Coco betaine (CB) is often confused with cocamidopropyl betaine (CAPB), but they are not the same. Although they have comparable chemical structures and active content, CAPB’s long name is sometimes mistakenly shortened to “coco betaine,” which is inaccurate.
Coco betaine is a versatile amphoteric surfactant commonly used in cosmetic formulations. It is typically employed as a secondary surfactant in hair and skin cleansing products such as shampoos, bubble baths, shower gels, and facial cleansers. This component works well with anionic, cationic, and nonionic surfactants, and performs reliably even in hard water conditions. It generally outperforms cocamidopropyl betaine in both foaming and viscosity-building, making it an excellent choice for creating richer, more stable formulations.
When combined with anionic surfactants, coco betaine enhances performance through synergistic effects, contributing to increased foam production and improved viscosity. It is also known for its gentle nature, making it well-suited for products that come into contact with the skin. The material is well-suited for use in acidic formulations, making it an ideal option for cleansers containing alpha or beta hydroxy acids (AHA/BHA), as well as for products preserved with organic acids.
Coco betaine exhibits a synergistic effect when combined with sodium cocoyl isethionate (SCI), resulting in a formulation that is milder than either ingredient used alone. This blend is especially effective in high-foaming, sulfate-free formulations.
