C9-11 Alcohol Ethoxylate CAS 68439-46-3

What C9-11 Alcohol Ethoxylate Is

C9-11 alcohol ethoxylate belongs to the fatty alcohol ethoxylate family, with the general structure R-O-(CH2CH2O)n-H where R is a C9 to C11 primary, mostly linear to lightly branched alkyl group and n is the average number of ethylene oxide units. The C9-11 feed and ethoxylation route give a fast wetting, low to moderate foaming nonionic surfactant that biodegrades readily. Grades are named by the EO count, as C9-11 pareth or under 91-series brand equivalents, and the EO count moves the product from a clear, oil soluble liquid at the low end to a hazy liquid and then a white soft paste or waxy solid as EO rises. UATChem supplies the range by EO grade, with HLB, cloud point, pH and appearance reported on the COA or TDS for each grade rather than as a single assay figure.

Cleaning, Emulsifying and Process Use

• Household and I&I cleaners. Detergency and wetting in laundry, dishwash and hard surface liquids, usually blended with anionic surfactants.
• Hard surface, metal and oilfield. Degreasing, metal cleaning, CIP, transport and oilfield jobs that need fast wetting and soil removal.
• Agrochemical and polymer emulsions. Emulsifying and dispersing in crop protection emulsifiable concentrates or EW formulations and in emulsion polymerization.
• Textile and personal care. Scouring, wetting and level dyeing in textiles, with higher EO pareth grades used in mild hair and skin care formulas.

Typical Specifications

Because this is an ethoxylate range rather than one fixed molecule, EO moles, HLB, cloud point and form vary by grade and are confirmed on the TDS and COA; active matter and residual ethylene oxide follow the agreed specification, and the entries below describe the family.

Packaging, Documents and Ordering

• Supplied in 200 kg drums, 1000 L IBC totes and bulk tankers. Drums and totes stay sealed in a cool, ventilated place, liquids are protected from freezing, and paste or waxy high EO grades can be gently warmed before discharge; the material is kept away from strong oxidizers.
• C9-11 alcohol ethoxylate is handled as an industrial surfactant with standard eye and skin protection, and the exact hazard and transport data follow the SDS. Every lot carries a TDS and COA with EO mole ratio, HLB, cloud point, pH, appearance and water content, and formulation samples can be discussed at inquiry.
• For a quote, UATChem needs the EO grade or target HLB, quantity, packing (drum, IBC or tanker) and destination port.

FAQ

Q: What is C9-11 alcohol ethoxylate used for?

A: It is a biodegradable nonionic surfactant for cleaning and wetting, and an emulsifier for agro, polymer and textile work.

Q: How do EO moles change C9-11 alcohol ethoxylate?

A: Low EO grades are clear liquids for wetting; higher EO grades are water soluble pastes with high HLB for detergents.

Q: What packaging is used for C9-11 alcohol ethoxylate?

A: It ships in 200 kg drums, 1000 L IBCs or tankers, sealed against freezing and oxidizers; paste grades warmed before discharge.
