Propylene Glycol (PG) is a critical chemical with distinct grades tailored for specific applications. At NINGBO INNO PHARMCHEM CO.,LTD., we help clients navigate the choice between USP Grade and Industrial Grade Propylene Glycol to ensure optimal performance and regulatory compliance.

USP Grade Propylene Glycol meets the rigorous standards set by the United States Pharmacopeia, signifying exceptional purity. This makes it the preferred choice for applications involving direct human contact or consumption, such as in pharmaceuticals, cosmetics, and food products. Its use as a pharmaceutical ingredient, a cosmetic ingredient, and a food additive is widespread due to its proven safety and efficacy. When developing medications, beauty products, or edible items, USP Grade PG ensures the highest level of safety and quality.

Industrial Grade Propylene Glycol, while still possessing excellent properties, is formulated for applications where extreme purity is not the primary requirement. It is commonly used in antifreeze, de-icing fluids, heat transfer systems, and various manufacturing processes. Its cost-effectiveness and robust performance in these demanding environments make it a valuable choice for many industrial applications. For instance, as an antifreeze, its ability to lower freezing points and prevent corrosion is highly prized.

The selection between these grades hinges on the intended use. For any application involving ingestion, inhalation, or direct skin application where safety is paramount, USP Grade is essential. For industrial processes like cooling systems or chemical manufacturing, Industrial Grade often provides a more economical yet highly effective solution. NINGBO INNO PHARMCHEM CO.,LTD. offers both grades, ensuring that you can source the precise Propylene Glycol product your business needs, whether for sensitive pharmaceutical formulations or robust industrial processes.
