Propylene Glycol, commonly known as MPG, is a remarkable synthetic organic compound with the chemical formula C3H8O2 and CAS number 57-55-6. This colorless, nearly odorless, and tasteless liquid is highly versatile, serving as a cornerstone ingredient across numerous industrial, pharmaceutical, and food-related applications. Its unique properties, including its excellent solvency, humectancy, and low toxicity, make it indispensable for enhancing product quality and stability.

NINGBO INNO PHARMCHEM CO.,LTD. specializes in the production and supply of high-purity Propylene Glycol, meeting stringent quality standards for various grades. Our offerings include USP (United States Pharmacopeia) grade, Food grade, and Industrial grade Propylene Glycol, ensuring suitability for diverse customer requirements worldwide. The USP grade signifies compliance with pharmacopeial standards, making it ideal for pharmaceutical and high-purity applications, while Food grade meets the strict safety criteria for human consumption.

In the food industry, Propylene Glycol acts as a multi-functional additive. It is widely utilized as a humectant, effectively absorbing and retaining moisture to prevent baked goods like bread and cakes from drying out, thus extending their freshness and shelf life. As an excellent solvent, it aids in the uniform dispersion of food flavors and pigments, ensuring consistent taste and color in beverages and other food products. Furthermore, its antifreeze properties are crucial in frozen foods, preventing the formation of large ice crystals that can degrade texture and taste in items such as ice cream. It also functions as a thickener, emulsifier, stabilizer, anti-caking agent, and antioxidant, playing a vital role in maintaining the consistency, appearance, and shelf life of processed foods, from salad dressings to powdered drink mixes.

Beyond food, Propylene Glycol is extensively used in the pharmaceutical and cosmetic sectors. In medicines, it serves as a crucial drug solubilizer, a stabilizer for vitamins, and a water-miscible co-solvent, enhancing the efficacy and shelf life of various drug formulations. For cosmetics and personal care products, its humectant properties make it an excellent moisturizer in creams, lotions, and shampoos, helping to retain skin and hair moisture. It also prevents bacterial growth in these formulations, contributing to product longevity and safety. Industrially, MPG finds applications in engine coolants, airplane deicers, and as a component in the production of enamels, paints, and polyurethane cushions.

Regarding safety and regulatory aspects, Propylene Glycol has been the subject of considerable discussion. In the United States, the Food and Drug Administration (FDA) classifies it as "Generally Recognized As Safe" (GRAS) for use as a food additive. This classification indicates that when used at current or reasonably expected levels, it poses no significant hazard to public health. The human body metabolizes Propylene Glycol, converting it into lactic acid, which is then typically removed by the kidneys. While generally safe, very high doses or consumption by individuals with impaired kidney or liver function, infants, or burn patients may lead to toxicity, though such cases are rare and usually associated with medical over-administration rather than dietary intake. It is crucial to distinguish Propylene Glycol from ethylene glycol, a highly toxic compound often mistakenly associated with it due to its use in industrial antifreeze. Propylene Glycol-based antifreeze, by contrast, is considered non-toxic.

The regulatory landscape differs somewhat in Europe. While Propylene Glycol is not completely banned, the European Union enforces stricter regulations and lower permissible limits for its use in food products compared to the U.S. This difference stems from Europe's more precautionary approach to chemical regulation, exemplified by its stringent REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) program, which prioritizes public health and environmental protection. Despite these varying limits, Propylene Glycol remains an approved and safe additive in European food, cosmetic, and pharmaceutical applications when used within specified guidelines.
