What is Ethoxylated Oleyl Amine (12EO) CAS 26635-93-8?

It is a tertiary amine ethoxylate prepared from primary oleylamine and an average of about 12 moles of ethylene oxide. This CAS number identifies the oleylamine ethoxylate family and is commonly associated with Ethomeen O/12.

Why is it often compared with Ethomeen O/12?

Ethomeen O/12 is a widely used trade-name oleylamine ethoxylate with the same chemical family and 12EO description. The generic product is functionally equivalent for many emulsifying, dispersing, and corrosion-inhibition applications, but users should still confirm the supplier specification.

Is it nonionic or cationic?

Its behavior depends on pH and formulation conditions. The ethoxylated amine can behave as a nonionic surfactant in neutral or alkaline systems and become more cationic when protonated in acidic systems.

What HLB should formulators expect?

The Ethomeen O/12 reference has an HLB of about 9.9 on the Davies scale. This moderate value supports oil-in-water emulsification, wetting, and dispersing while keeping compatibility with a range of industrial formulation components.

What are the main industrial uses?

It is used as an emulsifier, dispersant, wetting agent, or adjuvant in agrochemical formulations, textile processing, coatings, and industrial cleaners. It can also provide corrosion inhibition, thickening, and antistatic effects in specialty systems.

Product Description

Ethoxylated Oleyl Amine (12EO) CAS 26635-93-8 is a tertiary amine ethoxylate prepared from oleylamine and an average of about 12 moles of ethylene oxide.

Synonyms: Oleylamine Ethoxylate (12EO); Ethoxylated Oleylamine; Oleyl Amine EO 12; equivalent to Ethomeen O/12.

CAS: 26635-93-8.

It is supplied as an amber to brown liquid or semi-liquid.

It is positioned as a surfactant intermediate for industrial formulation systems.

It provides wetting, emulsifying, and dispersing functionality.

It is used as an emulsifier, dispersant, or adjuvant in agrochemical formulations.

It is used as a wetting agent and softening auxiliary in textile processing.

It is used in coatings and inks as a dispersing and compatibility agent.

It is used in industrial cleaning and specialty chemical formulations.

Its behavior depends on pH: it can be nonionic in neutral or alkaline systems and more cationic when protonated in acidic systems.

Confirm the required grade, HLB, amine value, appearance, and related specifications for the chosen grade.

Check compatibility with the target formulation and confirm the supplier specification for functional equivalence.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from direct sunlight and moisture.

Because viscosity rises at low temperature, mild warming may be needed before pumping or handling.

Confirm packaging suitable for the liquid or semi-liquid form and order quantity, and follow the current SDS.

Confirm grade, packaging, and specification as required.
