Polyglutamic Acid

Polyglutamic Acid, commonly known as γ-PGA or Gamma-Polyglutamic Acid, is a natural, biodegradable, and non-toxic biopolymer produced through microbial fermentation of glutamic acid by Bacillus species, such as Bacillus subtilis and Bacillus anthracis. First discovered in the capsule of Bacillus anthracis and abundant in the sticky substance of traditional Japanese natto, γ-PGA is a homogeneous polypeptide composed of glutamic acid units linked by γ-peptide bonds between γ-carboxyl and α-amino groups, with a molecular weight ranging from 100 kDa to 10,000 kDa. Unlike synthetic polymers, it is eco-friendly, skin-friendly, and highly versatile, making it a sought-after ingredient across multiple industries. As a rising star in biotech materials, γ-PGA is gaining global attention for its unique properties and wide-ranging applications, becoming a key component in cosmetics, agriculture, food, pharmaceuticals, and environmental protection.

Key Benefits of Polyglutamic Acid (γ-PGA)

Polyglutamic Acid stands out for its exceptional functional properties, which make it superior to many traditional ingredients and suitable for diverse industrial needs. Its core benefits are backed by scientific research and practical applications:

Superior Moisturizing Ability: γ-PGA has 2-3 times stronger water-absorbing and water-retention capacity compared to hyaluronic acid (HA), the gold standard in moisturizing ingredients. It can form a breathable, moisture-locking film on the skin surface, reduce transepidermal water loss (TEWL), and keep the skin hydrated, soft, and elastic for a long time. This makes it ideal for addressing dryness, dullness, and rough skin.

Biodegradable & Non-Toxic: As a natural biopolymer, γ-PGA is fully biodegradable, breaking down into non-harmful glutamic acid (an essential amino acid for the human body) that poses no risk to the environment or human health. It is non-irritating, non-allergenic, and compatible with human skin and various biological systems, making it safe for long-term use in cosmetics, food, and pharmaceuticals.

Metal Chelation & Detoxification: γ-PGA contains a large number of carboxyl groups, enabling it to effectively chelate heavy metal ions (such as Pb²⁺, Cu²⁺, Cd²⁺, and Cr³⁺) in soil and water, reducing heavy metal pollution and protecting ecological systems. In the human body, it can help inhibit the absorption of harmful heavy metals, supporting internal detoxification.

Nutrient Enhancement & Absorption Promotion: In agriculture, γ-PGA can improve the solubility and availability of nutrients (such as phosphorus, calcium, magnesium, and trace elements) in soil, preventing nutrient precipitation and promoting their absorption by crop roots. In food and pharmaceuticals, it enhances the absorption of minerals (e.g., calcium) and bioactive substances, boosting their efficacy.

Thickening & Stabilizing Properties: γ-PGA has excellent viscosity and film-forming ability, serving as an effective thickener, stabilizer, and emulsifier in food, cosmetics, and industrial products
