Poly-L-Glutamic Acid(CAS: 25513-46-6)

Poly-L-Glutamic Acid (CAS: 25513-46-6) is a biodegradable, water-soluble polymer composed of repeating L-glutamic acid units. Its chemical formula is (C5H9NO3)n, and it exhibits negative charge due to carboxylic acid groups. It is known for its high viscosity, pH responsiveness, and applications in pharmaceuticals, cosmetics, and food industries.

Poly-L-Glutamic Acid (CAS: 25513-46-6) is widely used in pharmaceuticals as a drug delivery carrier, in cosmetics for skin moisturizing, in food as a natural thickener and flavor enhancer, and in research for biocompatible materials. It also serves as a flocculant in industrial processes and a stabilizer in biotechnology applications.

Poly-L-Glutamic Acid (CAS: 25513-46-6) is generally considered safe when handled properly. It has low toxicity and is approved for use in food and pharmaceuticals by regulatory bodies like the FDA. Precautions include avoiding inhalation of powder and using protective gloves during handling to ensure safety in industrial settings.

Poly-L-Glutamic Acid (CAS: 25513-46-6) should be stored in a cool, dry place (15-25°C), away from moisture and direct light. Use airtight, dark-colored containers to maintain stability and prevent degradation. Ensure storage in a well-ventilated area and avoid contamination to preserve its chemical integrity.
