Alcohols; acyclic, diols; propylene glycol (propane-1, 2-diol)

HS v2017 Code: 290532

About alcohols; acyclic, diols; propylene glycol (propane-1, 2-diol)

HS code 290532 covers the classification of propylene glycol, a widely used organic compound that belongs to the group of acyclic diols. Propylene glycol is a colorless, odorless, and viscous liquid with a wide range of applications in various industries, including pharmaceuticals, cosmetics, food, and automotive. Its versatility and importance in the global economy make it a significant commodity within the broader chemical industry.

Production process

Propylene glycol is primarily produced through the hydrolysis of propylene oxide, which is derived from the oxidation of propylene. The production process typically involves the reaction of propylene oxide with water in the presence of an acid or base catalyst to yield propylene glycol. Distillation and purification steps are then used to obtain the desired purity levels for commercial applications.

Production inputs

The main inputs required for the production of propylene glycol include propylene, a key petrochemical feedstock, as well as water, catalysts, and energy sources. Specialized equipment, such as reactors, distillation columns, and purification systems, are also essential for the manufacturing process.

Production outputs

Propylene glycol, the primary output of HS code 290532, is widely used in a variety of industries. It is a key ingredient in 330499 Cosmetic and toilet preparations, not elsewhere specified or included, 300490 Medicaments, not elsewhere specified or included, and 381700 Mixed alkylbenzenes and mixed alkylnaphthalenes, not elsewhere specified or included. Additionally, propylene glycol is used in the production of 382200 Composite diagnostic or laboratory reagents, not elsewhere specified or included and 382490 Chemical products and preparations of the chemical or allied industries, not elsewhere specified or included.
