Product type
Alginic acid is a natural polysaccharide derived from brown seaweed, primarily composed of mannuronic and guluronic acid units. It is commonly used in the pharmaceutical industry as a disintegrant in tablet formulations, helping to facilitate the breakdown of tablets in gastrointestinal fluids. Its gel-forming properties also contribute to its use as a thickening agent and stabilizer in various formulations.
| Chemical formula | C6H8O6 |
| Solubility | Soluble in water; insoluble in organic solvents |
| Molecular weight | Approximately 216.14 g/mol |
| Viscosity | Varies based on concentration and formulation |
| Source | Extracted from brown algae, such as Laminaria and Macrocystis |
When selecting alginic acid, buyers should consider the source and purity of the material, as these factors can influence functionality in formulations. It is important to specify the desired viscosity and particle size, as well as any necessary certifications for pharmaceutical use. Quantities may vary based on production needs, so clear communication about expected usage is essential when requesting a quote.
