A Green, Solvent-free Biocatalytic Method to Produce Cosmetic Esters
By: Neil W. Boaz, PhD, and Stephanie K. Clendennen…
Cosmetic esters can be produced effectively via a solvent-free, biocatalytic method. This green process, described by the authors, involves combining two reactants and an enzyme, and is driven to high conversion by the removal of by-products through a nitrogen purge—in turn producing high purity materials directly from the reactor.
