Three Grades of Propylene Glycol Shipped Together by Henan Tongshang

Today, Henan Tongshang completed a representative propylene glycol shipment from our warehouse. One dedicated freight truck carried three different grades of 1,2-Propylene Glycol, CAS No. 57-55-6, which are among the main propylene glycol products supplied by Henan Tongshang.

From the real loading photo, buyers can clearly see the differences in packaging, drum labels, and brand identification among these three products.

Original Shell Propylene Glycol (MPG)
The Shell MPG is packed in original heavy-duty steel drums with a special internal coating. The drum label carries clear Shell brand identification and relevant product information. This product is controlled at 99.8% purity or above, and some batches may test around 99.9%. With low color and light odor, it is commonly used as a stable solvent in applications with higher quality requirements, such as flavors and fragrances, e-liquid formulations, and premium personal care products.

Domestic Pharmaceutical Grade Propylene Glycol
This product is supplied by qualified domestic manufacturers with relevant pharmaceutical-grade production capabilities. The drum label follows standard labeling requirements. With purity ≥99.8%, this grade has stricter control over indicators such as heavy metals, chlorides, and reducing substances. It is mainly supplied to pharmaceutical companies for compliant applications such as formulation solvents and soft capsule plasticizers.

Domestic Industrial Grade Propylene Glycol
The industrial grade propylene glycol is packed in recognizable galvanized iron drums. With purity ≥99.5%, it offers a practical cost-performance advantage. It is widely used in unsaturated polyester resin, polyurethane resin production, industrial antifreeze, and coating film-forming auxiliaries.

The photo shows the real loading scene of three different propylene glycol grades shipped together. The corresponding factory COA documents for each batch have been placed in the truck document bag, and the goods are now on the way to the destination.
