Guar Gum Analysis Service | Pharmaceutical Excipient

The Guar Gum Analysis Service focuses on systematic testing and comprehensive quality evaluation of guar gum as a pharmaceutical excipient. Guar gum is a natural polysaccharide extracted from guar seeds, primarily composed of galactomannan. Its molecular backbone consists of D-mannopyranose units linked via β-1,4 bonds, with branches of D-galactopyranose connected by α-1,6 bonds, maintaining an approximate mannose-to-galactose ratio of 2:1. This unique structure imparts strong hydrophilicity, thickening ability, and film-forming capacity, making guar gum widely applied in pharmaceutical formulations as a binder, disintegrant, suspension stabilizer, and controlled-release matrix. In addition, guar gum also serves as a thickener in the food and cosmetics industries, and as an eco-friendly additive in papermaking.

Sample Submission Suggestions

To ensure reliable and consistent testing results, we recommend the following for sample submission:

Sample Type: Powdered guar gum, minimum 10 g.

Storage Conditions: Store at room temperature in a dry, light-protected environment to prevent moisture absorption.

Transport: Use sealed packaging to avoid contamination and water uptake.

Additional Information: Provide sample source, batch number, and testing objectives to facilitate the design of an appropriate analytical plan.
