Is PEG-2 Oleamine the same material as higher-EO oleyl amine ethoxylates?

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.

What should a buyer specify in an RFQ for PEG-2 Oleamine?

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.

PEG-2 Oleamine CAS 13127-82-7

PEG-2 Oleamine, chemically described as (Z)-2,2′-(octadec-9-enylimino)bisethanol or bis(2-hydroxyethyl)oleylamine, is identified by CAS No. 13127-82-7, EC No. 236-062-2 and formula C22H45NO2. It is a tertiary fatty amine with two hydroxyethyl groups whose protonation changes with pH. Industrial grades are evaluated through amine values, water, color, physical form and application performance rather than an unsupported universal 99% claim.

Synonyms: Bis(2-hydroxyethyl)oleylamine, N,N-Bis(2-hydroxyethyl)oleylamine, 2,2'-[(9Z)-9-Octadecen-1-ylimino]diethanol, Dihydroxyethyl Oleylamine, Ethoxylated Oleylamine (2 EO), Oleyl Diethanolamine.
Einecs: 236-062-2
Molecular Formula: C₂₂H₄₅NO₂
Grade: Specify total and tertiary amine values, water, color, physical form, application pH and any supplier-defined composition limit; compare the current TDS and batch COA.
Package: State required quantity, physical form and destination; confirm the current bag or container, liner, net weight, temperature handling and transport requirements before quotation.

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

Keep tightly closed in a dry, ventilated area within the temperature limits stated by the supplier. Protect from incompatible acids, oxidizers or other materials identified by the exact SDS, and follow approved conditioning instructions if physical form changes.

Safety, documentation and procurement

Fatty amines can require stringent eye and skin protection. Follow the current SDS for PPE, ventilation, spill response, transport and disposal. A quotation should state amine-value limits, application pH, performance target, package, quantity, destination and required documents.

For other ethoxylated amine pages, compare Polyoxyethylene Coco Amine CE-10, Ethoxylated Lauryl Amine, and Tallow Amine Ethoxylate TA-15.
