1,2-Propanediol

Description:

1,2-Propanediol, also known as propylene glycol, is a colorless, odorless, and hygroscopic liquid with the chemical formula C3H8O2. It is a diol, meaning it contains two hydroxyl (-OH) groups, which contribute to its solubility in water and various organic solvents. This compound is non-toxic and has a low vapor pressure, making it suitable for a wide range of applications. It is commonly used as a humectant in food and cosmetics, a solvent for pharmaceuticals, and an antifreeze agent in automotive and industrial applications. Additionally, 1,2-propanediol exhibits low toxicity and is generally recognized as safe (GRAS) by the FDA for use in food products. Its ability to retain moisture makes it valuable in personal care formulations, while its stability under heat and pressure enhances its utility in various chemical processes. Overall, 1,2-propanediol is a versatile compound with significant industrial and consumer applications.

Propylene glycol

CAS: 57-55-6

Propylene glycol is a clear, colorless, viscous liquid that has a low freezing point. It is used as a solvent and as an additive to various foods and medications. Propylene glycol can be used in the analysis of glycols in human serum. This is done by adding propylene glycol to human serum and then analyzing the sample with gas chromatography-mass spectroscopy (GC-MS). The GC-MS analysis can be done on the whole serum or on specific proteins such as surface glycoproteins. Propylene glycol also plays an important role in body formation by supplying propylene units for the synthesis of polypeptides and lipids.
