  • Applications

    1-Hexacosene (CAS 64808-91-9) is a long-chain alpha-olefin that serves as a versatile building block in several industrial applications. It is commonly used as a feedstock for hydroformylation (oxo process) to produce long-chain fatty alcohols and aldehydes, which are then used in the manufacture of surfactants and detergent formulations. It can be evaluated as a comonomer in polyolefin production to tailor polymer properties such as processing behavior and density. It serves as a precursor for synthetic hydrocarbon lubricants and waxes, including polyalphaolefins, for high-temperature or specialty lubrication and for producing waxes used in coatings and release agents. It may be oxidized or functionalized to long-chain acids or alcohols that find use in household cleaning products and other specialty formulations. Additionally, it can act as a wax-like processing aid or slip agent in coatings, inks, and adhesive formulations to improve texture and handling. Subject to local regulations and formulation limits.
