Influence of anionic surfactants on coacervation with cationic guar gum for hair care applications

The findings emphasize that coacervate stability, deposition efficiency and adhesion to hair fibres are optimized when CGG and surfactants are present in balanced ratios. The 0.5% CGG/0.5% surfactant formulation consistently exhibited superior stability, coverage and interaction with damaged hair, reinforcing its potential as an effective conditioning and protective system. These insights provide a foundation for improving coacervate-based hair care formulations, ensuring enhanced performance and long-term benefits.
