Description

Cyanogum 41 is a high-purity, synthetic polymer widely utilized as a gelling agent and thickener in advanced formulations. Its primary value lies in its ability to form stable, clear gels in aqueous systems, which is critical for achieving precise rheological control. This product is essential for manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking reliable performance in sensitive applications such as electrophoresis media and topical gels.

Application

• As a key gelling agent in the preparation of polyacrylamide gels for biochemical and molecular biology electrophoresis.
• As a thickening and stabilizing agent in the formulation of cosmetic and personal care products, including creams, lotions, and gels.
• In the development of pharmaceutical topical formulations and controlled-release drug delivery systems.
• As a component in the manufacture of specialty adhesives and sealants requiring specific viscosity profiles.
• For use in analytical chemistry as a medium for chromatographic separations and other laboratory techniques.
• In the production of contact lenses and other hydrogel-based medical devices.

Quality Control

Our Cyanogum 41 is produced under a stringent quality management system to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous analytical testing, including assessment of purity, viscosity, and residual monomer content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect the product's performance. Keep away from incompatible materials.
