Propylene Glycol Selection for Aircraft Deicing Fluid Applications, identified by its CAS number, plays a crucial role as a reagent in the specialized production of deicing fluids used in aviation environments. Its molecular formula allows for tailored performance under aviation industry requirements, while the molecular weight contributes to optimized fluidity and efficacy during application. For precise sourcing and compliance purposes, the IUPAC name and InChIKey provide an unambiguous route to substance identification and traceability throughout the supply chain.
Propylene glycol intended for aircraft deicing demonstrates a set of physical and chemical properties specifically aligned with operational needs in cold environments. Its boiling point ensures effective vapor management and reduces loss during storage or application, while the melting point supports reliable performance in below-freezing conditions. The density of the material is considered when formulating deicing fluids to maintain proper spreadability and contact time on aircraft surfaces. Additionally, the flash point is a safety-critical parameter, informing safe handling and application under a range of climatic scenarios. Vapor pressure data, where available, assist in risk assessment and vapor containment strategies for ground crews.
From a regulatory and compliance perspective, propylene glycol for this application meets stringent European REACH registration requirements, which detail both the applicable article numbers and relevant tonnage bands governing its import, use, and handling in the EU region. On the United States side, its inclusion in the TSCA inventory is supported by direct reference to the active section, affirming its ongoing legal status. Internationally Harmonized Classification and Labeling (GHS) designations are clearly outlined, including all specific H-phrases that address its hazard profile, and the required signal word for rapid hazard communication. Occupational exposure considerations are covered by OSHA’s Permissible Exposure Limit (PEL) and any corresponding NIOSH Recommended Exposure Limit (REL), where noted. Furthermore, pharmacopoeial citations, when present, guide its suitability and expected purity within regulated formulation spaces.
As a reagent, propylene glycol’s applications extend beyond deicing into other industrial and pharmaceutical manufacturing processes. However, in the context of aviation, its role remains narrowly focused on enabling the effective synthesis of glycols that compose the backbone of deicing and anti-icing fluids. This activity is supported by established PubChem use indices, although it is important to note that this compound is not employed for therapeutic efficacy, but rather for its functional properties in large-scale chemical blends used to ensure the safety and operational continuity of aircraft in freezing conditions.
The chemical is typically dispatched in robust packaging options aligned with international logistics and safety norms, including 25 kg drums for smaller operations, 200 kg drums for mid-scale use, and intermediate bulk containers capable of accommodating larger supply needs. Storage recommendations, drawn from GHS stability data, call for propylene glycol to be stored in a cool, dry, and well-ventilated location, away from incompatible substances and potential ignition sources. Shelf life expectations correspond with those broadly accepted for this class of glycols, which provides both suppliers and end users with predictable product quality timelines for optimal utilization.
