Didecyl Adipate stands as a clear, pale yellow, oily liquid with a faint odor, recognized for its significant role in the world of industrial chemicals. Its structure falls within the family of dialkyl adipates, shaped by the esterification of adipic acid and decyl alcohol. You’ll find the molecular formula as C26H50O4 and a molecular weight holding steady at about 426.68 g/mol. Didecyl Adipate goes by the HS Code 29171300, placing it among organic acids and their derivatives for global trade. Liquid under room conditions, it resists the formation of crystals or flakes. It never turns up as a powder or pearl; this remains a principal trait that distinguishes it from other adipates or common plasticizers.
Its density hovers around 0.92 g/cm3 at 20°C, floating lighter than water. Didecyl Adipate does not freeze into a solid at typical storage temperatures but enters a glassy phase near -35°C. Viscosity marks the material as smooth-flowing — around 9–12 mPa.s at 20°C. It refuses to dissolve in water, though it marries well with organic solvents like ethanol, mineral oils, and most hydrocarbons. The molecular bond structure shows long chain decyl groups on either side of the adipate backbone, giving flexibility and a low pour point to finished products. This is the same backbone that grants the compound low volatility and better spreadability than shorter ester cousins.
Didecyl Adipate enters conversations about efficient plasticizers mostly in PVC (polyvinyl chloride), where softness and resistance to cold temperatures matter. Its impact goes beyond plastics — you might find it softening the edge on synthetic rubbers, improving flow in lubricants and greases, and even smoothing the ride in cosmetic applications where skin contact safety rates highly. Its raw materials, adipic acid and decyl alcohol, rank as reliable, cost-effective feedstocks, often allowing manufacturers to respond to rising demand without significant supply crunches. Many companies add Didecyl Adipate for that unique balance of low temperature flexibility and general plasticizer efficiency.
Didecyl Adipate gets inspected on color (APHA value below 100), acid value (below 0.2 mg KOH/g), and saponification value (around 270–290 mg KOH/g). Water content rarely reaches above 0.1%. This ensures it fits right into sensitive use cases like medical plastics, toys, or automotive interiors. Volume is usually measured in liters, while quality checks run per batch or drum. Material handling best practices recommend using steel or HDPE containers. I've seen that clear labeling of “Didecyl Adipate, HS Code 29171300” keeps customs and regulatory audits clean.
Didecyl Adipate registers low acute toxicity both by oral and skin exposure. No immediate hazardous or harmful effects pop up in standard workplace settings, though routine use of gloves and goggles remains good practice in case of splashing or prolonged handling. It does not count among substances linked with cancer, genetic damage, or reproductive effects. If spills happen, cleanup with absorbent material and proper disposal by chemical waste routes limits environmental exposure. Aquatic toxicity sits in the moderate range; responsible companies often implement controls to keep it from major waterways. No one likes fielding questions about long-term ecological buildup, so regular environmental audits show good faith and care over time.
Experience in materials purchasing or process engineering teaches that understanding physical characteristics and reliable specifications allows smoother operations and less friction with regulators. Chemical buyers want clarity on density, phase, and handling to compare among different plasticizer choices. Factory workers rely on safety information to avoid health incidents, especially if batches shift in quality. Communicating accurate details — not just a list of properties — builds trust with partners up and down the supply chain. Tracking Didecyl Adipate’s HS Code, full molecular formula, and key safety info simplifies everything from contract negotiation to reporting for compliance or tax authorities.
Improving the safe, efficient use of Didecyl Adipate starts with better information sharing. Chemists and supply managers should post current specs, safety data, and supplier certifications for all staff. Regular training in spill control and personal protection gear goes a long way, reducing accidents. Manufacturers can push for raw materials derived from green sources (renewable adipic acid, biobased decyl alcohol) to bring down environmental impact. Integrating digital traceability tools, like QR codes linking to certification documents and batch analysis, closes gaps for transparent trade. Policy makers and industry groups may encourage research on safer, more biodegradable alternatives, but until then, clear standards for Didecyl Adipate keep workplaces running, products compliant, and communities protected.
