Monoethanolamine (MEA) – Versatile Chemical for Industry

Monoethanolamine (MEA) 99% is a clear to pale liquid amine widely used in gas treatment, detergents, metalworking fluids, textiles, chemical production, cement additives, and many other industrial processes. It combines the properties of both an alcohol and an amine, which makes it useful for neutralization, pH control, emulsification, and chemical synthesis.

MEA has the chemical formula C₂H₇NO and a molecular weight of approximately 61.08 g/mol. Because it is strongly alkaline and highly soluble in water, manufacturers use it in applications that require fast neutralization and reliable chemical performance. Basekim supplies Monoethanolamine 99% for international bulk orders according to required specifications, packaging, and destination.

Monoethanolamine 99% Specifications

Industrial buyers should check the actual technical data before placing an order because purity, water content, color, and density can affect final performance.

Exact values may vary slightly by production source. Therefore, the current TDS should always be used for final approval.

What Is Monoethanolamine?

Monoethanolamine is the simplest member of the ethanolamine family.

It contains both an amine group and a hydroxyl group, so it can participate in many different chemical reactions. This dual functionality explains why MEA appears in such a wide range of industrial formulations.

In practice, manufacturers use it when they need:

• Strong alkalinity

• Acid neutralization

• pH adjustment

• Gas absorption

• Surfactant production

• Corrosion-control formulations

• Chemical intermediates

It is highly miscible with water and also blends well with many organic materials.

For buyers comparing industrial specifications, additional technical product information can help when evaluating suitable material for specific processes.

Why MEA 99% Is Widely Used

The 99% grade provides a high concentration of active material.

As a result, manufacturers can control dosage more accurately and avoid introducing unnecessary water into the production process.

This is especially useful in:

• Gas treatment units

• Detergent manufacturing

• Chemical synthesis

• Metalworking fluids

• Cement and concrete additives

• Textile processing

In addition, high-purity MEA usually offers more consistent performance than lower-concentration products.

Monoethanolamine Uses

The main uses of MEA come from its strong alkalinity, water solubility, and chemical reactivity.

Gas Treatment

Gas treatment is one of the best-known applications.

MEA can absorb acidic gases such as:

• Carbon dioxide

• Hydrogen sulfide

For this reason, it has long been used in gas sweetening and purification systems.

However, the best amine depends on process conditions such as:

• Gas composition

• Operating pressure

• Temperature

• Required removal efficiency

• Energy consumption

• Corrosion control

MEA is often selected when fast reaction with acidic gases is important.

Detergents and Cleaning Products

Detergent manufacturers use monoethanolamine to control pH and neutralize acidic ingredients.

It can also support the production of surfactants and cleaning agents.

Common applications include:

• Industrial cleaners

• Degreasers

• Laundry formulations

• Household cleaners

• Specialty detergents

In these systems, MEA can improve alkalinity and support cleaning performance.

However, formulators must control dosage carefully because excessive alkalinity may affect product stability or material compatibility.

Metalworking Fluids

MEA is also used in selected metalworking formulations.

It can help maintain an alkaline environment and support corrosion protection when combined with suitable additives.

Applications may include:

• Cutting fluids

• Grinding fluids

• Machining fluids

• Water-based metalworking products

Its role depends on the complete formulation, so manufacturers usually test MEA alongside lubricants, corrosion inhibitors, biocides, and surfactants.

Textile Processing

Textile manufacturers may use MEA in pH adjustment, dyeing processes, and chemical treatment systems.

Because it is water soluble, it can be easy to introduce into aqueous formulations.

Depending on the process, it may support:

• Fiber treatment

• Dyeing

• Finishing

• Chemical neutralization

The required dosage depends on the textile material and final process conditions.

Cement and Construction Chemicals

Ethanolamines also appear in selected cement and concrete additive systems.

MEA may be used as a component in formulations designed to support:

• Cement grinding

• Performance control

• Processing efficiency

• Admixture chemistry

However, formulation design matters. Manufacturers should not use a fixed dosage without testing because different cement types can respond differently.

Chemical Manufacturing

Monoethanolamine serves as an intermediate in many chemical reactions.

Manufacturers use it to produce:

• Surfactants

• Emulsifiers

• Corrosion inhibitors

• Specialty chemicals

• Detergent intermediates

• Agricultural chemicals

Its reactive amine and alcohol groups make it a useful building block in chemical synthesis.

Monoethanolamine vs Diethanolamine vs Triethanolamine

MEA belongs to the same chemical family as DEA and TEA, but their properties and applications differ.

MEA generally provides stronger alkalinity and lower molecular weight.

TEA, on the other hand, is more viscous and often preferred in formulations where milder alkalinity and different emulsification behavior are useful.

Therefore, manufacturers should select the ethanolamine according to process requirements rather than simply choosing by price.

Solubility and pH Behavior

MEA mixes easily with water.

Its aqueous solutions are strongly alkaline, but the actual pH depends on concentration.

For this reason, a single fixed pH value should not be used for every MEA solution.

In process design, buyers should consider:

• Product concentration

• Final dilution

• Temperature

• Other formulation ingredients

• Target pH

These factors determine the actual performance of MEA in the finished system.

Packaging

Monoethanolamine is commonly supplied in industrial packaging designed for chemical transport and storage.

Available options may include:

• Steel drums

• IBC tanks

• ISO tanks

• Bulk shipment

The correct option depends on order size, destination, and transportation method.

Before placing an order, buyers should confirm:

• Net weight

• Packaging material

• Container loading

• Label requirements

• Country of origin

• Export documents

• SDS

• TDS

Monoethanolamine Price

Monoethanolamine price changes according to market conditions.

Important factors include:

• Purity

• Order quantity

• Packaging

• Production origin

• Feedstock costs

• Freight rates

• Destination

• Incoterm

• Market availability

Because chemical prices change over time, old fixed prices can quickly become inaccurate.

Therefore, buyers should request a current quotation based on required quantity, packaging, and destination.

Storage and Handling

MEA requires careful handling because it is strongly alkaline and corrosive.

Store the product in tightly closed containers and protect it from contamination.

Workers should use suitable personal protective equipment according to the SDS.

This may include:

• Chemical-resistant gloves

• Eye protection

• Face protection

• Protective clothing

Facilities should also provide good ventilation and emergency washing equipment.

Contact with skin and eyes should be avoided.

Safety Information

Monoethanolamine should not be described as harmless or only mildly hazardous.

Depending on classification and concentration, it can cause:

• Severe skin damage

• Serious eye damage

• Irritation

• Harmful effects through certain exposure routes

Therefore, workers should follow the latest SDS and workplace safety rules.

In addition, MEA should be stored away from incompatible materials such as strong acids and certain reactive chemicals.

Related Industrial Raw Materials

Companies that source ethanolamines often also purchase other process materials for manufacturing, coatings, packaging, and formulation work.

For applications that require solid petroleum-based materials rather than liquid amines, buyers can also review high-purity refined wax grades used in coatings, candles, rubber, packaging, and related industrial processes.

These materials serve completely different functions, so buyers should select them according to their own technical requirements.

SDS and TDS

The SDS and TDS are essential documents for professional buyers.

The TDS normally includes:

• Purity

• Appearance

• Water content

• Density

• Chemical properties

• Typical specification

The SDS provides:

• Hazard information

• First aid

• Storage guidance

• Personal protection

• Spill response

• Fire handling

• Transport information

Buyers should always review the latest version before use.
