Diethanolamine

Diethanolamine (DEA) is a secondary ethanolamine widely used in detergents, corrosion inhibitors, metalworking fluids and gas treatment applications. As a China Diethanolamine supplier, Dotachem provides DEA 99.3% with controlled key specifications, packaging options and export shipment support.

Product Introduction of Diethanolamine


Diethanolamine contains both amine and hydroxyl functional groups, which makes it useful in surfactant production, acid gas treatment, metalworking fluids, detergents and cleaning formulations. In many applications, DEA helps support alkalinity control, emulsification, corrosion inhibition and formulation stability.


Key indicators such as purity, color, water content, density and batch consistency may affect downstream processing and formulation performance. Dotachem supplies DEA 99.3% with controlled specifications, flexible packaging options, order planning support and export shipment coordination for regular purchasing requirements.

Key Features of Diethanolamine


 - Stable DEA Content for Industrial Formulations


Dotachem supplies Diethanolamine with DEA content of ≥99.3%, helping customers maintain more stable formulation performance in regular production. For manufacturers using DEA as a raw material or intermediate, consistent quality is important for reducing repeated adjustment during processing.


 - Good Compatibility in Cleaning and Detergent Systems


Diethanolamine can be used in detergent and cleaning formulations where alkalinity, emulsification support and formulation balance are required. It is often considered in liquid detergents, industrial cleaners and related surfactant systems.


 - Useful in Corrosion Inhibitor and Metalworking Applications


DEA can be used as a component in corrosion inhibitor systems and metalworking-related formulations. It helps support pH adjustment, compatibility and performance balance in industrial fluid systems.


 - Application Support for Gas Treatment


Diethanolamine is also used in gas treatment processes to help remove acidic gases such as hydrogen sulfide and carbon dioxide from natural gas streams.



Main Applications of Diethanolamine


Corrosion Inhibitor

Diethanolamine can be used in corrosion inhibitor formulations to support pH adjustment, formulation balance and metal surface protection.


Liquid Detergents

In liquid detergents, DEA helps support alkalinity control, emulsification and compatibility with other surfactants.


Polishes

DEA can be used in polish formulations to improve emulsification, consistency and surface application performance.


Personal Care Products

In personal care products, Diethanolamine may support pH adjustment, emulsification and formulation stability, depending on the final formula.


Pharmaceuticals

DEA can be used as a chemical intermediate or functional material in pharmaceutical-related applications where suitable grade requirements are met.


Cleaners

In cleaner formulations, DEA helps improve alkalinity, emulsification and overall cleaning system stability.

Key Quality Indicators for Diethanolamine


DEA Content

Dotachem supplies Diethanolamine with DEA content of ≥99.3%. A stable DEA content helps customers maintain consistent performance when the product is used in detergents, cleaners, corrosion inhibitor formulations and other downstream applications.


Low Color

Color is an important indicator for formulations where appearance matters, such as polishes, personal care products and certain cleaning systems. Dotachem controls the color of Diethanolamine to ≤15 Pt-Co to support cleaner-looking finished products.


Controlled Water Content

Water content can affect formulation stability and downstream processing. Dotachem supplies DEA with water content ≤0.3%, helping customers reduce unnecessary variation during production.


Density Control

Density is often checked during quality inspection and batch comparison. Dotachem’s Diethanolamine has a density range of 1.090–1.095 at 20℃, supporting regular production and incoming material control.
