Description
N-Dodecane (CAS 112-40-3, EC 203-967-9) is a straight-chain liquid paraffin hydrocarbon with the molecular formula C12H26, also known commercially as Bihexyl or Dihexyl. It carries no E-code designation and is classified under HS code 29011090 within the alkane hydrocarbons category.
In personal care formulations, N-Dodecane functions as an emulsion stabilizer and carrier solvent, improving the spreadability of active ingredients across skin and hair surfaces. In lubricants and metalworking fluids, its linear paraffin structure provides a consistent, low-viscosity lubricating film, while in coatings and adhesives it acts as a process solvent that controls viscosity during application.
N-Dodecane is supplied in technical and high-purity grades and is subject to REACH registration requirements for European market supply. Procurement quantities are typically available in drum and IBC formats. Buyers should confirm grade specification against application requirements, particularly where cosmetic or industrial lubricant standards apply.
