Diethyl sebacate

Diethyl sebacate (CAS 110-40-7), commonly abbreviated as DES, is an ester of sebacic acid used across lubrication, plastics, flavoring, and cosmetic formulations. FEMA 2376 recognition positions it as a regulated flavoring ingredient in food applications. Its low volatility and compatibility with a broad range of substrates make it a functional choice across both industrial and consumer-grade products. In lubricant and metalworking fluids, DES functions as a synthetic base fluid or co-fluid.

This material offers thermal stability in high-performance formulations. Polymer and plastics manufacturers use it as a plasticizer to improve flexibility and processing characteristics in resins and coatings for various industrial uses. In flavor systems, it contributes fruity, fatty notes to food and beverage products under its established regulatory approval. Personal care formulators incorporate DES as an emollient and moisturizing agent in skin creams.

It is also frequently utilized in hair conditioners and cosmetic serums to enhance texture. Diethyl sebacate is supplied as a clear, low-viscosity liquid in drums, IBCs, and bulk quantities for large-scale manufacturing. It is available in food-grade and technical-grade specifications to meet the distinct purity requirements of flavor, cosmetic, and industrial applications. Cosmetic and food-grade material is typically evaluated against FCC standards.
