Diisopropyl Sebacate丨CAS 7491-02-3

Diisopropyl sebacate is a versatile diester widely used in cosmetics, pharmaceuticals, polymer chemistry, and industrial formulations. In personal care and cosmetic products, it functions as an emollient, skin-conditioning agent, and solvent for fragrances, improving texture, spreadability, and sensory feel. In pharmaceutical formulations, it is applied as a solubilizer for lipophilic drugs, a plasticizer in topical or transdermal delivery systems, and a medium for controlled-release formulations. In polymer and material science, diisopropyl sebacate serves as a plasticizer for elastomers, coatings, and resins, enhancing flexibility, durability, and mechanical performance. It is also used in lubricant formulations, chemical intermediates, and as a carrier solvent in fine chemical synthesis, demonstrating versatility across multiple industrial sectors.

The benefits of diisopropyl sebacate arise from its low viscosity, high solvency, and biocompatibility. It exhibits excellent compatibility with oils, waxes, polymers, and cosmetic bases, providing smooth texture and enhancing spreadability. Its chemical stability under normal storage conditions and thermal resilience make it suitable for high-performance applications in polymers and coatings. The diester structure ensures low volatility, good skin absorption, and minimal irritation in cosmetic and pharmaceutical formulations. Additionally, it acts as an effective plasticizer, improving flexibility and reducing brittleness in elastomeric and polymer systems. Its clear liquid form, solubility, and inert nature support ease of formulation and reproducibility in industrial and laboratory processes.
