Effects of Polypropylene Glycol at Very Low Concentrations on Rheological Properties at the Air–Water Interface and Foam Stability of Sodium Bis(2-ethylhexyl)sulfosuccinate Aqueous Solutions

“…Although the consumption of surfactants needs to be reduced in an attempt to protect ecosystems, decreases in surfactant concentrations have a direct impact on foam stability. Therefore, approaches to achieve high performance with small quantities of surfactant, including the introduction of additives into surfactant solutions to enhance surface-active properties, have been investigated. − In many cases, additives are proteins and synthetic polymers, such as bovine serum albumin and polyvinyl­pyrrolidone, respectively. − Electrostatic and hydrophobic interactions between surfactants and additives have been shown to improve interfacial rheological properties, thereby enhancing foam stability. From the viewpoint of environmental impact, green surfactants and green polymers have also been attracting attention in recent years …”
