Cetostearyl Alcohol Ethoxylate

Cetostearyl Alcohol Ethoxylate is a nonionic surfactant made by ethoxylating cetostearyl alcohol (C16–C18) 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.

Esteem lists ceto stearyl alcohol ethoxylates in the 2.5–80 EO mole range; both singular and plural searches (cetostearyl alcohol ethoxylates) refer to this family. 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

• Cream and lotion emulsification where cetostearyl body is familiar.
• Hair care emulsions and conditioning creams.
• Pharma-style ointment and cream bases (technical grades; confirm regulatory need).

How to select the grade

• Low EO (about 2–3) behaves as a lipophilic co-emulsifier; mid-to-high EO becomes the hydrophilic O/W partner.
• Match required HLB of the oil phase rather than copying a dose from a different oil.
• State EO moles, melt/appearance and whether the grade must pair with cetostearyl alcohol itself.

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.
