Sclerotium gum is a natural polysaccharide obtained through the fermentation of the microorganism Sclerotium rolfsii (S. rolfsii), a filamentous fungus. Initially isolated from rotten red peppers as a phytopathogen, S. rolfsii became the most prolific strain in the production of exopolysaccharides (EPSs).1
This biotechnology-derived beta glucan EPS is nonionic and hydrosoluble with gelling, stabilizing and hydrating properties, making it a popular ingredient for various applications.2 With widely used and traditional polymers being petroleum-derived and non-biodegradable, sclerotium gum can act as an eco-friendly and sustainable alternative to conventional polymers in cosmetic formulations.2
