FAQ

What is Sodium Alginate (CAS: 9005-38-3)?

Sodium alginate (CAS: 9005-38-3) is a natural polysaccharide derived from brown seaweed. It functions as a gelling agent, thickener, and stabilizer due to its ability to form viscous solutions in water. Its chemical formula is C6H10Na2O9, and it exhibits biodegradability, non-toxicity, and biocompatibility. Sodium alginate is widely used in various industries for its unique properties, including emulsification and film-forming capabilities.

What are the main uses of Sodium Alginate (CAS: 9005-38-3)?

Sodium alginate (CAS: 9005-38-3) is extensively used in food as a thickener, stabilizer, and texturizer. In pharmaceuticals, it serves as a controlled-release agent and binder. Industrially, it acts as a paper sizing agent and in textile processing. Additionally, it is employed in research for drug delivery systems and as a biocompatible material. Its versatility makes it a key component in multiple applications.

Is Sodium Alginate (CAS: 9005-38-3) safe?

Sodium alginate (CAS: 9005-38-3) is generally recognized as safe (GRAS) by regulatory agencies like the FDA and EFSA. It has low toxicity and is biocompatible, making it suitable for food and pharmaceutical use. However, proper handling is advised to avoid inhalation or eye contact. Safety data sheets (SDS) recommend protective measures such as gloves and goggles during industrial applications.

How should Sodium Alginate (CAS: 9005-38-3) be stored?

Sodium alginate (CAS: 9005-38-3) should be stored in a cool, dry place away from direct light. Maintain temperature below 25°C and humidity under 60% to ensure stability. Use airtight containers to prevent moisture absorption and contamination. Avoid exposure to strong acids or alkalis to preserve its functional properties. Proper storage extends shelf life and maintains quality.
