Bacterial Polysaccharides: Cosmetic Applications

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


Bacterial polysaccharides are extensively used in cosmetic products, especially given their diverse properties and functionalities, assuming an important role in the RandD of new formulations and applications. In this chapter, the principal properties of the main polysaccharides present in this area are described and summarized. Advancements in skin biology knowledge, and the study of new formulations, support the research of active ingredients related to the maintenance of skin integrity and barrier function. Bacterial polysaccharides possess several properties (such as biocompatibility, biodegradability, film-forming, gelling, and thickening) that can provide protective effects on the skin, improving the efficacy of formulations while maintaining the skin in good conditions. Additionally, polysaccharides, which can be processed in emulsions, hydrogels, suspensions, and encapsulating structures, have been demonstrated to enhance the stability of formulations and promote sensorial properties. Data from several clinical studies revealed that the polysaccharide-based formulations promote skin health, with applications in several skin disorder treatments.
