Ideal and nonideal mixing effects of amino acid based-surfactant on interfacial rheology and foam properties
Surfactants are mainly used as mixtures to obtain the foam properties which are suitable for use and purpose. In this study, it was found that a mixture of glycinate- and glutamate-based surfactants produced a...
