic rashes, confirmed by patch tests, from products holding related ones. Leftover amine impurities may add to allergy risk and can form nitrosamines. They judged all 11 safe as used in products made not to cause allergy and kept away from ingredients that form nitrosamines; airbrush use had too little data.Ferguson 2026 · Cosmetic Ingredient Review ↗
