1-hexadecene
Description
1-Hexadecene (CAS 629-73-2), also known commercially as cetylene, is a long-chain linear alpha olefin used as a reactive building block and functional ingredient across polymer, lubricant, and personal care manufacturing.
Its terminal double bond makes it a preferred monomer and co-monomer for controlled chemical reactions in industrial synthesis. In plastics and polymer production, it serves as a co-monomer in polyethylene and polyalphaolefin synthesis.
This chemical influences chain branching and final resin properties to meet specific performance targets. Lubricant formulators use it as a feedstock for synthetic base oils and viscosity modifiers for automotive and industrial fluids.
Controlled oligomerization delivers tailored lubrication profiles for high-performance applications. In personal care, it functions as an emollient carrier and dispersing agent in skin-feel formulations, contributing to spreadability and texture.
It is frequently utilized in creams and serums to enhance the user experience. It also acts as a plasticizer and softening agent in specialty coatings and adhesive systems requiring flexible film formation during the curing process.
The product is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for high-volume industrial buyers. Standard commercial grades are available at purities of 95% and 98%+.
High-purity polymer-grade specifications are offered for co-monomer applications. Our logistics network ensures reliable delivery of this essential olefin to manufacturing facilities worldwide while maintaining strict quality control protocols.
