| Alginic Acid | Alginic acid is a tasteless, practically odorless, white to yellowish white, fibrous powder. Synonyms: Acidum alginicum; E400; Kelacid; L-gulo-D-mannoglycuronan; polymannuronic acid; Protacid; Satialgine H8. CAS No. 9005-32-7. Product ID: PE-0139. Molecular formula: (C6H8O)n. Mole weight: 20000 ~ 240000. Category: Stabilizing Agents; Suspending Agents; Sustained Release Agents; Tablet Binder; Tablet Dsintegrant; Viscosity-increasing Agents. Product Keywords: Binder Excipients; Stabilizers; Suspending Agents; ; PE-0139; Alginic Acid; Stabilizing Agents; Suspending Agents; Sustained Release Agents; Tablet Binder; Tablet Dsintegrant; Viscosity-increasing Agents; (C6H8O)n; 9005-32-7. UNII: 8C3Z4148WZ. Chemical Name: Alginic acid. Grade: Pharmceutical Excipients. Administration route: Ophthalmic, oral. Dosage Form: Ophthalmic preparations, oral capsules, and tablets. Stability and Storage Conditions: Alginic acid hydrolyzes slowly at warm temperatures producing a material with a lower molecular weight and lower dispersion viscosity.Alginic acid dispersions are susceptible to microbial spoilage on storage, which may result in some depolymerization and hence a decrease in viscosity. Dispersions should therefore be preserved with an antimicrobial preservative such as benzoic acid; potassium sorbate; sodium benzoate; sorbic acid; or paraben. Concentrations of 0.1-0.2% are usually used. Alginic acid dispersions may be sterilize |  |

| Potassium Alginate | Potassium alginate occurs as a white to yellowish, fibrous or granular powder; it is almost odorless and tasteless. Synonyms: Alginic acid, potassium salt; E402; Improved Kelmar; potassium polymannuronate. CAS No. 9005-36-1. Product ID: PE-0563. Molecular formula: (C6H7O6K)n. Category: Emulsifying Agents; Stabilizing Agents; Suspending Agents; Thickening Agents. Product Keywords: Stabilizers; Emulsifier Excipients; Suspending Agents; ; PE-0563; Potassium Alginate; Emulsifying Agents; Stabilizing Agents; Suspending Agents; Thickening Agents; (C6H7O6K)n; 9005-36-1. UNII: 44ZPJ5W2J1. Chemical Name: Potassium alginate. Grade: Pharmceutical Excipients. Stability and Storage Conditions: In the solid state, potassium alginate is a stable material that is not prone to microbial spoilage. Over time, a slow reduction in the degree of polymerization can occur, which may be reflected in a reduction in the viscosity of solutions. As both temperature and moisture can impair the performance of potassium alginate, storage below 25°C is recommended. Potassium alginate solutions are stable at pH 4-10; long-term storage outside this range can result in depolymerization of the polymer through hydrolysis. Gelation or precipitation of the alginate can occur at pH values less than 4. Liquid or semisolid alginate formulations should be preserved: suitable preservatives are sodium benzoate, potassium sorbate, or parabens. Potassium algin | |
