Comparing Decyl-beta-maltoside and Octaethyleneglycol Mono n-Decyl Ether in Mixed Micelles with Dodecyl Benzenesulfonate.
The interactions between polyvinylpyrrolidone (PVP) and a mixture of anionic and nonionic surfactants have been investigated by surface tension measurements. The surfactant mixtures are decyl-beta-maltoside (C(10)M) with dodecyl benzenesulfonate (C(12)BS) and octaethyleneglycol mono n-decyl ether (C(10)EO(8)) with C(12)BS. Surface tension measurements of the surfactant mixtures in the presence of PVP show that C(10)EO(8) competes more effectively than C(10)M with PVP in the interaction with C(12)BS.
