Product Description
Poly-L-Arginine is a biodegradable amino acid-based polymer ingredient composed of repeating L-arginine units, used in biotechnology, cosmetic formulations, and specialty material applications. It is supplied as a high-quality polymer powder for manufacturers developing functional biomaterials, delivery systems, and advanced formulations requiring a cationic amino acid polymer.
Unlike L-Arginine, which is a single amino acid molecule, Poly-L-Arginine is a polymer chain formed by linking multiple L-arginine molecules. Its positively charged structure provides unique interaction properties, making it valuable for research, biomaterial development, and specialized formulation applications.
Poly-L-Arginine is a synthetic polypeptide composed of L-arginine amino acid residues connected through peptide bonds. As an amino acid-derived polymer, it belongs to the class of cationic polypeptides and is widely studied for its molecular interaction and material properties.
Commercial Poly-L-Arginine is generally produced through controlled polymerization processes and supplied in different molecular weight ranges depending on application requirements. It is typically available as a white to off-white powder with defined polymer characteristics.

Poly-L-Arginine is widely used in biotechnology research and biomaterial development due to its cationic peptide structure and ability to interact with biological molecules.
Poly-L-Arginine can be incorporated into specialty cosmetic formulations where amino acid-based polymers are selected for their formulation properties and material characteristics.
Due to its positively charged polymer structure, Poly-L-Arginine is studied in specialized research applications involving molecular interaction and delivery system development.
For buyers sourcing Poly-L-Arginine, molecular weight distribution and polymer characteristics are the most important evaluation factors. Unlike simple Amino Acids, polymer performance depends strongly on chain length, degree of polymerization, and application-specific requirements.
| Selection Factor | Why It Matters | Typical Buyer Consideration |
|---|---|---|
| Molecular Weight Range | Influences viscosity, interaction behavior, and application performance | Select according to biotechnology, cosmetic, or material application requirements |
| Polymer Structure | Determines charge characteristics and functional properties | Confirm polymer type and analytical specifications |
| Purity Level | Affects formulation consistency and research reliability | High-purity grades are commonly preferred for specialty applications |
| Quality Documentation | Supports supplier qualification and technical evaluation | COA, TDS, SDS, and analytical reports are commonly requested |
