Propyl Gallate Powder: A Trusted Antioxidant for Shelf Life Extension
At the core of our Propyl Gallate Powder is its powerful active ingredient, an ester formed from gallic acid and propanol. This compound, also widely known in the industry as propyl 3,4,5-trihydroxybenzoate, works by donating hydrogen atoms to neutralize free radicals. This mechanism effectively slows down the oxidative rancidity of fats and oils, making it an exceptionally efficient guardian against spoilage in various formulations. You might also find it referenced simply as PG in supplier lists.
In the current market, Propyl Gallate remains a go-to synthetic antioxidant for industries ranging from foods and cosmetics to plastics, prized for its cost-effectiveness and potency. While many suppliers offer a standard grade, we specialize in providing Propyl Gallate with superior compressibility and low dust characteristics. This is a critical differentiator. Unlike common antioxidants that are simply fine powders, our PG is engineered for easier and safer handling in industrial mixing processes, reducing waste and improving the working environment.
This unique physical property is a direct benefit of our advanced OEM and custom manufacturing capabilities. We don't just sell a generic product; we can fine-tune the particle size distribution and bulk density of the powder during our proprietary manufacturing process. This means we can produce a Propyl Gallate Powder that is optimized for your specific equipment and final product requirements-whether you need a version that disperses more readily in oils or one that integrates seamlessly into dry blends.
Why our Propyl Gallate Powder?
1.Low-Dust & Enhanced Flow for Uninterrupted Production
Generic Propyl Gallate is a fine, dusty powder that poses inhalation risks, contaminates equipment, and leads to material loss through airborne particles.
- Our Difference: We have engineered a low-dust variant with a proprietary particle size distribution. This results in a >15% reduction in airborne dust compared to standard USP-grade powder.
- Your Benefit: This means a safer work environment, less cross-contamination risk, more accurate automated dosing, and ultimately, higher overall equipment effectiveness (OEE) on your production floor.
2. Unmatched Consistency & Batch-to-Batch Reliability
Inconsistent raw materials are a primary cause of product rework and quality deviations. Many suppliers cannot guarantee physical uniformity.
- Our Difference: Leveraging nearly two decades of process control data, we maintain a strict >99.5% purity while controlling key physical parameters like bulk density (consistently within a ±0.05 g/cm³ range).
- Your Benefit: You get a predictable raw material that behaves the same way in every batch, ensuring your final product's quality, stability, and shelf-life are consistently met, batch after batch.
3. OEM-Driven Customization: We Tailor the Powder to Your Formula
Your product is unique. Why should your antioxidant be a one-size-fits-all solution? Our core strength is our flexible OEM/ODM capability, specifically for Propyl Gallate.
- Our Difference: We don't just sell a standard grade. We can co-create a PG solution with you. This includes customizing:
- Particle Size: Optimized for your mixing technology, whether for high-fat systems or dry blends.
- Carrier Systems: Pre-blended with specific anti-caking agents or other synergistic antioxidants.
- Packaging: Tailored to your JIT (Just-In-Time) inventory needs to reduce waste and storage costs.
- Your Benefit: You solve specific formulation challenges-like achieving perfect dispersion in a difficult matrix or improving compression for tableting-directly at the source, streamlining your own manufacturing process.

Common Applications
1. Food Industry
Used as an antioxidant to prevent oxidation of fats and oils in processed foods. Commonly added to products like baked goods, potato chips, margarine, and meat products to extend shelf life. Often combined with other antioxidants such as BHA (Butylated Hydroxyanisole) and BHT (Butylated Hydroxytoluene) for synergistic effects.
2. Cosmetic Industry
Functions as an antioxidant and stabilizer in formulations such as creams, lotions, lipsticks, and sunscreens. Helps prevent rancidity and color degradation caused by exposure to air and light.
3. Pharmaceutical Industry
Used as a stabilizer in certain pharmaceutical formulations, especially those containing oils or fat-soluble vitamins. Helps maintain the potency and quality of active ingredients during storage.

FAQs
1.Is Propyl Gallate safe for food use?
Yes, Propyl Gallate is approved by major regulatory bodies like the FDA and EFSA for use in limited quantities. However, manufacturers should ensure compliance with local maximum allowable concentrations.
2. Can Propyl Gallate be used together with other antioxidants?
Yes, combining Propyl Gallate with BHA or BHT can enhance overall antioxidant effectiveness due to synergistic effects.
3. Is Propyl Gallate natural or synthetic?
It is a synthetic antioxidant, derived from gallic acid, which naturally occurs in tea leaves and oak bark.
4. How to ensure uniform dispersion in formulations?
Pre-dissolve Propyl Gallate in a small amount of ethanol, propylene glycol, or oil before mixing with the main batch to improve solubility and stability.
5. Is Propyl Gallate suitable for natural or "clean label" products?
Generally, no. As it is synthetic, it's not typically used in "natural" or "organic" formulations. For clean-label alternatives, consider rosemary extract or tocopherols (Vitamin E).
6. Can it be used in pet food or animal supplements?
Yes, within regulatory limits. It helps maintain fat quality and prevent oxidation in animal nutrition products. Always confirm compliance with local feed regulations.
7. What temperature should be avoided during formulation?
Avoid prolonged exposure to temperatures above 80°C, as excessive heat may cause decomposition and reduce antioxidant activity.
8. What's the best way to store Propyl Gallate Powder?
Store it in tightly sealed containers, in a cool (below 25°C), dry, and dark environment to maintain stability and prevent oxidation.
