1,2-Decanediol comes from a line of chemical compounds called alkanediols, where two hydroxyl groups attach to a ten-carbon straight chain. Chemists know it for its molecular formula C10H22O2, and its structure turns out to be pretty straightforward—a decane backbone with OH groups on the first and second carbons. This setup gives it a blend of oily feel with a bit of stickiness due to hydrogen bonding. HS Code for 1,2-Decanediol generally falls under 2905399000, classifying it as an organic chemical under the alcohols category, which matters for shipping and customs paperwork.
In its solid form, 1,2-Decanediol appears as white flakes, powder, crystals, or sometimes pearls. These forms feel waxy to the touch, kind of like a fusion of paraffin with a dash of smoothness, and they melt when exposed to gentle heat, turning into a clear and slightly viscous liquid. Liquid 1,2-Decanediol holds its own as a material—clear, colorless, almost odorless. Its melting point falls between 36–39°C. That means it may arrive as a solid or viscous liquid depending on room conditions. Solubility stays limited in water but it mixes well with hot alcohol or other glycols, which turns useful in formulations involving solvents or personal care products.
With a molecular weight of about 174.28 g/mol, 1,2-Decanediol shows a density around 0.91 g/cm3 in its liquid state. The molecule packs ten carbons into a straight line, and both hydroxyl groups hang out just one bond apart—this feature creates a bit of polarity, though the long carbon chain gives most of the mass a non-polar nature. Because of this setup, it doesn’t dissolve much in water yet mixes well with organic solvents—something that’s a lifesaver in the lab for formulating emulsions or ointments.
People in the chemical and cosmetic industries work with 1,2-Decanediol for its mild antimicrobial effect and its slick texturizing power, which means it can keep formulas stable without adding greasy residue. Going from this basic science to product shelf takes some care: proper storage avoids moisture exposure since hygroscopicity can bring trouble with clumping. When handling industrial quantities, engineers check material safety data sheets for hazards—1,2-Decanediol does not rank as acutely hazardous, but direct contact can lead to mild skin or eye irritation. Good practice involves gloves and goggles, making accidents less likely, and using ventilation or masks if powders or dust get airborne.
Raw 1,2-Decanediol steps into many roles. In skincare, it fights off bacteria without the sting of harsher agents, supporting preservative systems in creams, shampoos, and lotions. As a solvent, it keeps formulas smooth and stable. Industrial settings use it as a building block, mixing it into more complex esters, lubricants, or surfactants. A challenge people mention centers on inconsistent flake or powder size in shipments, which affects dosing. Consistent sieving and dry storage in airtight containers solve most of these problems before they reach the user.
Even though classification does not mark 1,2-Decanediol as broadly hazardous, regular users should treat it with the respect any raw chemical deserves. Spills bring slippery surfaces; inhaling dust can irritate the lungs if not ventilated. Companies that move and process it bulk up with spill kits and keep MSDS sheets on hand. The HS Code and relevant regulatory paperwork must follow shipments across borders, and accurate labeling ensures it doesn’t get mixed up with similar diols. Companies serious about workplace safety will check for changes in regulations or new toxicology updates just as a part of ongoing safety programs.
1,2-Decanediol gives chemists and product developers a sturdy platform—ten carbons long, with dial functionality for building new molecules or enhancing well-tested products. The density and melting range hit that sweet spot between flexible application and shelf stability. Its antimicrobial effect gives formulators a mild, not-overpowering asset, and being low-toxicity compared to other actives, it gives end users peace of mind without sacrificing performance. Supply chains value the stable price and straightforward HS Code classification, while businesses enjoy smooth customs clearance with the base paperwork.
Over the years, chemists and product folks track the evolution of personal care ingredients—trends shift, but demand for reliable raw materials like 1,2-Decanediol doesn’t dip. In my experience, problems don’t start in the lab—they start in the warehouse, at shipment, or when end users try working with clumpy solids. Manufacturers that stay ahead with batch testing, humidity control, and honest labeling build longer-lasting trust. Whenever a new ingredient gets hot in trend cycles, it pays to look deeper at origins, safety, and performance under real-world use, not just in idealized tests. Knowing the specs, density, physical forms, and handling tips for 1,2-Decanediol takes some pressure off everyone from compliance teams to shelf-stockers.
