Propylene Glycol BIO stands out as a widely used chemical raw material with a clear, odorless liquid appearance. Recognized for its good solubility in water and many organic solvents, Propylene Glycol BIO finds its place in different formulations due to its reliable characteristics and safety record. With a molecular formula C3H8O2, this compound carries a molecular weight of roughly 76.09 g/mol. Structurally, it consists of a three-carbon chain with two hydroxyl groups, boosting its water-absorbing qualities and stability. Its CAS number is 57-55-6, and the typical international HS Code used to track shipments and trade is 29053200. The material has a density close to 1.036 g/cm³ at 20°C, which provides useful information for anyone measuring volumes or planning storage.
Most Propylene Glycol BIO comes as a liquid, flowing freely at room temperature and easily mixed with many liquids and powders. Some suppliers offer it in other shapes, such as flakes, solid, powder, pearls, or crystal, each version serving a particular purpose in manufacturing or lab work. The pure liquid form stays colorless and transparent, with little to no odor, distinguishing it from more hazardous industrial chemicals. You often see it packed in drums or intermediate bulk containers, sized at 200 liters or 1,000-liter totes, making bulk transport manageable and meeting the needs of processors working at different scales. Handling solid or powdered forms, one usually appreciates the material's consistency, making it easy to measure and ship without mess.
Having worked around Propylene Glycol BIO in labs and processing facilities, one thing always stands out—its reputation for being stable and easy to handle. The substance barely vaporizes at room temperature, with a boiling point near 188°C, reducing the risk of inhalation exposure during normal handling. It stays non-corrosive and doesn't react violently with other chemicals under standard conditions, so you can store it with less worry. The material has a low freezing point (about -59°C), so it manages cold storage or winter exposure better than many other glycols. As for safety, regulatory agencies like the US FDA have approved its food-grade use, allowing it in food, personal care, and pharmaceuticals at controlled levels. Of course, despite its low acute toxicity, it shouldn't be confused with food itself. Workers should use basic personal protective equipment, such as gloves and goggles, to prevent skin and eye irritation, and should use it with good ventilation to avoid excessive buildup of vapors.
The value behind Propylene Glycol BIO comes from its blend of properties—solubility, viscosity, low toxicity, and chemical stability. In my own experience in manufacturing, I have seen this material act as a carrier in flavors and fragrances, a humectant keeping products moist, a solvent that supports pharmaceutical actives, and a coolant in food-safe antifreeze. The food, cosmetic, and pharmaceutical industries often look for high-purity versions that pass rigorous testing for contaminants. Barcodes and HS Codes on delivery containers make it straightforward for customs and quality teams to check authenticity and manage supply chain compliance. Understanding these physical and chemical details keeps suppliers and processors ahead of regulatory and reputational risks, ensuring confidence in every batch they produce or receive.
People ask about the environmental impact and safety risk. Propylene Glycol BIO breaks down easily in the environment through biological processes, so it doesn't build up like more hazardous chemicals. It’s considered less harmful to aquatic life compared to other glycols, but bulk spills still need proper containment and cleanup. Disposal teams aim to handle unwanted or expired stock through wastewater treatment facilities, not storm drains or direct discharge. Chemical labels and safety data sheets consistently note that, while not classified as hazardous under most global regulations, the material can cause mild irritation if it contacts the eyes or skin for prolonged periods. Anyone managing large stocks or planning process upgrades must account for volume, temperature, and method of application. Several companies are moving toward bio-based Propylene Glycol, produced from renewable feedstocks, which responds to calls for greener chemistry while matching the material’s usual performance standards.
In today’s market, buyers want traceable, renewable raw materials that meet quality specifications without unexpected hazards. Sourcing Propylene Glycol BIO from certified facilities using renewable biomass cuts greenhouse gas emissions and meets customer demand for transparency. I have found that investing in closed-system storage and automated metering helps keep work environments safe and minimizes wastage. Producers who disclose full technical sheets—including density, purity, physical state, and precise molecular profile—gain more trust from customers and regulators. Advances in supply chain management, such as blockchain and digital certificates, make it easier to track product origin, handling, and compliance with major regulation (like REACH, FDA, or EU food regulations). Any operation handling Propylene Glycol BIO benefits from rigorous training, up-to-date documentation, and ongoing risk assessments, a practice that keeps people informed and equipment in top shape. Responsible use and forward-looking sourcing choices can keep this versatile raw material supporting manufacturing, health, and consumer safety for years ahead, while balancing cost and environmental impact.
