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.
| Parameter | Value | Description |
|---|---|---|
| Biodegradability | Excellent | Can be degraded by microorganisms, not prone to persistent accumulation in the environment (from Guoli Chemical product application instructions) |
| Aquatic toxicity classification | H412 | Harmful to aquatic life with long-lasting effects (from product safety data sheet) |
| Heavy metals (as Pb) | ≤10 mg/kg | Meets conventional chemical product limit requirements |
| Arsenic content | ≤2 mg/kg | Strictly controlled, at low level |
| Acute oral toxicity (rat LD₅₀) | >2000 mg/kg | Low acute toxicity |
| Active matter content | ≥99.0% | High purity, few by-products |
| Free alcohol content | ≤2.0% | Strict control of unreacted raw materials |
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:
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:
