MOA-12 (AEO-12) is a nonionic surfactant characterized by excellent emulsifying, wetting, and detergency capabilities, along with outstanding acid-alkali stability and hard water tolerance, making it suitable for a wide range of applications.
Detailed Description
MOA-12 (Lauryl Alcohol Polyoxyethylene Ether-12, CAS No.: 68439-50-9) is a high-polymerization-degree fatty alcohol polyoxyethylene ether nonionic surfactant produced by Guoli Chemical. It appears as a white to slightly yellow paste or waxy solid, possessing good physical form stability for easy storage and accurate dosing under different process conditions.
The core performance of this product is manifested in three main aspects: Excellent emulsifying ability, effectively reducing oil-water interfacial tension and forming stable emulsions; Outstanding wetting performance, quickly spreading on solid surfaces, significantly enhancing the diffusion efficiency of liquids at interfaces; Reliable detergency, showing good removal effects on various types of soil. These three core properties make it an irreplaceable surfactant component in many industrial formulations.
Particularly noteworthy is its excellent chemical stability—it remains structurally stable in both acidic and alkaline media, while exhibiting excellent tolerance to calcium and magnesium ions in hard water, making it less prone to precipitation. This characteristic ensures that the product's performance is not affected under complex water conditions and different pH process environments, making it especially suitable for industrial applications in areas with poor water quality.

Application Suggestions
MOA-12 is widely applicable in the following fields, with different compounding schemes available depending on the specific application scenario:
- Textile Dyeing and Finishing Auxiliaries: Used as a core component in scouring agents and detergents for pretreatment scouring and post-dyeing soaping of cotton, polyester, and other fabrics, effectively removing natural impurities and unfixed dyes from fibers.
- Industrial and Household Liquid Detergents: Enhances detergency and foam stability in formulations such as laundry liquids, dishwashing detergents, and hard surface cleaners, with good emulsifying and removal effects on various oil stains.
- Leather Degreasing Agents: Rapidly penetrates between leather fibers in the degreasing process, efficiently emulsifying and removing natural fats, creating favorable conditions for subsequent tanning and dyeing.
- Pesticide Emulsifiers: Helps disperse pesticide active ingredients stably in the aqueous phase, forming a homogeneous emulsion, improving the spreading and adhesion of the spray liquid on plant leaves.
- Cosmetic Emulsifying and Solubilizing Agents: Used in creams, lotions, makeup removers, etc., to promote the dispersion of oil-soluble ingredients in the aqueous phase, reducing greasiness and providing a mild, smooth user experience.
- Metal Hard Surface Cleaners: Compounded in industrial cleaners for metal parts, equipment housings, etc., effectively removing mineral oils, cutting fluids, rust preventives, and other oily soils, with good compatibility with metal substrates.
Precautions
- Eye Protection: This product may cause mild eye irritation (GHS Category 2B). It is recommended to wear chemical safety goggles during operation. In case of eye contact, flush with plenty of water for at least 15 minutes.
- Skin Contact: Non-irritating under normal use (Rabbit skin irritation index 0.0), but prolonged or repeated contact may cause skin dryness. It is recommended to wear nitrile or neoprene gloves.
- Storage Conditions: Recommended storage temperature is 5–40°C, avoiding freezing or overheating. If the product freezes, slowly thaw and stir evenly before use.
- Environmental Disposal: This product is readily biodegradable (OECD 301 method, >60% degradation in 28 days), but discharge should still be strictly controlled to avoid direct release into sewers or water bodies. Toxic to aquatic organisms (Fish 96h LC50: 1–10 mg/L).
- Avoid Coexistence: Store away from strong oxidizers, strong acids, strong bases, as well as heat sources, sparks, and open flames.
