Propylene Glycol (PG), chemically known as propane-1,2-diol (CAS 57-55-6), is a colorless, odorless, and viscous liquid with a faintly sweet taste. It is an aliphatic diol, widely recognized for its exceptional versatility and low toxicity, making it a cornerstone ingredient across numerous industries. Unlike ethylene glycol, which is highly toxic, propylene glycol is generally considered safe for consumption and environmental release, highlighting its superior safety profile for a broad array of uses. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying high-quality Propylene Glycol that meets stringent industry standards.

Our Propylene Glycol boasts a purity exceeding 99%, ensuring its efficacy and safety for sensitive applications. Its inherent properties, such as its ability to dissolve a wide range of substances (including water, acetone, and chloroform), act as a humectant (moisture-retaining agent), and function as a stabilizer, make it indispensable. Furthermore, its low volatility and general non-irritating nature contribute to its widespread acceptance and application globally. We adhere to rigorous quality control protocols, holding ISO 9001 certification to guarantee consistent product excellence.

The applications of Propylene Glycol are remarkably diverse, spanning from consumer goods to industrial processes:

Food and Beverage Industry: Propylene Glycol is designated as Generally Recognized As Safe (GRAS) by the US Food and Drug Administration (FDA) and is approved for food manufacturing (E-number E1520 in the European Union). It serves multiple functions, including as an anticaking agent to prevent clumping in powdered products, an emulsifier to blend otherwise immiscible ingredients, a flavoring agent, a humectant to maintain moisture in baked goods and candies, and a stabilizer. It is commonly found in drink mixes, dressings, dried soups, cake mixes, soft drinks, and even beer, where it helps stabilize foam. It can also act as a solvent for various spices, pigments, and preservatives, ensuring even distribution and enhanced product quality.

Pharmaceuticals and Cosmetics: In the pharmaceutical sector, Propylene Glycol is widely used as a solvent and carrier for numerous oral, injectable, and topical drug formulations, enabling the dissolution and delivery of active pharmaceutical ingredients. For cosmetics and personal care products, it is a common ingredient, serving as a humectant to prevent skin drying in hand sanitizers, a skin conditioning agent, and a base or carrier for various types of makeup. Its ability to absorb moisture and provide a smooth texture is highly valued in these formulations.

Industrial and Miscellaneous Uses: Beyond consumer-facing products, Propylene Glycol plays a crucial role in industrial applications. It is a vital chemical feedstock for producing unsaturated polyester resins, which are key components in thermoset plastics. It is also used in the creation of polyurethanes. Due to its freezing point depression properties, it is an environmentally friendly alternative to ethylene glycol in low-toxicity antifreezes, including RV and marine applications, and for aircraft de-icing fluids. Additionally, it is employed in theatrical smoke and fog machines to create safe, realistic effects for entertainment and training purposes.

Concerns about Propylene Glycol's safety are often misplaced, stemming from confusion with ethylene glycol. Propylene Glycol exhibits very low acute oral toxicity, and cases of poisoning are exceedingly rare, typically occurring only with extremely high intravenous doses in clinical settings or accidental ingestion of vast quantities. It is readily metabolized and excreted by the human body. While some individuals may experience allergic contact dermatitis when exposed topically, the overall safety profile for intended uses remains strong. Furthermore, Propylene Glycol is considered readily biodegradable in freshwater, seawater, and soil, signifying its minimal environmental impact.
