Description

Gellan Gum

Gellan Gum is a high-purity anionic polysaccharide produced by microbial fermentation and used in pharmaceutical, food, and biomedical formulations as a gelling, stabilizing, and suspending agent. It is valued for its ability to form clear, firm gels at low use levels and for its excellent thermal and pH stability.
Gellan Gum appears as a white to off-white free-flowing powder that disperses in water and hydrates upon heating. Upon cooling, it forms gels in the presence of monovalent or divalent cations. Its gel strength and texture can be precisely controlled by concentration, ion type, and processing conditions.
In pharmaceutical and related applications, Gellan Gum is used in:
• Oral and topical gel formulations
• Ophthalmic and nasal delivery systems
• Controlled-release and in situ gelling drug delivery platforms
• Suspension stabilization for liquid dosage forms
• Encapsulation matrices and hydrogel systems
• Research involving polysaccharide-based biomaterials
Gellan Gum functions by forming three-dimensional polymer networks that provide structural integrity, clarity, and viscosity control. Its predictable gelation behavior supports reproducible formulation performance across a wide range of applications.
CarboMer supplies Gellan Gum with details of molecular weight distribution, acyl content, purity, moisture level, and microbial quality. The material is suitable for regulated pharmaceutical manufacturing, research, and advanced formulation development.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity (IR), viscosity, gel strength, loss on drying, ash content, and microbial limits. Technical support is available to assist with dispersion techniques, gel optimization, and application-specific formulation needs.
As with all CarboMer supplied polysaccharide excipients, Gellan Gum is supported by dependable global supply, rigorous quality control, and expert technical guidance to ensure consistent and reliable performance across pharmaceutical and biomedical applications.
