1-Docosanol

1-Docosanol (CAS 1599-67-3) is a long-chain fatty alcohol also known commercially as Docosene, Jarcol 22, and NSC 78486. It carries no assigned E-code and is classified under HS code 2901290000 as an acyclic unsaturated hydrocarbon building block.

In plastics and polymer manufacturing, 1-docosanol functions as a polymerization initiator and chain-length regulator, influencing molecular weight distribution in the final resin. In personal care formulations it acts as a plasticizer and softener, modifying texture and film flexibility. Its long carbon chain also provides boundary lubrication in metalworking fluids, reducing surface friction under load.

1-Docosanol is supplied as a solid and is available in technical and cosmetic-grade specifications. It falls under REACH registration requirements for EU procurement. Buyers should confirm grade suitability against relevant pharmacopoeial or industry standards; packaging formats vary by supplier and should be confirmed at the time of order.
