Sodium Alginate Analysis Service | Pharmaceutical Excipient

Sodium alginate is a natural polysaccharide extracted from brown algae and is the sodium salt of alginic acid. It is mainly composed of residues of D-mannuronic acid (M) and L-guluronic acid (G). Due to its unique physicochemical properties, sodium alginate is widely applied in pharmaceutical excipients, food, and cosmetics. In the pharmaceutical field, sodium alginate is commonly used as a binder and disintegrant in tablets and capsules, as a thickening and suspending agent in oral liquid formulations, as a stabilizer in emulsions, and as an important carrier in sustained-release formulations and drug delivery systems. It not only improves drug formation and stability but also regulates drug release rate and enhances formulation performance.

With the tightening of global pharmaceutical regulations and increasing quality requirements, the source, structure, purity, viscosity, and impurity control of sodium alginate have drawn increasing attention. As a professional pharmaceutical excipient analysis CRO, MtoZ Biolabs has launched the sodium alginate analysis service based on pharmaceutical excipient, relying on advanced analytical platforms and an experienced team to provide systematic detection and evaluation. This service enables pharmaceutical companies and research institutions to comprehensively assess excipient characteristics and ensure compliance in R&D and regulatory submission.

 

Services at MtoZ Biolabs

MtoZ Biolabs’ sodium alginate analysis service includes chemical, physical, and functional multi-dimensional evaluations, aiming to provide clients with complete quality and performance data support. To achieve this, we provide a range of targeted assessments, including:

✔️ Physicochemical Characterization: Appearance, solubility, pH, moisture content, and viscosity testing to ensure excipients meet pharmacopeial and formulation requirements.

✔️ Molecular Structure and Composition: Analysis of M/G ratio and degree of polymerization to assess the impact of block structure on excipient performance.

✔️ Impurity and Safety Testing: Detection of heavy metals, ash, sulfated ash, microbial limits, and harmful residues to ensure excipient safety.

✔️ Functional Testing: Evaluation of performance as a binder, disintegrant, or thickening agent in tablets and suspensions, simulating formulation scenarios.

✔️ Stability and Storage Performance: Monitoring degradation trends and viscosity changes under different conditions of temperature and humidity to predict storage and application risks.

 

Through these systematic analyses, clients can not only obtain basic parameters of excipients but also understand their adaptability in different formulation systems.
