Isodecyl Alcohol Ethoxylates

Isodecyl alcohol ethoxylates are nonionic surfactants made by ethoxylating isodecyl alcohol (branched C10) with ethylene oxide. Changing the EO level moves the product from oil-soluble co-emulsifier toward water-dispersible wetting and detergency grades, so selection starts with the required HLB and the phase the product must live in.

Isodecyl alcohol ethoxylates are branched-C10 nonionics; EO level is set to the wetting/detergency target — confirm the available grade window with Esteem. Full family context is on the Alkoxylates hub. For grade selection beyond this page, Esteem’s R&D and QA teams work from the application brief rather than a catalogue guess.

Applications

• Hard-surface and industrial cleaning needing fast wetting from a branched hydrophobe.
• Textile and agro wetting where low foam variants may be preferred (confirm foam on trial).
• Emulsification of lighter oils where a C10 branched chain packs well.

How to select the grade

• Branched hydrophobes wet fast and can lower dynamic surface tension versus linear analogues.
• Balance EO for cloud point in hot or electrolyte-heavy systems.
• State use temperature, electrolyte load and foam ceiling — branched grades still need a cloud-point check.

How to specify on an RFQ

Send the application, the property that must not fail (HLB/emulsion stability, wetting, foam, feel or solubility), target specification, and trial quantity. That lets Esteem match the grade to your test method instead of quoting the nearest catalogue name. Current TDS, SDS and lot COA are shared for qualified enquiries through the document library route.
