The Unique Properties of Gamma-Polyglutamic Acid
Gamma-Polyglutamic acid, or g-PGA, is a naturally occurring biopolymer composed of homo-polyamide units of D- and L-Glutamic acid. The polymer’s optically active nature and chiral center in every glutamate unit give it distinct properties, including high hygroscopicity. When in its free acid form, g-PGA is water-insoluble; however, the sodium salt form, as found in SAT-PGA-LW / HW, becomes water-soluble and readily utilized in different formulations.
Applications in Skincare: A Natural Moisturizer
One of the most exciting applications of SAT-PGA-LW / HW is in the skincare industry. Its hygroscopic and moisturizing properties are comparable to hyaluronic acid, making it a highly effective humectant. g-PGA is known to enhance skin elasticity, nourish, and smoothen the skin, while also promoting the production of natural moisturizing factors such as urocanic acid and pyrrolidone carboxylic acid. Studies have shown that g-PGA performs better than hyaluronic acid and soluble collagen in terms of skin hydration and elasticity.

Environmentally Friendly and Biodegradable
SAT-PGA-LW / HW stands out not only for its performance but also for its eco-friendly nature. As an extracellular polymer, g-PGA is fully biodegradable and non-toxic to humans, making it a sustainable alternative to synthetic polymers. Its use in various industries aligns with Satcotek’s commitment to providing natural, sustainable solutions without compromising on quality or performance.
