In this paper. Cationic guar gum (CGG) with perfect transparency was obtained by hydroxypropyl purification and then cationization modification on guar gum. The chemical structure of CGG was characterized by1R. The contrast among guar gum hydroxypropyl guar gum and Cationic guar gum was analyzed by TG and DSC. Meanwhile, Compatibility effect on Cationic guar gum. Anionic surfactant. Amphoteric surfactant and Anionic surfactant was studied. Its compatibility program was analysed according to luminousness.
