Polyglutamic Acid (PGA) – Frequently Asked Questions (FAQ)

1. What is Polyglutamic Acid (PGA)?

Polyglutamic Acid (PGA) is a naturally derived biopolymer produced through the microbial fermentation of Bacillus subtilis. It is known for its strong water-binding capacity and skin-conditioning effects, offering excellent moisturizing, elasticity-enhancing, and barrier-strengthening benefits.

2. What are the main benefits of Polyglutamic Acid in cosmetics and skincare?

PGA provides multiple functional benefits:

• Retains moisture 4–5 times more effectively than hyaluronic acid.

• Forms a soft, breathable film on the skin surface to reduce transepidermal water loss (TEWL).

• Enhances skin smoothness, elasticity, and barrier function.

• Promotes long-lasting hydration and a plump, radiant complexion.

---

3. How is Polyglutamic Acid produced?

Our Polyglutamic Acid is produced via advanced microbial fermentation technology, followed by high-purity filtration and drying processes. This ensures a clean, stable, and biodegradable product with minimal impurities, meeting international cosmetic and nutraceutical standards.

---

4. What are the typical applications of Polyglutamic Acid?

PGA is widely used in:

• Cosmetics & Personal Care: Moisturizers, serums, masks, lotions, and anti-aging products.

• Health Supplements: Oral beauty products, hydration-support formulas, and joint-support supplements.

• Pharmaceuticals & Food Industry: As a biopolymer, thickener, stabilizer, or controlled-release agent.

5. What is the difference between Polyglutamic Acid and Hyaluronic Acid?

While both are effective moisturizers, Polyglutamic Acid retains water more efficiently and prevents moisture loss by forming a protective film. Hyaluronic Acid mainly hydrates from within, while PGA enhances surface moisture retention and supports the skin barrier — making them excellent when used together.

---

6. Is Polyglutamic Acid safe and biodegradable?

Yes. Polyglutamic Acid is non-toxic, non-irritating, and fully biodegradable. It’s derived from natural fermentation and widely recognized as safe for use in cosmetics, food, and pharmaceutical applications.

---

7. What grades or specifications are available?

We offer Cosmetic Grade and Food/Nutraceutical Grade PGA with different molecular weights and purity levels. Custom formulations are available to meet specific application needs.

---

8. How should Polyglutamic Acid be stored and handled?

Store in a cool, dry, and well-ventilated place, away from direct sunlight and moisture. Reseal tightly after use to maintain product quality and stability.

---

9. What packaging options are available for bulk supply?

Standard packaging: 1 kg aluminum foil bags or 25 kg fiber drums, with customized packaging available upon request for OEM and bulk orders.

---

10. Does your Polyglutamic Acid comply with international quality standards?

Yes. Our PGA is manufactured under ISO9001, ISO22000, and HACCP systems, and each batch undergoes COA, HPLC, and microbiological testing to ensure consistent quality and safety for global B2B clients.
