The core strengths of alkanolamide surfactants lie in their multifunctionality and formulation synergism: they simultaneously deliver three core functions—foaming, foam stabilization, and thickening—optimizing product systems without requiring additional auxiliaries. When blended with nonionic or anionic surfactants, they exhibit significant synergistic effects, boosting overall cleaning power by over 30%. Additionally, their mild, low-irritation properties make them suitable for sensitive skin care formulations while meeting environmental policy requirements—characteristics difficult for single-function surfactants to replicate.
