Cetyl palmitate was synthetized by esterification the cetyl alcohol with palmitic acid in a solvent-free system.
Reactions were performed in batch mode using commercial lipase Lipozyme RM IM as catalyst.
Stirring speed (180, 480 and 720 rpm), temperature (60, 70, 80 and 87 °C), amount of catalyst (0.5, 1.0 and 1.5% wt% related to the mass of substrates) and alcohol:acid molar ratio (0.5:1, 1:1 and 2:1) were evaluated and best reaction conditions obtained were 480 rpm, 70 °C, 1.0% of enzyme and 1:1 M ratio.
A novel kinetic model based on random-sequential bi-bi mechanism was proposed and showed a good agreement with experimental data.
Furthermore, this model was proved to be suitable for kinetics predictions with a small uncertainty.
The catalyst was recycled and showed good stability since reaction conversion decreased only 6.8% after 15 reuses.

The Palmitates used in cosmetic products are esters of palmitic acid and octyl, cetyl, or isopropyl alcohol.
Cetyl palmitate was produced by the esterification of palmitic acid with cetyl alcohol using n-hexane as solvent and a fermented solid of Burkholderia contaminans as catalyst.
Effects of temperature (35–55 °C) and alcohol:acid molar ratio (0.5:1–2:1) on the reaction kinetics were evaluated for a fixed amount of catalyst (10 wt% related to the total mass of substrates) and a stirring speed (600 rpm) that was sufficiently high to avoid convective mass transfer limitations in the bulk phase.
