  • Applications

    3-Methyltetracosane (CAS 65820-52-2) is a high-molecular-weight branched alkane that is typically used as a nonpolar hydrocarbon component in lubricant basestocks and greases; it can serve as a waxy additive in coatings, inks, and adhesives to adjust hardness and film-forming properties; it may act as a processing aid or diluent in polymer and plastics formulations to assist mixing and flow; it can be found as a waxy constituent in paraffin wax blends used for candles and household products; and in cosmetic/personal care applications it may contribute as a waxy thickener or texture modifier in certain formulations, subject to local regulations and formulation limits.
