1. Chemical Synthesis

• Neutralizing Agent: Monoethanolamine is often used as a neutralizing agent for acidic components in various chemical processes. It helps in adjusting the pH of solutions in the production of various products, such as detergents and cosmetics.
• Gas Sweetening and CO₂ Capture: It is widely used in gas treatment plants to remove acidic gases such as hydrogen sulfide (H₂S) and carbon dioxide (CO₂) from natural gas and refinery gases. This process, known as gas sweetening, helps in purifying gas streams for safe processing and utilization.

2. Pharmaceuticals

• pH Adjuster: In pharmaceutical formulations, monoethanolamine is used to adjust pH levels, ensuring stability and enhancing the solubility of active ingredients. This is particularly useful in topical and injectable products where precise pH control is necessary.
• Active Ingredient in Dermatological Preparations: Monoethanolamine is sometimes used in combination with other agents in topical formulations to treat skin conditions due to its ability to penetrate the skin and alter its permeability.

3. Personal Care

• Surfactant and Emulsifier: Monoethanolamine is commonly used as a surfactant and emulsifier in shampoos, soaps, lotions, and creams. It helps stabilize emulsions and enhances the foaming properties of cleaning products, improving the user experience.
• pH Regulator: It serves as a pH regulator in cosmetic formulations, helping to maintain the desired pH level for optimal stability and performance of the product.

4. Fabric solution

• Scouring Agent: Monoethanolamine is used in the textile industry as a scouring agent to remove impurities, oils, and waxes from raw fibers, improving their dyeing affinity and overall quality.
• Leather Processing: In leather processing, monoethanolamine is employed to neutralize acidic residues and improve the softness and texture of the leather. It can also assist in the penetration of dyes and other chemicals during the tanning process.

5. Agrochemicals

• Herbicide and Pesticide Production: Monoethanolamine is utilized as a building block in the synthesis of various herbicides and pesticides. It enhances the solubility and stability of active ingredients, improving their effectiveness in agricultural applications.
• pH Buffering Agent: It is used in formulations for fertilizers and plant growth regulators to control pH levels, ensuring optimal conditions for nutrient availability and plant growth.

6. Cleaning & Disinfectants

• Detergents and Soaps: It is a key ingredient in the formulation of industrial and household cleaning products. Its ability to emulsify oils and fats makes it effective in removing grease and stains, which is why it is used in detergents, surface cleaners, and dishwashing liquids.
