Marine‐derived surface active agents: Health‐ promoting properties and blue biotechnology‐based applications

Abstract

Surface active agents are characterized for their capacity to adsorb to fluid and solid‐water interfaces. They can be classified as surfactants and emulsifiers based on their molecular weight (MW) and properties. Over the years, the chemical surfactant industry has been rapidly increasing to meet consumer demands. Consequently, such a boost has led to the search for more sustainable and biodegradable alternatives, as chemical surfactants are non‐biodegradable, thus causing an adverse effect on the environment. To these ends, many microbial and/or marine‐derived molecules have been shown to possess various biological properties that could allow manufacturers to make additional health‐promoting claims for their products. Our aim, in this review article, is to provide up to date information of critical health‐promoting properties of these molecules and their use in blue‐based biotechnology (i.e., biotechnology using aquatic organisms) with a focus on food, cosmetic and pharmaceutical/biomedical applications.
