Description

Poly-L-Aspartic Acid, Sodium Salt

Poly-L-Aspartic Acid, Sodium salt is a high-purity, water-soluble polypeptide polymer used in pharmaceutical, biomedical, and industrial applications for its chelating, dispersing, and biodegradable properties. As the sodium salt of a synthetic polypeptide composed of L-aspartic acid residues, it is biocompatible, biodegradable, and highly effective in controlled-release systems, tissue engineering scaffolds, and metal ion sequestration. Poly-L-Aspartic Acid, Sodium salt

• Is a water-soluble, anionic polypeptide polymer with chelating and dispersing capabilities
• Is used in drug delivery systems, tissue scaffolds, and stabilization of metal ions
• Supports controlled release, bioadhesion, and biocompatible formulations
• Is compatible with aqueous systems, hydrogels, and polymer blends
• Is manufactured under Good Manufacturing Practice (GMP) conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly-L-Aspartic Acid, Sodium salt is synthesized via polymerization of L-Aspartic acid monomers followed by neutralization with Sodium hydroxide. Its polyanionic structure allows strong interaction with cationic molecules, enhancing solubility, stability, and bioavailability in formulations.

In pharmaceutical and biomedical applications, Poly-L-Aspartic Acid, Sodium salt is used in:

• Controlled-release oral and injectable dosage forms for small molecules and peptides
• Hydrogels and scaffolds in tissue engineering and regenerative medicine
• Chelation of metal ions in formulations containing divalent and trivalent cations
• Ophthalmic and topical formulations for stabilization and bioadhesion
• Nutraceutical and cosmetic formulations for moisture retention and active delivery

The polymer demonstrates excellent biocompatibility, low cytotoxicity, and predictable biodegradation. Its anionic nature contributes to improved solubility of hydrophobic actives and viscosity control in aqueous systems.

CarboMer supplies Poly-L-Aspartic Acid, Sodium salt with validated control over molecular weight, polydispersity, sodium content, and residual monomers. Material is suitable for laboratory, pilot, and commercial-scale applications and can be tailored for specific viscosity or chelation requirements.

The material is packaged in sealed, moisture-protective, tamper-evident containers. Minimum order quantities (MOQ), lead times, and documentation, including CoA and SDS, are provided upon request.

Each batch is tested for identity (NMR, IR), molecular weight, Sodium content, loss on drying, pH, residual solvents, and microbial limits. Certificates of Analysis (CoA), Safety Data Sheets (SDS), and full traceability documentation accompany every shipment.
