Propylene Glycol (PG) is a versatile chemical compound utilized across a spectrum of industries, from food and pharmaceuticals to industrial manufacturing. Its efficacy and safety depend significantly on its grade, which dictates its purity and suitability for specific applications. Understanding these different grades—Food Grade, USP Grade, and Industrial Grade—is crucial for manufacturers seeking the optimal PG for their products. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of PG grades to cater to diverse industry requirements.

Food Grade Propylene Glycol

Food Grade PG is manufactured to meet stringent purity standards set by regulatory bodies like the FDA. It is used in food products as a humectant, solvent, stabilizer, and preservative. Its low toxicity makes it safe for consumption and widely employed in baked goods, beverages, flavorings, and more. When exploring uses of propylene glycol in food, ensuring it is Food Grade is paramount for compliance and consumer safety.

USP Grade Propylene Glycol

USP Grade PG meets the standards established by the United States Pharmacopeia. This grade is highly pure and suitable for use in pharmaceuticals, medicines, and cosmetics. Its applications range from drug solvents and excipients to moisturizers in skincare and hair care products. The reliability of USP Grade PG ensures product integrity in sensitive formulations.

Industrial Grade Propylene Glycol

Industrial Grade PG is produced for applications where the ultra-high purity of Food or USP grades is not strictly necessary. It is commonly used in antifreeze, coolants, hydraulic fluids, aircraft de-icing fluids, and as a chemical intermediate in manufacturing resins and coatings. While still considered low in toxicity compared to ethylene glycol, its applications are primarily technical rather than consumer-facing where direct ingestion is a risk. Understanding industrial applications of propylene glycol helps in selecting the correct grade.
