Propylene Glycol (PG), also known as 1,2-Propanediol, is a synthetic organic compound with the chemical formula C3H8O2 and CAS number 57-55-6. Produced through the hydrolysis of propylene oxide under controlled temperature and pressure conditions, this distilled product meets a minimum purity specification of 99.5%. TICHEM supplies Propylene Glycol in three grade options — Industrial Grade, USP Grade, and EP Grade — each formulated to match specific regulatory and application requirements across commercial procurement channels.
The substance appears as a colourless, transparent liquid with a characteristic mild glycol odour. It is fully miscible with water and demonstrates hygroscopic properties, meaning it readily absorbs moisture from the surrounding environment. These properties make it a versatile functional solvent and carrier fluid used across multiple industrial applications.

Propylene Glycol serves as a raw material in the production of unsaturated polyester resins, epoxy resins, and polyurethane resins. It also functions as a building block for plasticizers, surfactants, emulsifiers, and emulsion breakers used in various chemical processing operations.
When mixed with water, Propylene Glycol lowers the freezing point of the solution, making it suitable for use in aircraft de-icing and anti-icing fluid formulations. It also operates as an antifreeze agent and heat transfer fluid in closed-loop systems where lower toxicity compared to ethylene glycol is a consideration.
In industrial processes, Propylene Glycol functions as an extraction solvent and flotation agent. Its ability to dissolve a wide range of organic and inorganic compounds, combined with its medium viscosity and low vapor pressure, supports its use across multiple solvent-based applications.
USP and EP grade Propylene Glycol is used as a solvent for flavours and food colourings, as a humectant in tobacco products, and as an excipient in pharmaceutical formulations. It also appears in cosmetic and personal care product formulations where regulatory compliance with pharmacopoeia standards is required. Industrial grade Propylene Glycol is not intended for direct food, drug, or cosmetic use.
The minimum order quantity for this product is 1 ton, adapted to bulk purchasing demands of enterprise customers. Three transport packaging options are available: iron drums, IBC totes and ISO tanks, which can be selected based on order volume and logistics conditions. The product originates from China and corresponds to HS code 2905320000 for international trade customs declaration.
Industrial Grade Propylene Glycol meets a minimum purity of 99.5% and is intended for general industrial applications such as chemical manufacturing, heat transfer systems, and solvent extraction. USP and EP grades comply with United States Pharmacopeia and European Pharmacopoeia standards respectively, making them suitable for pharmaceutical, food, and cosmetic applications where stricter impurity controls apply.
Propylene Glycol should be stored in sealed containers in a cool, well-ventilated area away from sources of ignition. The product has a flash point of 104 °C, so standard industrial handling procedures for combustible liquids apply. Containers made of carbon steel or stainless steel are compatible with the product.
When stored under proper conditions in sealed containers, Propylene Glycol maintains its specified properties for an extended period. Users should refer to the Certificate of Analysis provided with each shipment for batch-specific information and recommended storage duration.
Only USP or EP grade Propylene Glycol that meets relevant food-grade regulatory standards is suitable for use in food applications. Industrial grade material is not intended for direct food contact or consumption. Buyers should verify grade specifications and applicable regulatory approvals prior to use in food-related business operations.
