  • Isopropyl palmitate is an fatty acid ester. Isopropyl palmitate can be used for design and characterization of bioactive bilayer films. The bilayer membrane not only has the ability to scavenge free radicals and inhibit lipid peroxidation, but also can inhibit the growth of known foodborne pathogens. Isopropyl palmitate can be used as an excipient, such as lubricant, oily carrier, solvent, controlled-release transdermal film. Pharmaceutical excipients, or pharmaceutical auxiliaries, refer to other chemical substances used in the pharmaceutical process other than pharmaceutical ingredients. Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations, which can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism, and elimination (ADME) processes of co-administered drugs[1][2].
