γ-PGA

γ-PGA (Polyglutamic acid) is a water-soluble, biodegradable, and non-toxic natural polymer produced through microbial fermentation. It is a viscous substance first discovered in natto, a traditional Japanese fermented food. As an anionic natural polymer, it is formed by amide linkages between alpha amino and gamma carboxyl groups, with a molecular weight ranging from 50,000 to 2 million daltons.

It is abundant in natto, and its presence enhances the nutritional value of the food, providing a rich source of vitamins (such as B2, B6, B12, E, K2) and digestive enzymes (such as nattokinase). Beyond being a part of food, it has gained popularity in recent years for its unique biological properties and health benefits, leading to its application across multiple industries, including skincare, dietary supplements, pharmaceuticals, and agriculture.

Due to its significant moisturizing properties,it has become a common ingredient in many skincare products, effectively enhancing skin hydration and improving dryness and signs of aging. In the food industry, γ-PGA is added to supplements to promote mineral absorption, especially in enhancing the absorption of minerals like calcium and iron. Additionally, it's biodegradability makes it widely used in eco-friendly materials and agriculture, serving as a moisture-retaining agent and part of biofertilizers.

Thanks to its non-toxicity, biodegradability, excellent skin compatibility, and environmental friendliness, it is an ideal choice for various applications, and its potential continues to expand as research progresses.

Chinese name: γ-PGA

Foreign name: γ-Polyglutamic acid

Molecular weight: ranging from 5000 to 2 million Daltons, depending on the application field and purity (such as food grade: 100,000-700,000 units; cosmetic grade: 700,000-1.1 million units; pharmaceutical grade: 1.2 million-2 million units)

1.Naturally Derived & Environmentally Friendly
γ-PGA is produced through microbial fermentation of natural glutamic acid, without the use of organic solvents or chemical modifications. This bio-based production process ensures sustainability and eco-friendliness.

2.Excellent Water Solubility
It dissolves quickly in water to form a stable, transparent colloidal solution. This is due to the abundance of carboxyl and amino groups in its molecular structure, which provide strong hydrophilicity.

3.Adjustable Molecular Weight
The molecular weight of it can be customized, allowing for a range of textures from light and fluid to highly viscous. This flexibility is achieved by adjusting fermentation parameters during production.

4.Low Irritation & Skin-Friendly
As a food-grade, naturally derived ingredient, it is non-irritating and hypoallergenic. It is well-tolerated even by sensitive skin, infants, and pregnant women-thanks to its mild chemical structure and excellent biocompatibility.

5.Breathable Film Formation
It forms a soft, breathable, and transparent film on the skin's surface, preventing moisture loss while maintaining a fresh, non-sticky feel. This benefit comes from its flexible, high-molecular-weight polymer chains.

6.Excellent Compatibility with Active Ingredients
It works synergistically with ingredients like hyaluronic acid, glycerin, and niacinamide, improving overall hydration, texture, and formulation stability. This is due to its gentle chemistry and network-forming capacity.

1.Long-lasting Hydration with Strong Moisture Retention
It molecules can hold a large amount of water, forming a breathable moisture barrier on the skin's surface to effectively slow down water loss and provide long-lasting hydration. Its high molecular structure and hydrophilic groups are the key factors behind this.

2.Gentle and Non-Irritating, Suitable for All Skin Types
Naturally derived, free of fragrances, alcohol, and allergens, making it safe for sensitive skin, babies, and pregnant women. Its high safety profile comes from its natural amino acid composition and microbial fermentation process.

3.Synergistic Effect, Enhancing Absorption of Active Ingredients
It improves the skin's hydration status in the stratum corneum, helping nutrients penetrate more effectively, thus boosting the absorption of ingredients like hyaluronic acid and Vitamin C. This synergy stems from its ability to optimize the skin's microenvironment.

4.Sustainable and Eco-friendly, Aligns with Clean Beauty Trends
Derived from glutamic acid through microbial fermentation, it is naturally sourced and produced in an eco-friendly process, meeting the requirements of clean beauty and sustainable brands. Its advantages lie in its low-carbon manufacturing path and renewable raw materials.

Q1: Are there any ingredients that should be avoided when using it?
A: it is generally compatible with most cosmetic and food ingredients. However, it may degrade in strongly acidic or alkaline environments, so it's best not to combine it with high concentrations of strong acids or bases.

Q2: Is it suitable for all skin types?
A: Yes. It is gentle and naturally derived, making it suitable for dry, oily, and sensitive skin. However, for individuals with extremely sensitive or reactive skin, a patch test is recommended before use.

Q3: Are there any potential irritation or allergy risks associated with it?
A: No significant cases of irritation or allergy have been reported. It is a food-grade fermented ingredient with a high safety profile. Still, individual differences exist, so it's advisable to monitor for skin reactions during first-time use.

Q4: What are the recommended storage conditions for it?
A: Store in a cool, dry place away from light. Keep sealed and avoid moisture exposure after opening. Direct contact with water should be avoided to maintain product stability.

Q5: Can it be used in ingestible (oral) products?
A: If produced under food-grade standards, it can be used in food or dietary supplements. However, formulation must comply with local regulatory guidelines for safe and approved usage.

Q6: Will prolonged use of it lead to skin dependency?
A: No. It works on the skin's surface without affecting internal biological functions. It does not cause physiological dependency.

Q7: What types of products is it best suited for?
A: It is widely used in hydrating skincare products such as serums, masks, and creams, as well as in functional foods, nutritional supplements, drug delivery systems, and agricultural moisturizers.
