MOA-3 (AEO-3) is a fatty alcohol polyoxyethylene ether with a degree of polymerization of 3, belonging to the low-EO number nonionic surfactants. Compared with similar products of higher EO numbers (such as AEO-7, AEO-9), MOA-3 has a lower HLB value (approximately 8-9) and stronger lipophilicity, which gives it an irreplaceable emulsifying advantage in water-in-oil (W/O) emulsion systems. In contrast, AEO-7/AEO-9 and other products have higher HLB values (12-14), making them more suitable for O/W emulsification systems, with a fundamental difference in application positioning.
Among similar low-EO number products (such as AEO-2), the advantage of MOA-3 lies in its more balanced EO distribution, combining oil solubility with a certain degree of water dispersibility. AEO-2 is too lipophilic and has poor water dispersibility; while MOA-3 maintains excellent W/O emulsifying power while offering better formulation compatibility and operational convenience. In addition, MOA-3 is a standard-grade intermediate raw material for synthesizing AES (sodium alcohol ether sulfate). Its EO chain length directly determines the foaming, mildness, and viscosity characteristics of the final AES product, making it the industry-recognized optimal choice.
In terms of product quality itself, Guoli Chemical's MOA-3 features high purity active content (effective ingredients ≥99%), light color (colorless to slightly yellow transparent), and low residual by-products such as polyethylene glycol, which makes downstream products more stable, formulation design more precise, and dosage more economical, offering overall cost-effectiveness superior to low-purity similar products on the market.

1. AES Production: MOA-3 is the industry standard raw material for producing AES. After sulfonation, the resulting AES exhibits ideal foaming power, mildness, and thickening properties, making it the core surfactant in shampoos, body washes, and facial cleansers. Choosing high-purity MOA-3 can significantly improve the first-grade product ratio of AES.
2. W/O Emulsion Preparation: In formulations requiring water-in-oil emulsification systems (such as certain skin creams, metalworking water-in-oil emulsions), MOA-3 is the preferred emulsifier due to its low HLB value, offering emulsion stability superior to hydrophilic emulsifiers like AEO-7/AEO-9.
3. Textile and Leather Processing: When used as a scouring agent and degreasing agent, MOA-3's strong penetration and excellent oil removal efficiency surpass those of high-EO number products, making it especially suitable for cotton pretreatment and raw hide degreasing processes.
4. Metal Cleaning: Its strong degreasing power and rapid wetting ability make it perform excellently in heavy oil dirt cleaning scenarios. It can be compounded with high-EO number products to achieve optimal cleaning balance.
