What is Fatty Alcohol Polyoxyethylene Ether CAS 68213-23-0?

Fatty Alcohol Polyoxyethylene Ether CAS 68213-23-0 is a nonionic surfactant made by reacting C12-18 fatty alcohols with ethylene oxide. It is commonly called AEO or C12-18 ethoxylated alcohol and is used in detergents, cleaners, textile auxiliaries, degreasers, and emulsifier systems.

Why does CAS 68213-23-0 cover products with different EO numbers?

CAS 68213-23-0 is the broad registry entry for ethoxylated C12-18 alcohols rather than one exact ethoxylation level. Suppliers therefore use the same CAS for AEO-3, AEO-7, AEO-9, and related grades, with the actual product defined by the EO number and specification sheet.

How does the ethylene oxide number affect cloud point and HLB?

As the EO number increases, the molecule becomes more water-soluble, so HLB rises and the water-based cloud point generally increases. AEO-3 is oil-soluble with a low HLB, AEO-7 has an HLB around 12.0-13.0, and AEO-9 typically has an HLB around 13.0-14.0 with a water cloud point near 75-85 deg C.

What industrial applications is this AEO product used for?

AEO products are used in laundry detergents, household and hard-surface cleaners, industrial degreasers, textile dyeing auxiliaries, emulsification, and wetting. AEO-9 is often chosen as a more readily biodegradable alternative to nonylphenol ethoxylates such as NP-9.

Product Description

Fatty Alcohol Polyoxyethylene Ether, CAS 68213-23-0, also called AEO, is a nonionic surfactant made by reacting C12-18 fatty alcohols with ethylene oxide.

Synonyms: C12-18 Ethoxylated Alcohols; Polyethylene glycol cetyl/stearyl ether; AEO; Alcohols C12-18 ethoxylated.

CAS: 68213-23-0.

It has the general formula RO(CH2CH2O)nH, where R is a C12-18 alkyl chain and n is the average EO number.

AEO-3 is oil-soluble and used mainly as a W/O emulsifier or intermediate.

AEO-7 offers balanced wetting and emulsifying and is used in degreasers and textile auxiliaries.

AEO-9 is water-soluble with strong detergency, wetting and emulsifying power.

The EO number controls water solubility, HLB and cloud point; higher EO gives higher HLB and cloud point.

It is a key ingredient in laundry detergents and household cleaners.

It is used as a scouring, penetrating and leveling agent in textile dyeing.

It is used in industrial metal degreasing and hard-surface cleaners.

It is used in emulsifier systems for oils and fragrances.

AEO-9 is often chosen as a more readily biodegradable alternative to nonylphenol ethoxylates.

AEO-9 solidifies into a paste at low temperatures below 20°C, which is a normal physical property.

Confirm appearance, color, pH, cloud point, HLB, moisture and solubility for the required AEO grade.

Store in tightly closed containers in a cool, dry, well-ventilated place, away from moisture and direct sunlight.

Confirm packaging with the requested quantity and destination requirements.
