Chemistry, Properties & Perfumer Guide

The Chemistry

Lauryl methacrylate is an ester of methacrylic acid and lauryl alcohol, belonging to the acrylate ester family. It polymerizes readily to form polymethacrylates. The compound is produced industrially through esterification reactions between methacrylic acid derivatives and lauryl alcohol, typically using acid catalysts. Its primary use is in creating hydrophobic polymers with specific mechanical properties.
