Conflicts

  • Formulations must rigorously control levels of impurities, particularly 3-dimethylaminopropylamine (DMAPA), to prevent potential sensitization. The CIR Expert Panel emphasizes the necessity of formulating products containing this ingredient to be non-sensitizing.

Safety

Safety Profile

CIR Status
Safe with restrictions
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Isostearamidopropyl Betaine is safe for use in cosmetics, provided the final product is formulated to be non-sensitizing. This restriction primarily addresses the potential for allergic contact dermatitis, which has been associated with impurities such as 3-dimethylaminopropylamine (DMAPA) in related betaines. DMAPA levels in Isostearamidopropyl Betaine have been reported below 0.0002%. While explicit maximum concentrations for Isostearamidopropyl Betaine itself are not detailed, related amidopropyl betaines (e.g., Cocamidopropyl Betaine) have been deemed safe up to 6% in leave-on products and 30% in rinse-off products. Strict control of impurities is paramount for safe application.
