Description
1-Hexadecene (CAS 629-73-2), also known commercially as cetene or 1-cetene, is a straight-chain terminal alkene with the molecular formula C16H32. It carries no assigned E-code and is classified under HS code 29012990 for customs purposes.
In personal care formulations, 1-hexadecene functions as an emollient and hair conditioner by forming a thin, occlusive film on skin and hair surfaces that reduces moisture loss. In lubricant and polymer manufacturing, it serves as a reactive comonomer and chain modifier, improving flexibility and reducing friction coefficients in finished products.
1-Hexadecene is supplied in technical and high-purity grades and falls under REACH registration requirements for EU market access. Procurement quantities are available in standard drum and IBC formats. Buyers should confirm grade specification against application requirements, particularly for cosmetic-grade use where purity thresholds apply.
