NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of Propylene Glycol (PG), and understanding its fundamental chemical properties is crucial for appreciating its widespread applications. Propylene Glycol, with the molecular formula C3H8O2, is a diol – an organic compound containing two hydroxyl (-OH) groups. This diol structure is responsible for many of its valuable properties, including its hygroscopic nature and its ability to act as a solvent for a wide range of substances.

The physical characteristics of high-purity Propylene Glycol are noteworthy. It is a clear, colorless, viscous liquid with a faintly sweet taste and a mild odor. Its low vapor pressure and high boiling point (around 188°C) make it suitable for applications where evaporation is not desired. The key to its versatility lies in its ability to mix readily with water and many organic solvents, a property attributed to the polar hydroxyl groups. When you buy Propylene Glycol, ensuring its 99.5% purity is essential for predictable performance across various industries.

Propylene Glycol is primarily synthesized through the hydration of propylene oxide. This process involves reacting propylene oxide with water under controlled conditions, often with the aid of a catalyst. The reaction yields a mixture of mono-, di-, and tri-propylene glycols, from which high-purity Propylene Glycol is then separated and purified. The meticulous purification process undertaken by manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. ensures that the final product meets stringent quality standards, whether for use as a food humectant, a cosmetic moisturizer, or a pharmaceutical solvent.

Understanding the science behind Propylene Glycol – from its molecular structure to its production methods – underscores why it is such a critical ingredient. The consistent quality and reliable supply of 99.5% Propylene Glycol from NINGBO INNO PHARMCHEM CO.,LTD. empower industries to innovate and deliver superior products. Exploring its specific chemical properties, like its role as a plasticizer in coatings or as a solvent in inks, reveals its broad industrial significance.
