[ Introduction ]
Polyglutamic Acid (PGA) is a natural polymer formed by the polymerization of glutamic acid monomers through amide bonds, typically produced via microbial fermentation (e.g., using Bacillus subtilis). It exhibits excellent biocompatibility, biodegradability, and multifunctionality, and is widely used in cosmetics, pharmaceuticals, food, and agriculture.

[ Uses ]
Cosmetics/Skincare: Serves as a highly effective moisturizing agent, with a stronger moisture retention capacity than Hyaluronic Acid, and helps strengthen the skin barrier.
Pharmaceuticals: Can be used as a drug carrier, tissue engineering material, and hemostatic agent.
Food: Naturally present in Japanese natto and also used as a food thickener and texture enhancer.
Agriculture: Can be applied as a soil conditioner to improve fertilizer utilization.
