Description

Sodium Algin Sulfate is a water-soluble, sulfated polysaccharide derivative of alginic acid, a natural polymer extracted from brown seaweed. This modified alginate offers enhanced stability and unique rheological properties compared to its non-sulfated counterpart, making it valuable for specialized industrial and biomedical applications. Key industries that utilize this compound include pharmaceuticals, cosmetics, and advanced material science, where it serves as a functional thickener, stabilizer, and bioactive agent.

Application

• Pharmaceutical Excipient: Used as a stabilizer, viscosity modifier, and controlled-release matrix in tablet coatings and gel formulations.
• Cosmetic & Personal Care: Functions as a high-performance gelling agent, thickener, and film-former in creams, lotions, and hair care products.
• Biomedical Research: Employed in cell culture and tissue engineering scaffolds due to its biocompatibility and structural similarity to natural glycosaminoglycans.
• Food Industry (where approved): Acts as a texturizing and emulsifying agent in specialized food products.
• Industrial Applications: Serves as a binder, thickener, or sizing agent in paper, textile, and ceramic manufacturing processes.
• Laboratory Reagent: Used in biochemical research and analytical chemistry for its ion-exchange and complexation properties.

Quality Control

Our Sodium Algin Sulfate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as sulfate content, viscosity, and heavy metal limits are available upon request. We can tailor quality standards to meet specific customer requirements, including compliance with relevant guidelines for pharmaceutical or cosmetic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect the product's physical properties and stability.
