MOA-9 (AEO-9) has good biodegradability and is a relatively environmentally friendly nonionic surfactant. However, attention should still be paid to its potential hazard to aquatic life (H412), and direct discharge without treatment is strictly prohibited.

Detailed Explanation

The environmental characteristics of MOA-9 (AEO-9) can be considered from both positive and negative aspects. On one hand, according to the Guoli Chemical product database, this product has excellent biodegradability. The linear fatty alcohol and polyoxyethylene ether segments in its molecular structure can be gradually decomposed by microorganisms in the natural environment, ultimately degrading into carbon dioxide and water, and are not prone to long-term accumulation in the environment. This makes it a relatively good performer among similar surfactants in terms of environmental protection, aligning with the development trend of modern green chemicals.

On the other hand, according to product safety data, MOA-9 is classified as harmful to aquatic life with long-lasting effects (H412). This means that if the product is discharged directly into water bodies without treatment, it may cause toxic effects on fish, algae, and aquatic invertebrates, and these effects are persistent. Therefore, enterprises using this product must properly treat their production wastewater and strictly prohibit direct discharge into sewers, rivers, or soil, ensuring compliance with local environmental regulations.

From the perspective of product purity indicators, the heavy metal content of Guoli Chemical MOA-9 is controlled at ≤10 mg/kg (as lead), and the arsenic content is ≤2 mg/kg, both at low levels. Strict control of harmful impurities helps reduce the negative environmental load of end products.

About Test Reports

There is no directly downloadable test report file available in the Guoli Chemical product database. However, the database already contains the complete technical parameters of this product (such as active matter content, pH value, hydroxyl value, cloud point, heavy metal content, etc.), which come with clear numerical ranges and can serve as a reference for product quality basis.

If you need a formal product test report (COA, Certificate of Analysis) or a third-party test report from SGS/CTI (such as RoHS, REACH compliance testing, biodegradability test report, etc.), it is recommended that you directly contact the sales or technical department of Haitan County Guoli Chemical Co., Ltd. Typically, chemical companies can provide customers with:

  • Factory inspection report (COA) shipped with each batch
  • Third-party authoritative institution test report customized as needed (may involve additional costs and lead time)
  • Product Safety Data Sheet (SDS), which covers complete ecotoxicological information

Application Recommendations (Environmental Compliance Perspective)

If you have clear requirements for environmental compliance in your end formulations (such as meeting REACH regulations for export to the EU, complying with EC 648/2004 for detergents, or applying for the EU Ecolabel), MOA-9, as a commonly used fatty alcohol polyoxyethylene ether surfactant, can generally meet the basic requirements under the above regulatory frameworks. However, it is still recommended that:

  • Confirm with Guoli Chemical whether the product has completed REACH registration
  • Request biodegradability test data (OECD 301 series methods) to confirm whether the ultimate biodegradation rate is ≥60% (readily biodegradable standard) or meets specific labeling requirements
  • Pay attention to the residual levels of 1,4-dioxane and ethylene oxide (by-product control), especially when used in cosmetics or personal care products, to comply with corresponding limits

Precautions

  • Even if the product itself is biodegradable, the waste liquid after use must be treated by a wastewater treatment system to meet discharge standards and must not be directly discharged into environmental water bodies
  • The storage and use areas of the product should be equipped with leak containment facilities to prevent accidental leakage from contaminating soil and water sources
  • Waste packaging and product residues should be recycled or disposed of by qualified professional waste treatment agencies
  • For specific methods and costs of obtaining test reports, please directly consult the Guoli Chemical sales team. There is no online report download portal in the database.
