Cosmetics are complex multiphase systems that include different components with distinct functions on the final product. Bacterial polysaccharides are biocompatible, biodegradable, and usually nontoxic natural biopolymers that possess physicochemical properties suitable for use as cosmetic ingredients. Some of them, namely, hyaluronic acid (HA), bacterial cellulose (BC), and levan, have biological properties (e.g., skin regeneration and protection) and are used as active agents in cosmetic formulations. Other bacterial polysaccharides, such as xanthan gum and gellan gum, are mostly used as viscosity controllers and psychosensorial agents and are applied in cosmetic vehicles (e.g., emulsions, gels, and suspensions). The nontoxic nature of these bacterial polysaccharides has been thoroughly assessed by innumerous studies and their safety as cosmetic ingredients has been established.
