Description

Monoethanolamine Oleate is an organic salt formed from monoethanolamine and oleic acid, widely recognized by its CAS registry number 2272-11-9. This versatile compound serves as a highly effective emulsifier, corrosion inhibitor, and surfactant, providing critical functionality in demanding industrial formulations. It is an essential raw material for manufacturers in the lubricant, metalworking, textile, and personal care industries seeking stable, high-performance additives.

Application

• Metalworking Fluids & Corrosion Inhibitors: Acts as a powerful emulsifier and corrosion inhibitor in soluble oils and synthetic coolants, protecting ferrous and non-ferrous metals.
• Textile Processing: Used as a softening agent, lubricant, and antistatic agent in fiber production and fabric finishing.
• Lubricant & Grease Additives: Functions as a thickening agent, emulsifier, and anti-wear component in specialty lubricants and greases.
• Personal Care & Cosmetics: Serves as an emulsifier and opacifying agent in creams, lotions, and hair care products.
• Agricultural Adjuvants: Employed as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adhesion.
• Industrial Cleaners: Used in heavy-duty degreasers and cleaning formulations for its surfactant and saponification properties.
• Paint & Coatings Additive: Acts as a dispersing agent and corrosion inhibitor in water-based coatings and primers.

Quality Control

Our Monoethanolamine Oleate is produced under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, acid value, amine value, moisture content, and identification is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture and caking. Keep away from strong oxidizing agents and acids.
