Isododecane

Isododecane (CAS 31807-55-3, EC 250-816-8) is a branched C12 isoparaffin hydrocarbon solvent, commercially available under trade names including Fancol ID, Hyfrane 120, Marukasol R, Purolan IDD, and Permethyl 99. It carries no E-code designation and is categorised within the aliphatic hydrocarbon solvent class.

In personal care formulation, isododecane functions as a volatile carrier that evaporates cleanly from skin, leaving no residue, making it a standard solvent in long-wear foundations, mascaras, and sunscreen films. In lubricants and metalworking fluids, its low surface tension and chemical inertness support dispersion of active additives and reduce friction at metal interfaces.

Isododecane is supplied as a liquid and is subject to REACH registration requirements within the EU. Procurement teams should confirm supplier compliance documentation, including Safety Data Sheets aligned with Regulation (EC) No 1907/2006. Packaging formats typically include drums and IBC containers depending on volume requirements.
