  • Applications

    7-Methylhexadecane (CAS 26730-20-1) is a branched, long-chain saturated hydrocarbon. In industrial manufacturing, it is typically used as a non-polar solvent or diluent in formulations for coatings, inks, and adhesives, and can serve as a processing aid to improve flow and handling of hydrocarbon blends. It may be used as a component in cleaning and degreasing formulations for metal parts due to its solubility characteristics. In plastics and polymer processing, it can function as a lubricant or processing aid to facilitate molding or extrusion by reducing friction between equipment surfaces. In cosmetics and personal care, it may be employed as a non-polar carrier or solvent for formulations where a light hydrocarbon material is appropriate.
