Abstract
Myristy! myristate is one of the more used waxy esters in cosmetic formulations due to its emollient properties. European legislation al!ows c\assifying as natural products to those extracted from nature sources by physical procedures or those obtained using biocatalytic methods. In this context, this work summarizes the optimization of the biocatalytic synthesis of myristyl myristate using immobilized Gandida antarctica lipase (Novozym® 435) as catalyst. This study demonstrates that operating at 70ºG, working at low pressure (be\ow atmospheric) and circulating dry N2, it is possible to obtain, in only 2 hours, an ester having the same properties (acid number and hydroxyl, iodine and saponification values) that products currently on the market. In addition, cosmetic products containing this biocatalytic myristyl myristate can be labeled as "100% natural", which is a notable commercial advantage.
