Isopropyl palmitate and isopropyl myristate are both esters of isopropanol, but they differ in the fatty acids that they contain. Isopropyl palmitate contains 16 carbons in the chain while isopropyl myristate has 14 carbons. Because of this difference, isopropyl palmitate is more greasy to the touch than isopropyl myristate. In addition, isopropyl myristate is more readily absorbed by the skin.
