Abstract:

The mixtures of alkyl polyglycoside (APG) and alkyl polyglycoside sulfosuccinate (APG-SS) with different mixing ratios were studied by measuring their surface activity and foaming properties. The phase behavior of the ternary system of APG/APG-SS/H2O was also studied. The results show that the best synergism is found in surface activity (γcmc=27.90 mN/m, cmc=0.044 mmol/L, Γmax=10.86 μmol/m 2, Amin=0.15 nm 2) when nAPG-SSnAPG=2∶8. The mixed system has higher foaming ability in distilled water and hard water than single surfactant when nAPG-SSnAPG=2∶8 and 4∶6, so it has synergism. At the same time, the foam stability of the mixed system is better than APG, which can improve the hard water resistance of APG. The phase diagrams of the APG-SS/APG/H2O ternary systems were characterized by micellar phase, a region where lamellar liquid crystal and micellar phases coexisted and a region of “aqueous two-phase”.
