Polyglutamic Acid

Product Overview

Polyglutamic Acid (PGA), also known as γ-PGA, is a naturally occurring biopolymer composed of glutamic acid units linked by amide bonds. As a high-performance cosmetic active ingredient, it is renowned for its exceptional water retention capabilities and biocompatibility. Our premium grade Polyglutamic Acid is manufactured under strict quality control standards to ensure consistency and safety for personal care applications. This macromolecule serves as a superior alternative to traditional moisturizing agents, providing long-lasting hydration without a greasy residue.

Key Functional Benefits

The unique molecular structure of Polyglutamic Acid allows it to form a breathable film on the skin surface, effectively locking in moisture and protecting against environmental stressors. Unlike some synthetic polymers, PGA is biodegradable and non-irritating, making it suitable for sensitive skin formulations. Key advantages include:

• Superior moisture retention compared to hyaluronic acid in certain conditions.
• Enhances skin elasticity and firmness through improved hydration levels.
• Reduces the appearance of fine lines caused by dryness.
• Improves the sensory feel of formulations, providing a smooth texture.
• Compatible with a wide range of cosmetic ingredients and emulsion systems.

Technical Specifications

Our manufacturing process ensures high purity and consistent molecular weight distribution. Below are the typical specifications for our bulk supply:

Industrial Applications

This ingredient is versatile and widely used across various personal care categories. It is particularly effective in leave-on products where sustained hydration is required. Formulators utilize PGA in serums, creams, lotions, and masks to boost moisturizing performance. Additionally, it functions well in hair care products such as shampoos and conditioners to improve manageability and shine. The polymer can be used alone or synergistically with hyaluronic acid to mitigate stickiness while enhancing overall efficacy. Recommended dosage levels typically range from 0.1% to 1.0% depending on the desired viscosity and effect.

Storage and Handling

To maintain optimal quality, Polyglutamic Acid should be stored in a cool, dry place away from direct sunlight. Containers must be kept tightly closed to prevent moisture absorption, which could affect flowability. The recommended storage temperature is below 25°C, though short-term exposure to ambient conditions during shipping is acceptable. For long-term preservation, storing at -20°C is advised. We offer flexible packaging options, including 25kg drums, customized to meet specific logistical requirements.

Quality Assurance

As a global manufacturer, we provide comprehensive documentation including Certificates of Analysis (COA) with every batch. Our production facilities adhere to rigorous safety and quality protocols to ensure that all chemical inputs meet international regulatory standards. We are committed to supporting our partners with technical data and formulation guidance to facilitate successful product development.
