PEG-2 Oleamine (CAS 13127-82-7), also called bis(2-hydroxyethyl)oleylamine or dihydroxyethyl oleylamine, is a tertiary fatty amine with two hydroxyethyl groups. Its degree of protonation depends on pH, affecting its behavior in industrial formulations where it serves as an antistatic, emulsifying, dispersing, wetting or corrosion-inhibiting component. Total and tertiary amine values, water content, color and physical form are key specification parameters. COA, TDS and SDS are available to support specification review and safe handling.

Quality controls and analytical reports
Total and tertiary amine values are assessed by titration, while water content can be measured by Karl Fischer testing. Compare amine values using the same test method and reporting basis. Composition or impurity reports, including GC/GC-MS chromatograms where applicable, can be provided for the agreed grade and analytical purpose. Chromatographic peak-area percentages do not establish total mass purity.
Applications and grade selection
PEG-2 Oleamine is evaluated as an antistatic, emulsifying, dispersing, wetting or corrosion-inhibiting component in polymers, textiles, cleaning, metal-treatment and other industrial formulations. Suitability changes with pH, counter-ion, substrate and the remaining surfactant system.
- For acid-cleaning use, test viscosity response, stability, metal compatibility and corrosion performance at the actual acid concentration.
- For plastics or textile antistatic use, evaluate migration, surface resistance, processing behavior and downstream compatibility.
- Do not assume compatibility with strong anionics; test concentrates and use dilutions across the intended pH range.
Storage and handling
Store tightly closed in a dry, ventilated area under the temperature and handling conditions in the grade-specific TDS and SDS. Follow the stated conditioning or homogenization instructions before sampling and use.
Safety, documentation and procurement
Follow the grade-specific SDS for eye and skin protection, ventilation, spill response, transport and disposal. Send the reference specification or intended application, quantity and destination for a quotation; include the working pH and critical performance requirements if known.
For other amine ethoxylate grades, compare Polyoxyethylene Coco Amine CE-10, Ethoxylated Lauryl Amine and Tallow Amine Ethoxylate TA-15. These differ in fatty-amine feedstock and ethoxylation grade; compare amine values and formulation performance before substitution.
In industrial cleaning formulations, Fatty Alcohol Ethoxylate AEO-7 is a nonionic co-surfactant candidate for solubilization and flow adjustment. Test the complete blend at its intended pH and electrolyte level; AEO-7 is a different ingredient, rather than a replacement for PEG-2 Oleamine.
FAQ - Technical & Supply Chain
-
Q:
Is PEG-2 Oleamine the same material as higher-EO oleyl amine ethoxylates?
A: No. CAS 13127-82-7 corresponds to the two-EO oleyl-amine derivative, while higher-EO oleyl amines are different grades or substances. Their amine equivalent, hydrophilic balance, salt response, and formulation behavior can differ; compare the exact identity and grade specification before substitution. -
Q:
What should a buyer specify in an RFQ for PEG-2 Oleamine?
A: State the required total and tertiary amine values, water, color, physical form, application and working pH, quantity and destination. If a reference grade is being replaced, include its specification or COA and the performance test used for comparison.
