Expert Verdict

Like all amidopropyl betaines, potential contamination with DMAPA (3-dimethylaminopropylamine) and amidoamine - both known contact sensitizers. The ingredient itself is not the primary allergen; impurities are.. Amphoteric surfactant with excellent mildness and foam-boosting. The isostearyl chain provides enhanced conditioning compared to cocamidopropyl betaine. Compatible with anionic, cationic, and nonionic surfactants.
