Abstract
This paper reviews the literature on various biosurfactant mixtures used to obtain foams. The interactions between different biosurfactants, biosurfactants, and synthetic surfactants, biosurfactants' interactions with various additives (as non-surface-active macromolecules or particles), and the impact of pH and ionic strength variations on adsorption processes, foamability, foam stability, and rheology are discussed. Biosurfactants are natural and synthetic compounds that can facilitate the process of foam formation and stabilisation; they are an alternative to classical surfactants. Research on such materials will allow the development of innovative foaming technologies that minimise the negative environmental effects of foaming compounds without losing the properties of the final product.
期刊介绍：
Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications.
Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments.
Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
