Sebacic acid, identified by its CAS number 111-20-6, is a C10 linear saturated dicarboxylic acid derived from castor oil, a renewable resource. Its molecular structure, featuring two terminal carboxyl groups, grants it exceptional reactivity and versatility, making it a vital intermediate in numerous industrial sectors. As a leading manufacturer and supplier, we highlight the diverse applications of this crucial organic chemical.

Plasticizers: One of the most significant uses of sebacic acid is in the production of sebacate esters, such as dibutyl sebacate (DBS) and dioctyl sebacate (DOS). These esters function as high-performance plasticizers, imparting superior flexibility, low-temperature performance, and excellent resistance to extraction in polymers like PVC, synthetic rubbers, and cellulose acetate butyrate. Buyers seeking to enhance the pliability and durability of their plastic products often turn to sebacic acid for its ester derivatives.

Lubricants and Greases: Sebacic acid is a key ingredient in the synthesis of synthetic lubricating oils and their additives. The esters derived from sebacic acid offer excellent thermal and oxidative stability, high viscosity indexes, and good low-temperature properties. These characteristics are essential for lubricants used in high-stress environments, such as automotive engines, aviation hydraulics, and industrial machinery. As a reliable sebacic acid supplier, we support the production of high-quality lubricants.

Polyamides (Nylon): Sebacic acid is a critical monomer for the production of specialty polyamides, notably nylon 1010, nylon 910, and nylon 610. These nylons exhibit enhanced properties such as improved dimensional stability, lower moisture absorption, and greater flexibility compared to conventional nylons. They are used in demanding applications including automotive fuel lines, electrical insulation, and industrial filaments. Sourcing high-purity sebacic acid is key for successful nylon synthesis.

Cosmetics and Coatings: In the cosmetics industry, sebacic acid derivatives act as emollients, solvents, and conditioning agents, contributing to the texture and feel of skincare and makeup products. In the coatings sector, sebacic acid is used to produce alkyd resins, which form the basis of many durable and high-performance paints and varnishes. Its ability to react with polyols makes it valuable for creating resins with specific properties.
