For chemists, formulators, and researchers, a thorough understanding of chemical ingredients is fundamental to innovation. Isopropyl Palmitate (IPP), known by its CAS number 142-91-6, is a ester that warrants detailed examination due to its widespread application across various industries. This article aims to provide a comprehensive overview of its chemical characteristics and functional benefits.

Chemically, Isopropyl Palmitate is the isopropyl ester of palmitic acid, a saturated fatty acid. This esterification process results in a compound with a distinct set of physical and chemical properties. It presents as a clear, colorless to pale yellow oily liquid with a low viscosity. Its molecular formula is C19H38O2, and it possesses a molecular weight of approximately 298.51 g/mol. Key specifications often include a purity of ≥98%, an acid value typically less than 0.3 mg KOH/g, and a flash point indicative of its stability.

One of the most significant attributes of Isopropyl Palmitate is its performance as an emollient and moisturizer. It creates a protective barrier on the skin, reducing transepidermal water loss and maintaining hydration. Unlike many heavier oils, IPP is known for its non-greasy feel and excellent spreadability, allowing formulations to be easily applied and absorbed without leaving a sticky residue. This makes it a preferred ingredient in cosmetic lotions, creams, and serums.

In the pharmaceutical sector, Isopropyl Palmitate serves as a valuable excipient. It functions as a solvent for lipophilic drugs, aiding in their formulation and enhancing their percutaneous absorption. Its role as a penetration enhancer is critical for the efficacy of transdermal drug delivery systems. For those seeking to purchase Isopropyl Palmitate for research or production, identifying a reliable supplier who provides detailed technical data sheets and Certificates of Analysis is essential.

The versatility of Isopropyl Palmitate is further demonstrated by its use in other applications, including as a thickening agent, an anti-static agent, and a solvent for fragrances. Its compatibility with a wide range of other chemical compounds makes it an adaptable ingredient for diverse formulations.
