Product Description
AEO-2 / Laureth-2 / C12-14 Fatty Alcohol Ethoxylate (2EO) CAS 3055-93-4 / 68439-50-9
Product Introduction
AEO-2, also known as Laureth-2 or C12-14 Fatty Alcohol Ethoxylate (2EO), is a nonionic surfactant belonging to the alcohol ethoxylates family. It is synthesized by the ethoxylation of C12-14 fatty alcohols with two moles of ethylene oxide. This product is characterized by its excellent emulsifying, wetting, and dispersing properties, with low foam and good compatibility with other surfactant types. It serves as a versatile intermediate and functional ingredient in numerous industrial and consumer formulations.

Product Functions
- Emulsifier: Efficiently emulsifies oils and fats in non-aqueous systems or for creating water-in-oil emulsions.
- Wetting Agent: Enhances wetting of surfaces in solvent-based systems.
- Intermediate: Key raw material for synthesizing sulfate, phosphate, or other derivatives (e.g., AES).
- Dispersant: Aids in the dispersion of pigments and solids in non-polar media.
- Low Foam: Ideal for applications where foam generation is undesirable.
- Compatibility: Exhibits excellent compatibility with anionic, cationic, and other nonionic surfactants.
Application Areas
- Detergent & Cleaning Industry: Intermediate for producing low-foam anionic surfactants like Sodium Laureth Sulfate (SLES) used in liquid detergents, shampoos, and car wash products.
- Textile Processing: Used as an emulsifier and wetting agent in solvent-based textile auxiliaries and dyeing processes.
- Agrochemicals: Acts as an emulsifier and penetrant in the formulation of pesticide and herbicide concentrates (EC formulations).
- Cosmetics & Personal Care: As a non-water-soluble intermediate for further derivatives used in creams, lotions, and hair care products.
- Paint & Coatings: Dispersant and wetting agent for pigments in solvent-based paint systems.
- Oil & Gas Industry: Component in drilling muds and oilfield chemical formulations.
- Polymer & Plastics: Can be used as an additive or processing aid.
Manufacturing Process
AEO-2 is produced via a controlled, catalytic ethoxylation reaction. The process involves reacting a blend of C12 and C14 linear fatty alcohols (derived from natural or synthetic sources) with ethylene oxide under precise temperature and pressure conditions. The reaction is catalyzed typically by an alkaline catalyst. The number of ethylene oxide moles added is strictly controlled to achieve an average of 2 EO units per alcohol molecule. Post-reaction, the product is neutralized, purified, and stabilized to meet specification standards.

Frequently Asked Questions
Q1: Is AEO-2 soluble in water?
A: No. AEO-2, with only 2 EO units, is not soluble in water. It is soluble in organic solvents and is primarily used in solvent-based systems or as a non-aqueous intermediate.
Q2: What is the main difference between AEO-2 and AEO-3 or higher EO numbers?
A: The key difference is water solubility. AEO-2 is water-insoluble, while AEO-3 and higher (typically ≥7 EO) become water-soluble. AEO-2 is favored for low-foam, solvent-based, or intermediate applications.
Q3: Can AEO-2 be used directly in aqueous shampoo formulations?
A: Not directly. It is commonly used as the key intermediate to produce its water-soluble anionic derivative, Sodium Laureth Sulfate (SLES), which is then used in shampoos and other aqueous products.
Q4: What are the storage conditions for AEO-2?
A: Store in a cool (below 40°C), dry, and well-ventilated area away from heat and open flames. Keep containers tightly sealed to prevent moisture absorption or contamination.
Q5: Do you provide technical data sheets (TDS) and safety data sheets (SDS)?
A: Yes. Comprehensive TDS and SDS (MSDS) are available for download upon request or can be provided with your order.
Q6: Can you customize the fatty alcohol chain length (C12 vs C14 ratio)?
A: Yes. We offer some flexibility in the carbon chain distribution of the base alcohol to suit specific application needs. Please contact our technical sales team for details.
