The concepts of “green chemistry” are gaining importance in the agri-food sector due to the need to minimize pollution from toxic chemicals, improve the safety and sustainability of industrial processes, and provide “clean-labeled products” required by consumers. The application of the cloud point extraction (CPE) is considered a promising alternative to conventional organic solvents. In the CPE, the separation of compounds from the bulk solution occurs by adding a surfactant (either non-ionic or ionic). When the solution is heated to or above a critical temperature, referred to as the cloud point, two phases are formed—micellar and aqueous. Recently, the horizons of the traditional CPE have been increasingly expanding by improved procedures and integration with other techniques, such as the microwave- and ultrasonic-assisted extraction. This article provides an updated overview of the theory and research articles on the CPE from 2018 to 2023 and critically discusses the issues relevant to the potential applicability of the CPE as a promising and green technique for antioxidants recovered from plant materials. Finally, some future perspectives and research needs for improved CPE are presented. Full article
