Description
Lauryl methacrylate (CAS 142-90-5), also known as LAMA, dodecyl methacrylate, Rocryl 320, and Sipomer LMA, is a long-chain alkyl methacrylate monomer with the molecular formula C16H30O2. It carries no assigned E-code and is classified under HS code 29161490 for customs purposes.
In polymer synthesis, LAMA is incorporated into acrylic copolymers to introduce flexible, hydrophobic chain segments that lower glass transition temperature and improve film flexibility. In lubricant formulations, its polymerized form acts as a viscosity index improver, reducing viscosity variation across temperature ranges. Personal care chemists use it as a film-forming monomer in hair conditioning and styling polymers.
Lauryl methacrylate is supplied as a stabilized liquid grade and is subject to REACH registration requirements within the EU. Procurement teams should confirm inhibitor content and storage conditions when specifying grades. Standard packaging includes drums and IBC containers, with documentation available to support REACH compliance obligations.
