• Basic Information:
  • Molecular Formula: Generally expressed as RO(CH2​CH2​O)n​H, where R is usually a C12​ or C12​−C14​ hydrocarbon group.
  • CAS No.: 68439 - 50 - 9
  • Synonyms: Fatty Alcohol Polyoxyethylene Ether, Polyethoxylated Alcohol, Lauryl Alcohol Polyoxyethylene Ether, etc.
• Physical and Chemical Properties:
  • Appearance: Usually colorless liquid to white solid. As the addition number of ethylene oxide increases, the state changes from liquid to solid.
  • Melting Point: 41 - 45 °C.
  • Boiling Point: 100 °C.
  • Flash Point: >230 °F.
  • Solubility: Products with a low addition number of ethylene oxide are easily soluble in oil and organic solvents, while those with a high addition number are soluble in water. For example, AEO - 3 and AEO - 5 are easily soluble in oil, and AEO - 7 and AEO - 9 are easily soluble in water.
  • HLB Value: It varies according to the addition number of ethylene oxide. For example, the HLB value of AEO - 3 is about 7, and that of AEO - 15 is 14.5.
  • Stability: The ether bond in the molecule is not easily destroyed by acids and alkalis, with high stability. It is hydrolytically stable in the pH range of 3 - 11, but will be slowly oxidized in the air.
• Product Characteristics: It has good detergency, wetting property, emulsifying property, and hard - water resistance, as well as excellent biodegradability and low foam. It has good compatibility with other surfactants, is not sensitive to hard water, and has good washing performance at low temperatures. However, its solubility will gradually decrease with the increase of water temperature.
• Preparation Method: Using sodium hydroxide as a catalyst, long - chain fatty alcohols undergo a ring - opening polymerization reaction with ethylene oxide in the absence of water and oxygen.
• Application Fields:
  • Detergent Industry: It is the main active ingredient in hand sanitizers, laundry detergents, body washes, etc., playing the roles of emulsification, foaming and decontamination.
  • Textile and Dyeing Industry: As a textile and dyeing auxiliary, it can be used as an emulsifying silicone oil, penetrant, leveling agent, etc.
  • Paper - making Industry: It can be used as a deinking agent, blanket cleaner, and deresinifying agent.
  • Other Fields: It is also used as a pesticide emulsifier, crude oil demulsifier, lubricating oil emulsifier, etc.
• Packaging and Storage: Liquid products are usually packed in 180 - Kg iron drums or plastic drums. Solid products can be packed in kraft paper woven bags with an inner plastic bag, 25 Kg per bag. It should be stored in a cool, dry and ventilated place, and the shelf - life is generally 1 year.
