2-[(Docosyloxy)methyl]oxirane is a long-chain alkyl glycidyl ether containing a C22 hydrophobic alkyl chain and an epoxy functional group. It is mainly used as a reactive surfactant intermediate, epoxy modifier, chemical intermediate for specialty polymers, coatings, adhesives, and sealants. It can improve flexibility, hydrophobicity, chemical resistance, and processing properties of polymer materials.
