1,2-Propylene glycol is an organic compound that, at room temperature, appears as a colorless, odorless, and slightly sweet-tasting viscous liquid. It is one of the major isomers of propylene glycol and is characterized by its hygroscopicity, excellent solubility, and low toxicity; consequently, it is widely utilized across various fields, including food, pharmaceuticals, cosmetics, tobacco, and industry. As a key chemical raw material, 1,2-propylene glycol is primarily used in the production of unsaturated polyester resins, epoxy resins, and similar materials, while also serving as an antifreeze, lubricant, humectant, and solvent.

Function

In the food industry, 1,2-propanediol (E1520) is primarily utilized as a food additive, serving functions such as a stabilizer, firming agent, anti-caking agent, defoamer, emulsifier, and humectant. It is frequently incorporated into fresh moist noodle products (such as noodles and dumpling wrappers) and pastries to preserve the product’s moisture content and palatability, while also improving its texture.

In the pharmaceutical sector, 1,2-propanediol is a commonly used pharmaceutical excipient, widely employed in various formulations including injections, oral solutions, ointments, and suppositories. It primarily functions as a solvent, co-solvent, plasticizer, humectant, and antifreeze agent, helping to enhance the solubility and stability of medications. For instance, propylene glycol is included as a solvent in diazepam injections.

In the daily chemical and personal care industry, 1,2-propanediol is used in products such as toothpaste, facial cleansers, shampoos, and cosmetics; acting as a humectant, wetting agent, and solvent, it helps to soften the skin and minimize moisture evaporation. In the tobacco industry, it serves as a humectant and anti-mold agent for tobacco, helping to maintain the tobacco’s moisture level and flavor profile. Furthermore, it is one of the primary ingredients found in e-liquids for electronic cigarettes.
