Understanding the precise chemical characteristics of raw materials is fundamental for any formulator or procurement specialist aiming for optimal product development and consistent quality. Diisopropyl Sebacate, known by its CAS number 7491-02-3, is a chemical compound whose properties have made it indispensable in various industries, particularly cosmetics and fragrances. This article delves into the detailed chemical profile of Diisopropyl Sebacate, providing essential information for professionals seeking to source and utilize this ester effectively.

At its core, Diisopropyl Sebacate is a diester formed from the reaction of sebacic acid (a dicarboxylic acid) and isopropanol (an alcohol). This esterification process results in a molecule with the molecular formula C16H30O4. With a molecular weight of approximately 286.41 g/mol, DIPS presents as a relatively stable compound under standard conditions. Its IUPAC name is dipropan-2-yl decanedioate, and common synonyms include Sebacic acid, diisopropyl ester, and Dermol DIPS, among others listed in chemical databases.

Key physical and chemical properties of Diisopropyl Sebacate are critical for its application. It is typically described as a clear, colorless liquid with a low odor, often perceived as faintly fruity. Its boiling point is reported around 308.2°C at standard atmospheric pressure, indicating its low volatility. The flash point, an important safety parameter, is approximately 134.9°C, classifying it as a combustible liquid. Its density is around 0.953 g/cm³, and its refractive index is typically measured at 1.443. These physical attributes contribute to its ease of handling and incorporation into formulations.

For formulators, understanding its solubility is also key. Diisopropyl Sebacate is generally soluble in organic solvents and oils, which aligns with its use as an emollient and a carrier for fragrances. Its solubility in water is very low, a characteristic that contributes to its skin-conditioning and moisturizing effects by helping to reduce water loss from the skin.

When sourcing Diisopropyl Sebacate, professionals will often look for suppliers who provide these detailed specifications. Ensuring a high purity level, typically 99% or more, is crucial for applications where purity dictates performance, such as in high-end cosmetics or sensitive fragrance blends. For procurement managers, being able to access a comprehensive Certificate of Analysis (CoA) from a trusted Diisopropyl Sebacate manufacturer is paramount. This document verifies the product's adherence to specified standards, including purity, acid value, and water content.

For those looking to buy Diisopropyl Sebacate, understanding its chemical profile ensures that you are selecting the correct grade for your specific needs. Whether for its emollient qualities in skincare, its solvent capabilities in fragrances, or its potential use in industrial applications like plasticizers, precise chemical data is the foundation of informed purchasing decisions. Partnering with a reputable chemical supplier that provides accurate and detailed product information is essential for success.

In conclusion, Diisopropyl Sebacate (CAS 7491-02-3) is a well-defined chemical compound with a valuable set of properties. A thorough understanding of its molecular structure, physical characteristics, and typical specifications, as provided by reliable manufacturers, empowers formulators and procurement specialists to make informed choices when sourcing this ester. If you require this ingredient, consider exploring offerings from established suppliers to ensure quality and performance.
