Description
N-Tridecane (CAS 629-50-5, EC 211-093-4, formula C13H28) is a straight-chain saturated hydrocarbon also referenced as Alkane C13, NSC 66205, and N 13. It carries no assigned E-code and is classified under HS code 29011090 within the Oils, Fats and Waxes category.
In personal care formulations, n-Tridecane functions as an emulsion stabiliser and hair conditioner by forming a hydrophobic film that reduces interfacial tension between oil and water phases. In lubricant and metalworking applications, its linear carbon chain provides a controlled viscosity base that reduces friction at metal contact surfaces without reactive residue.
N-Tridecane is supplied as a colourless liquid in standard industrial drum and IBC formats, with grades conforming to REACH registration requirements for EU market supply. Procurement teams should confirm purity specification and SDS documentation prior to order, particularly for cosmetic-grade applications requiring traceability.
