Description

Colanic Acid is a high-molecular-weight bacterial exopolysaccharide known for its unique rheological and film-forming properties. This biopolymer is valued for its ability to modify viscosity, stabilize emulsions, and act as a protective hydrocolloid in demanding formulations. It serves as a critical functional ingredient for industries requiring advanced biomaterials, including pharmaceutical development, cosmetic science, food technology, and biomedical research.

Application

• Pharmaceutical Excipient: Used as a stabilizer, viscosity enhancer, and controlled-release matrix in tablet coatings and hydrogel formulations.
• Cosmetic & Personal Care: Functions as a natural thickener, film-former, and moisturizing agent in serums, creams, and lotions.
• Food Science & Research: Employed as a texture modifier, gelling agent, and stabilizer in experimental food systems and functional food products.
• Biomedical Research: Utilized in cell culture, biofilm studies, and as a scaffold material in tissue engineering applications.
• Industrial Biotechnology: Acts as a bio-based rheology modifier in coatings, adhesives, and other specialty chemical formulations.
