Propylene Glycol (PG), also chemically known as propane-1,2-diol, stands as a cornerstone chemical compound due to its exceptional versatility and widespread applications across numerous industries. As a clear, colorless, nearly odorless, and slightly viscous liquid with a faintly sweet taste, PG is highly valued for its unique blend of properties. NINGBO INNO PHARMCHEM CO.,LTD. proudly offers high-quality Propylene Glycol, catering to the exacting standards of diverse sectors worldwide.

Chemically classified as a diol, Propylene Glycol is notably hygroscopic, meaning it readily attracts and retains moisture. This property makes it an indispensable humectant. It is also completely miscible with a wide array of solvents, including water, acetone, and chloroform, facilitating its integration into complex formulations. Generally, PG exhibits low volatility and is considered non-irritating, ensuring safety and ease of handling in various applications. Its stability and functional characteristics make it an ideal choice for maintaining product integrity and consistency.

The industrial production of Propylene Glycol primarily involves the hydration of propylene oxide. This process is meticulously controlled to yield high-purity grades, including those suitable for pharmaceutical and food applications. Through advanced purification methods, NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Propylene Glycol meets stringent quality specifications, making it a reliable raw material for sensitive products.

The applications of Propylene Glycol are remarkably diverse:

• Food and Beverage Industry: Approved as a food additive (E1520 in Europe, GRAS by the US FDA), PG serves multiple functions. It acts as an effective humectant, preventing dryness and maintaining moisture in baked goods, confections, and snack foods. It also functions as an emulsifier, a stabilizer, and a solvent for flavors, colors, and antioxidants in products ranging from soft drinks and alcoholic beverages to sauces and salad dressings.
• Pharmaceuticals and Cosmetics: In pharmaceutical formulations, PG is widely utilized as a solvent and carrier for oral, injectable, and topical medications, improving the solubility and bioavailability of active ingredients. For cosmetics and personal care products (E490), its humectant properties help moisturize skin, while its role as a viscosity-decreasing agent and fragrance ingredient enhances product texture and performance in items such as lotions, creams, shampoos, and deodorants. Its film-forming capabilities also offer protective benefits.
• Industrial and Other Applications: Beyond consumer products, Propylene Glycol is an important component in industrial settings. It serves as a non-toxic antifreeze and de-icing agent, particularly favored in situations where environmental exposure or accidental ingestion is a concern, such as aircraft de-icing and RV/marine antifreeze. It is also used in the production of polyurethanes, paints, coatings, and as a defoamer in various industrial processes, including theatrical fog production.

From a safety perspective, Propylene Glycol is recognized for its low toxicity profile when used in typical amounts. It is efficiently metabolized in the human body into natural compounds like pyruvic acid, acetic acid, and lactic acid, and rapidly excreted within approximately 48 hours. Cases of toxicity are exceedingly rare and typically arise from extremely high exposures in specific medical contexts or accidental large ingestions, rather than from normal dietary or cosmetic use. While individuals with impaired kidney or liver function, as well as infants and pregnant women, may require cautious consideration at very high doses, the general safety of PG for its approved uses is well-established. It is also noted for its general non-irritating nature to skin, though mild contact dermatitis can occur in sensitive individuals. Furthermore, Propylene Glycol is biodegradable, posing a low environmental impact.
