MACKAM® C 37 is a high-purity grade of Cocamidopropyl Betaine with a refined alkyl distribution. It remains stable and effective across a broad pH range and is compatible with anionic, cationic, and nonionic surfactants. MACKAM® C 37 features exceptionally low and stable color with minimal residual odor. Compared to MACKAM® 35 and other standard Cocamidopropyl Betaine grades, it offers superior flash foam and viscosity-building properties in anionic-based systems. MACKAM® C 37 is preserved with a combination of benzyl alcohol, benzoic acid, and tetrasodium EDTA.
