Product Description
What Is Isopropyl Palmitate?
An ester called isopropyl palmitate is made from isopropyl alcohol (C3H7OH) and palmitic acid (C16H32O2). It is a colorless, transparent liquid that is frequently used in medications, healthcare items, and cosmetics due to its emollient, solvent, and skin penetration-enhancing qualities. It contributes to the smooth, non-greasy feel of formulations by improving their texture and spreadability. Additionally, isopropyl palmitate finds use in industry as a solvent and lubricant.
Preparation involves an esterification reaction between palmitic acid and isopropyl alcohol, typically using an acid or base catalyst. The reaction is carried out at elevated temperatures (100-150°C), with water being removed to drive the reaction to completion. Following the reaction, either distillation or filtration is used to purify the result.
