What Is It?

Sodium polyglutamate is a water-soluble, biodegradable biopolymer produced through the microbial fermentation of glutamic acid. Structurally, it is a long chain of glutamate molecules linked together, forming a polymer that is:

Highly water-absorbent;

Stable under various conditions;

Safe and eco-friendly;

Because of these properties, it has been applied across multiple industries. Whether you are developing hydrating skincare formulas, agricultural water retention products, or biomedical materials, it offers versatility and strong performance.

Functions:

Different molecular weight for skincare:

♦Long-lasting hydration with a silky feel

PGA-HMW contains a high number of hydrophilic side chains, which gives it a remarkable ability to lock in moisture. At the same time, it delivers a smooth, silky, and refreshing skin feel, effectively reducing the sticky sensation that is often associated with hyaluronic acid.

♦Moisturizing and brightening, working in synergy with HA

PGA-LMW helps inhibit the activity of hyaluronidase in the skin, which enhances the stability of hyaluronic acid and increases its overall content. In addition, it can also gently inhibit tyrosinase activity, supporting a mild yet effective brightening effect.

♦Boosts natural moisturizing factors in the skin

PGA-Oligo, with its very low molecular weight (below 10 kDa), penetrates the skin more efficiently, leaving it plump and hydrated. Moreover, it helps increase the NMF (natural moisturizing factor) content in the stratum corneum, thereby strengthening the skin’s water retention capacity.
