Overview
Dibutylethanolamine (CAS 102-81-8 ), also known as DBEA, is a tertiary amine alcohol used across industrial formulations as a pH regulator, corrosion inhibitor, and emulsifier.
Its combination of amine and hydroxyl functionality makes it effective in aqueous and semi-aqueous systems where both buffering capacity and surface activity are required for stability.
In metalworking and cutting fluid formulations, DBEA functions as a corrosion inhibitor and pH buffer, protecting ferrous and non-ferrous metal surfaces during machining operations.
Textile and leather processing operations use it as an emulsifier and dispersant in dyeing auxiliaries and finishing agents, improving dye uptake and surface uniformity across materials.
Water treatment programs incorporate DBEA as a neutralizing amine to control pH and inhibit corrosion in industrial cooling and boiler systems, ensuring long-term equipment protection.
In paper manufacturing, it supports sizing formulations and acts as a carrier solvent for surface treatment chemicals, enhancing the overall quality of the final paper products.
Dibutylethanolamine is supplied as a clear to pale yellow liquid in standard drum and IBC quantities. Technical grade is the primary commercial specification, with purity typically at 99% or higher.
Bulk availability supports large-volume industrial procurement in tanker quantities for continuous manufacturing operations, meeting the high demands of global chemical supply chains.
