Product Description

Product Overview

Poly-L-Glutamate is a biodegradable polyamino acid polymer derived from L-glutamic acid and widely used in cosmetics, agriculture, biotechnology, and functional material formulations. It is supplied as a powder or aqueous solution for manufacturers developing moisturizing ingredients, nutrient delivery systems, and environmentally friendly polymer applications.

Unlike L-Glutamic Acid, which is a single amino acid molecule, Poly-L-Glutamate consists of repeating glutamic acid units connected into a polymer chain. Its high density of functional carboxyl groups gives it unique water-binding and formulation properties.

What Is Poly-L-Glutamate?

Poly-L-Glutamate, also known as Poly-γ-glutamic acid (γ-PGA) when referring to the naturally occurring form, is a polymer composed of multiple L-glutamic acid molecules linked through peptide bonds.

Commercial Poly-L-Glutamate is commonly produced through microbial fermentation processes and supplied in different molecular weight ranges depending on application requirements. It is widely used in skincare formulations, agricultural products, biotechnology applications, and specialty functional materials.
