Propylene Glycol (PG), identified by CAS number 57-55-6, is a chemical compound with a fascinating set of properties that dictate its widespread use. Understanding its chemical structure, physical characteristics, and safety profile is crucial for anyone utilizing this versatile substance.

Chemically, Propylene Glycol is a synthetic organic compound with the formula C3H8O2. It is classified as a diol, meaning it contains two hydroxyl (-OH) groups. This vicinal diol structure is key to its functionality. It is a colorless, nearly odorless, and slightly viscous liquid at room temperature. Its high miscibility with water, ethanol, acetone, and chloroform makes it an exceptionally useful solvent for a broad spectrum of substances. The propylene glycol solvent properties are central to its utility across various industries.

The physical properties of PG, such as its low volatility and relatively low toxicity, contribute significantly to its safe handling and application. Its low vapor pressure means it does not readily evaporate, making it suitable for applications where prolonged contact or slow release is desired, such as in humectants or some industrial fluids. The propylene glycol chemical formula and structure allow it to act effectively as a humectant, attracting and retaining moisture, which is vital in cosmetics and food products.

From a safety perspective, Propylene Glycol is widely recognized for its low toxicity. It has been approved by regulatory bodies such as the U.S. Food and Drug Administration (FDA) as 'Generally Recognized As Safe' (GRAS) for use in food and has an E-number (E1520) for food applications in the European Union. Its USP grade signifies a high level of purity suitable for pharmaceutical and cosmetic uses. While generally safe, particularly in the low concentrations found in consumer products, high doses or specific medical administrations can lead to adverse effects, which are thoroughly documented in safety data sheets. Understanding the propylene glycol safety considerations is paramount for responsible use.

Common synonyms for Propylene Glycol include 1,2-propanediol, propane-1,2-diol, and methyl ethyl glycol. These different names often appear in technical literature and product labels, highlighting the compound's extensive presence across scientific and commercial domains. Whether referred to by its primary name or its synonyms, the essential properties of PG remain consistent.
