C9-C11 alcohol ethoxylate

What is C9-C11 alcohol ethoxylate?

C9–C11 alcohol ethoxylate (CAS 68439-46-3) is a nonionic surfactant from linear primary C9, C10, and C11 alcohols (75–85% of blend; MW 158–164). Linear structure supports efficient surface activity and biodegradability versus branched alternatives.

What is C9-C11 alcohol ethoxylate used for?

Ethoxylation tunes HLB for wetting, emulsification, dispersion, and detergency. Shorter chain length versus C12+ alcohols delivers strong wetting—valued in industrial and institutional cleaning and emulsifiable concentrate production.

HLB and performance

Ethoxylation tunes HLB for wetting, emulsification, dispersion, and detergency. Shorter chain length versus C12+ alcohols delivers strong wetting—valued in industrial and institutional cleaning and emulsifiable concentrate production.

Available grades

Venus manufactures C9–C11 ethoxylates at average 2.5, 4, 6, and 8 moles EO. Lower EO grades favour oil solubility and EC formulations; higher EO grades improve aqueous detergency and water solubility.
