2-Methylundecane

2-Methylundecane, commonly known as isododecane or 2-methylhendecane, is a branched-chain saturated hydrocarbon with the molecular formula C12H26, registered under CAS 7045-71-8 and EC 230-323-4. It carries no E-code designation and is commercially available in practical grades at approximately 85% purity.

In personal care formulations, isododecane functions as a lightweight carrier solvent that dissolves silicones, pigments, and film-forming polymers while leaving minimal residue on skin. In metalworking and lubricant applications, its branched structure reduces viscosity and improves spreadability across metal surfaces. Printing ink formulators use it to control drying rate and pigment dispersion stability.

2-Methylundecane is supplied as a liquid oil-phase material and falls under REACH registration requirements for EU market supply. Procurement teams should confirm supplier documentation including Safety Data Sheets and certificates of analysis specifying purity grade. Packaging formats typically follow standard industrial solvent conventions including drums and intermediate bulk containers.
