Compatibility
Works well with:
Sodium Laureth Sulfate Sodium Lauroyl Sarcosinate Decyl Glucoside Coco Glucoside Glycerin Panthenol Niacinamide Hyaluronic Acid Citric Acid Sodium Chloride
Use caution with:
High-concentration Anionic Surfactants at extreme pH Cationic Surfactants at high levels Strong Oxidizing Agents
Cocamidopropyl Betaine is amphoteric and is broadly compatible with anionic, cationic, and nonionic surfactants, making it a versatile co-surfactant and foam booster. At high pH or with high concentrations of cationic actives, charge interactions can reduce performance or cause precipitation. It is known to cause sensitization in some individuals, historically linked to amidoamine and 3-dimethylaminopropylamine (DMAPA) impurities from manufacturing.
Formulation notes
Considered a mild, skin-compatible surfactant; however, it is a documented sensitizer in some populations due to processing impurities (DMAPA, amidoamine). CIR and EU Cosmetics Regulation permit use in rinse-off and leave-on products; ensure high-purity grade for leave-on applications. Typical rinse-off use is 2–15%, leave-on closer to 1–3%.
