    2-Ethylhexanol Ethoxylate CAS 26468-86-0

    2-Ethylhexanol Ethoxylate (CAS 26468-86-0), also called PEG-2-Ethylhexyl Ether or POE 2-Ethylhexyl Ether, is a family of branched nonionic alcohol ethoxylates. Commercial grades differ in nominal EO level; hydroxyl value, active matter content, water content and physical form are also key parameters for grade selection. A Certificate of Analysis (COA), Technical Data Sheet (TDS) and Safety Data Sheet (SDS) can be provided for the supplied grade.

    Identity and physicochemical profile

    ItemTechnical guidance
    Product identity2-Ethylhexanol Ethoxylate; branched C8 alcohol ethoxylate family
    CAS number26468-86-0
    Nominal formulaC₈H₁₇O-(CH₂CH₂O)ₙ-H; n and the homolog distribution vary with the commercial grade
    Typical physical formLiquid, waxy or solid, depending on the EO profile, homolog distribution and temperature; see the grade TDS.
    Key quality controlsNominal EO and homolog distribution, hydroxyl value (mg KOH/g), water content, agreed active matter, appearance and color; pH and cloud-point results must state their test conditions.

    Hydroxyl value is reported in mg KOH/g using the stated titration method. Water results should identify the Karl Fischer procedure and reporting basis. Report pH with the aqueous dilution and temperature, and cloud point with the product concentration, medium and procedure.

    For chromatographic quality data, the method must cover the intended homolog range or target residuals, with calibration and result units stated. Homolog-distribution measurements and targeted residual tests serve different purposes. Relevant analytical reports can be provided for grade evaluation.

    Applications and grade selection

    2-Ethylhexanol Ethoxylates are evaluated as wetting agents and emulsifiers in industrial cleaning and textile processing. Selected grades are used in water-based alkaline cleaners, metal-cleaning formulations and drilling fluids. EO level and homolog distribution affect solubility, wetting and foam behavior, so performance is assessed in the intended formulation.

    • For grade comparison, use a nominal EO specification or a reference grade; application details can also guide selection.
    • Measure wetting and foam under the actual concentration, water hardness, pH, electrolyte, temperature and process conditions.
    • Do not transfer one grade’s HLB, cloud point, solubility or physical form to every product under the shared CAS number.

    Storage and handling

    Keep containers closed in a dry, ventilated area and follow the storage temperatures in the supplied grade TDS and SDS. Where temperature changes affect viscosity or physical form, follow the grade instructions for conditioning and mixing before sampling.

    Safety, documentation and procurement

    Use the current grade SDS for protective equipment, incompatibilities, transport, spill response and disposal. For a quotation, send the grade or intended application, approximate quantity and destination. Test requirements, samples and packaging can be agreed for the order.

    For cleaning and wetting formulations, compare Isotridecyl Alcohol Ethoxylate, C9-11 Alcohol Ethoxylate, and AEO-7 for differences in alcohol-chain structure, EO profile, foam and cloud behavior. Substitution requires evaluation in the complete formulation.

    FAQ - Technical & Supply Chain

    • Q:

      Does CAS 26468-86-0 identify one fixed 2-ethylhexanol ethoxylate grade?

      A: No. It identifies an ethoxylate family; commercial grades can differ in average EO level and therefore in solubility, cloud point, wetting, foam, and physical form. Compare the offered EO profile, hydroxyl value, water, test methods, and the formulation result rather than CAS alone.
    • Q:

      Is 2-Ethylhexanol Ethoxylate the same as 2-ethylhexanol (2-EH)?

      A: No. 2-Ethylhexanol (2-EH, CAS 104-76-7) is the unethoxylated alcohol used as a starting material. 2-Ethylhexanol Ethoxylate (CAS 26468-86-0) is an ethoxylated family with different nominal EO levels and homolog distributions. EO/PO alkoxylates also contain oxypropylene units and require their own grade identity. These products are not automatically interchangeable.
