Monoethanolamine, also known as MEA, is an ethanolamine compound containing both a primary amine group and a hydroxyl group. It is a clear, colorless liquid with good miscibility in water and many organic solvents, and is widely used in surfactants, gas treatment, metalworking fluids, chemical intermediates and other industrial systems.
Dotachem supplies industrial-grade Monoethanolamine with MEA content ≥99.5%, low diethanolamine content, low color and controlled water content. With stable quality specifications and export supply experience, Dotachem can provide MEA for manufacturers that need reliable raw materials for continuous production and formulation use.

Dotachem supplies Monoethanolamine with MEA content ≥99.5%, helping customers maintain more consistent dosage, reaction performance and formulation results in continuous production.
Controlled diethanolamine content helps reduce unwanted secondary amine influence in downstream systems. This is important for customers using MEA in surfactant synthesis, gas treatment and chemical intermediate production.
With low color specification, MEA is suitable for applications where appearance, transparency or final product color matters, such as cleaning formulations, inks and selected chemical systems.
Lower and controlled water content helps reduce formulation fluctuation during storage, handling and production. This is especially useful for customers who need stable raw material input in repeated batches.
MEA is miscible with water and many organic solvents, making it easier to introduce into different industrial systems. This helps improve processing convenience in surfactants, metalworking fluids and pH adjustment formulations.
Because MEA contains both amine and hydroxyl groups, it can be used in neutralization, reaction and intermediate synthesis. This gives manufacturers more flexibility when using MEA in surfactants, additives and other downstream chemical products.

As a China-based ethanolamine manufacturer and supplier, Dotachem supports Monoethanolamine production and supply with its own production plant and a professional laboratory team of around 200 people. With mature production technology, stable product quality and sufficient supply capacity, Dotachem provides MEA sourcing support for customers in different markets worldwide.
Before quotation, Dotachem can check the required MEA content, DEA limit, color, water content and density with the customer. This helps avoid quoting a material that does not match the customer’s actual production standard.
For customers using MEA in surfactants, gas treatment, metalworking fluids, inks or chemical intermediates, Dotachem can help confirm whether the standard MEA specification is suitable for their formulation or process.
Dotachem provides free MEA samples in multiple specifications to help customers test product suitability before bulk orders. Customers can confirm the required grade, testing quantity and application details with our team before sample arrangement.
Dotachem can offer competitive and cost-effective MEA pricing for bulk orders, regular purchasing plans or full-container shipment. Price can be discussed based on order quantity, packaging type and delivery terms.
For available MEA stock, Dotachem can help shorten order preparation time. Packaging, loading and shipment schedules can be confirmed after order details are fixed.
After delivery, Dotachem can follow up on MEA use feedback, quality questions and future purchasing needs. If customers have questions during storage, handling or formulation use, our team can provide timely communication and support.
A: The shelf life of Monoethanolamine is usually confirmed according to packaging, storage conditions and product specification. MEA should be stored in a sealed container in a cool, dry and well-ventilated place, away from direct sunlight and incompatible materials.
A: Dotachem controls key indicators such as MEA content, diethanolamine content, color, water content and density during production and testing. Our factory and laboratory team support quality checks to help customers receive MEA that meets the agreed specification.
A: The MOQ depends on the required specification, packaging type, destination market and stock status. Customers can contact Dotachem with the target quantity and application details, and our team will confirm a suitable order plan.
A: Monoethanolamine can be supplied in industrial packaging such as drums, IBC or other bulk packaging options according to order requirements. Final packaging can be confirmed based on order quantity, storage needs and shipment arrangement.
