    AI Overview
    AEO (Alcohol Ethoxylate) sulphonation typically refers to the production of Alcohol Ether Sulfates (AES or SLES), a major anionic surfactant used in shampoos and detergents, rather than Alpha Olefin Sulfonate (AOS). The process involves reacting ethoxylated fatty alcohols with sulfur trioxide (
    SO3cap S cap O sub 3
    𝑆𝑂3
    ) in a falling film reactor, followed by neutralization. 
    Key Aspects of AEO/AES Sulphonation: 
    • Reaction: Alcohol ethoxylates are sulfated (often termed sulphonation in industrial contexts) using
      SO3cap S cap O sub 3
      𝑆𝑂3
       gas, creating an alkyl ether sulfate.
    • Properties: This process produces surfactants known for high foaming, good cleaning, and excellent solubility.
    • Application: Widely used in personal care, hair care, and household detergent products. 
    Common Alternatives in Surfactant Production: 
    • Alpha Olefin Sulfonate (AOS): Produced by sulfonating
      C14−16cap C sub 14 minus 16 end-sub
      𝐶14−16
       alpha olefins using a falling film reactor, creating a mix of alkene sulfonates and hydroxyalkane sulfonates.
    • Linear Alkylbenzene Sulfonate (LAS): Created via sulfonation of linear alkylbenzenes with
      SO3cap S cap O sub 3
      𝑆𝑂3
      .       
    AOS is often marketed as a sulfate-free alternative to SLES (the product of AEO sulfonation) and has a lower toxicity profile.
