Description

Carrageenan NF

Carrageenan NF is a high-purity sulfated polysaccharide derived from red seaweed and used in pharmaceutical formulations as a gelling, thickening, stabilizing, and suspending agent. Compliant with National Formulary (NF) standards, it is valued for its ability to form thermoreversible gels and to modify viscosity across a wide range of aqueous systems.
Carrageenan NF appears as a white to off-white free-flowing powder that disperses in water and hydrates upon heating. Depending on the specific fraction and ionic environment, it can form elastic or brittle gels and interact synergistically with proteins and other polysaccharides.
In pharmaceutical and related applications, Carrageenan NF is used in:
• Oral and topical gel formulations
• Suspension stabilization in liquid dosage forms
• Controlled-release and matrix-based delivery systems
• Viscosity modification in syrups and solutions
• Encapsulation and hydrogel systems
• Research involving polysaccharide-based excipients and biomaterials
Carrageenan NF functions by forming three-dimensional polymer networks through ionic interactions, particularly in the presence of potassium or calcium ions. This behavior allows precise control over gel strength, texture, and stability in pharmaceutical formulations.
CarboMer supplies Carrageenan NF with defined molecular characteristics, sulfate content, and physicochemical properties suitable for regulated pharmaceutical manufacturing and research applications.
The material is packaged in sealed, moisture-resistant, tamper-evident containers to preserve integrity and performance. 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, viscosity, gel strength, loss on drying, ash content, and microbial limits. Technical support is available to assist with dispersion methods, gel optimization, and formulation development.
As with all CarboMer supplied polysaccharide excipients, Carrageenan NF is supported by dependable global supply, rigorous quality systems, and expert technical guidance to ensure consistent and reliable performance across pharmaceutical and research applications.
