Polypropylene glycol (17) butyl ether stands as a versatile liquid material used across a range of chemical applications. Identified by its unique structure, this compound, with the molecular formula C23H48O10, balances the characteristics of a polyether backbone with a terminal butyl group. Typically found as a nearly colorless, slightly viscous liquid, it features mild odor and solid performance properties that matter to chemists, handlers, and formulators alike. Polypropylene glycol (17) butyl ether brings together solubility, stability, and efficient surface activity, making it functional in industrial formulations, coatings, special finishes, and lubricants.
This ether consists of about 17 propylene oxide repeating units linked to a single butyl group, forming a long chain structure that influences both its chemical and physical behavior. The material's relatively high molecular weight provides it with unique viscosity and flow characteristics, making it especially attractive as a raw material in polymer science. Users can count on it for consistent molecular structure, resulting in predictable outcomes in blending and processing. The ether group imparts hydrophobic qualities, which improves compatibility with many organic solvents, while the polyol section ensures good wetting and plasticizing capabilities. This balance between hydrophobic ether and hydrophilic polyol drives its performance in scenarios demanding controlled solubility and flow.
Polypropylene glycol (17) butyl ether is generally available in liquid form, usually delivered by liter or drum. The density commonly ranges between 1.00 and 1.05 g/cm3 at room temperature, depending on the exact distribution of molecular weights present. Its appearance may shift slightly between clear and pale yellow liquid, meeting the high standards for clarity required in many end uses. Unlike polyethylene glycols, this polyether tends to resist crystallization, so it does not present as a solid, powder, flakes, pearls, or crystals under standard conditions; it maintains its liquid state across a wide temperature range.
Demand for polypropylene glycol (17) butyl ether continues in fields that require a stable, low-volatility solvent or plasticizer. As a raw material, it gets included in specialty lubricants, hydraulic fluids, and coolants. Industrial formulators appreciate its impact on viscosity, giving them more precise control in finished product flow rates and stability. In coatings and inks, this ether enables smoother application and can help disperse other solid or liquid additives. It also fits into some cleaning products, thanks to its ability to dissolve both polar and nonpolar contaminants efficiently. Its balanced molecular structure pushes it into various solution-based environments where controlled solvency is needed for peak material performance.
With its clear molecular identity, polypropylene glycol (17) butyl ether claims a stable place in chemical supply chains. It carries low volatility, limiting inhalation exposure during use. Safety always takes top priority with chemicals, and while this ether generally ranks as low hazard, good practice means avoiding direct contact with eyes or skin and ensuring appropriate ventilation during handling. SDS sheets and chemical guides stress the importance of gloves and eye protection. Water solubility is limited, but it resists rapid breakdown in ambient conditions, so spills should be contained and cleaned quickly. Flammability stays low compared to lower molecular weight ethers, yet storage guidelines recommend cool, dry environments away from oxidizers or sources of ignition.
Polypropylene glycol (17) butyl ether features the Harmonized System Code (HS Code) 29094990 under international trade classifications, situating it alongside other polyether alcohols and derivatives. Customs processes use this code to track shipments and assess duties. Supply chain professionals use the HS Code to source, sell, and declare this raw material globally, adding clarity and predictability to business operations. Regulatory compliance for import and use depends on national legislation; in most jurisdictions, this polyether’s registration covers standard chemical use, with attention placed on industrial rather than consumer applications.
Every raw material invites questions about harm and impact. Polypropylene glycol (17) butyl ether, though safer than many solvents and glycols, still deserves respect. Whether poured by the liter in a factory or measured for a laboratory mix, exposure controls make a difference. The substance rarely falls on hazardous or restricted lists, but sizable spills could cause local aquatic harm due to biological resistance. Waste management means collecting and disposing of residues following environmental rules for organic compounds. Any new chemical in the plant or lab calls for training, spill response kits, and regular review of storage tanks and lines to prevent leaks or accidental release. Manufacturers and users share responsibility for keeping workspaces safe and reducing environmental risk.
The backbone of polypropylene glycol (17) butyl ether production comes from propylene oxide and butyl alcohol, both established industrial intermediates. Secure and consistent raw material flow keeps costs predictable and builds resilience against market shocks. Chemical plants convert propylene oxide into polyether chains under controlled conditions, then cap these chains with butyl groups, producing this specialty ether in batch or continuous systems. Producers invest in purification and quality assurance so customers receive product with reliable molecular profiles and physical properties. Supply chain teams track liter shipments and bulk orders across continents, supporting sectors that depend on on-time delivery and uncompromised quality.
