Sebacic Acid
30,000 TPAThe bio-based building block for green nylons and beyond.
Sebacic Acid
Overview
A premium-grade, bio-based dicarboxylic acid derived from castor oil. Sebacic Acid is the core product of Sebacic Oman's biorefinery — a clean, high-purity substitute for petroleum-derived intermediates used across polymers, cosmetics, lubricants, and corrosion protection.

Applications
Bio-Nylons (PA 6.10 / 4.10 / 10.10)
Sebacic Acid is the C10 diacid monomer in polyamide 6.10, 4.10, and 10.10 — high-performance bio-based nylons used in automotive fuel lines, sporting goods, and engineering plastics. These polymers are non-carcinogenic replacements for conventional petroleum-based nylons.
Cosmetics & Skincare
Widely used as a pH corrector, mild exfoliant, SPF booster synergist, and skin-conditioning emollient in premium skincare formulations. Safe, biodegradable, and effective across a broad pH range.
High-Performance Lubricants
Esters of sebacic acid (e.g., dioctyl sebacate) are key base-fluid components in aircraft engine lubricants, automotive transmission fluids, and industrial gear oils — valued for their thermal stability and low pour points.
Engine Coolants
Sebacate salts are standard corrosion inhibitors in OAT (Organic Acid Technology) coolants used in automotive and aerospace cooling systems, providing long-drain, metal-protection performance.
Anti-Corrosion Coatings
Used as a corrosion inhibitor and crosslinker in industrial coatings and metal-working fluids, providing durable protection for ferrous and non-ferrous substrates.
Plasticizers
Sebacic acid esters serve as primary and secondary plasticizers in PVC and specialty polymer applications requiring low-temperature flexibility.
