Alginic Acid Analysis Service | Pharmaceutical Excipient

Alginic acid is a natural polysaccharide derived from brown algae and is a linear polymer composed of D-mannuronic acid and L-guluronic acid residues. Due to its unique physicochemical properties, including high water absorption, gel formation, and thickening ability, alginic acid has been widely applied in the pharmaceutical industry. As a pharmaceutical excipient, it can be used as a binder and disintegrant in tablets and capsules, as a stabilizer and thickening agent in emulsions, suspensions, and gels, and it is also utilized in controlled-release systems and drug delivery research. With increasingly strict pharmaceutical quality regulations, higher requirements are being placed on the source, structure, purity, and safety of alginic acid.

Services at MtoZ Biolabs

MtoZ Biolabs’ alginic acid analysis service covers physicochemical characterization, impurity control, quality evaluation, and functional testing, aiming to help clients comprehensively understand excipient properties and ensure stability and suitability in pharmaceutical formulations.

To achieve this, we provide a range of targeted assessments, including:

✔️ Chemical Composition and Structural Characterization: Analysis of the ratio of mannuronic acid to guluronic acid, molecular weight distribution, and degree of polymerization, with evaluation of potential degradation or structural changes.

✔️ Physicochemical Property Testing: Swelling, solubility, viscosity measurement, hygroscopicity, and crosslinking evaluation to assess performance in different formulations.

✔️ Impurity and Safety Analysis: Detection of ash, heavy metals, arsenic, lead, microbial limits, and other potential contaminants to ensure compliance with pharmacopeial and international standards.

✔️ Stability and Storage Performance: Accelerated degradation and stability tests under various temperature and humidity conditions to assess reliability during storage and use.

✔️ Functional Testing: Evaluation of performance as a binder, disintegrant, or sustained-release matrix through simulated formulation studies.

  

Analysis Workflow

1. Sample Receipt and Preparation: Registration and labeling, followed by drying, grinding, or dissolution if needed.

2. Physicochemical Analysis: Measurement of molecular weight, composition ratio, viscosity, and swelling properties.

3. Impurity and Safety Testing: Assessment of heavy metals, microbial limits, and ash content.

4. Functional and Stability Testing: Simulation experiments based on formulation requirements.

5. Data Integration and Report Preparation: Compilation of results into a detailed report with conclusions and recommendations.
