Answer

MOA-5/AEO-5 is a readily biodegradable nonionic surfactant that meets general environmental requirements. Its content of heavy metals and other harmful impurities is extremely low, making it an environmentally friendly additive.

Detailed Explanation

MOA-5/AEO-5 (C12-14 fatty alcohol polyoxyethylene (5) ether) is produced by addition polymerization of natural fatty alcohols and ethylene oxide. Its linear alkyl structure endows the product with excellent biodegradability, allowing it to decompose rapidly in the natural environment after use without causing persistent organic pollution. According to data from the Guoli Chemical product database, the heavy metal content in this product is ≤10 mg/kg, and the arsenic content is ≤2 mg/kg, far below the hazardous substance limits for conventional industrial chemicals, posing a low risk to aquatic ecosystems.

From a regulatory perspective, the AEO series (fatty alcohol polyoxyethylene ether) is listed as an assessed and permitted traditional nonionic surfactant under the EU REACH regulation, China's "Environmental Management of New Chemical Substances" and "Priority Control Chemicals List". It is neither a persistent organic pollutant (POP) nor a substance of very high concern (SVHC). This product is non-flammable (closed cup flash point >165°C) and is not classified as dangerous goods during transportation, thereby reducing the risk of environmental pollution from physical hazards.

In terms of compliant use, this product only has skin irritation (H315) and eye irritation (H319) and does not carry severe environmental hazard labels such as acute aquatic toxicity or reproductive toxicity. However, it should be noted that although the product itself is biodegradable, as a concentrated surfactant, it should be treated through a wastewater treatment system before discharge to avoid direct release into natural water bodies, which could cause local eutrophication.

Technical Parameters (Environmental Indicators)

Indicator ItemDataEnvironmental Significance
Heavy Metal Content≤10 mg/kgFar below ecotoxicological limits, safe for aquatic life
Arsenic Content≤2 mg/kgMeets strict international limit standards
Active Content≥99%High purity, low impurities, reduces unintended pollution
Moisture Content≤1.0%Low moisture ensures product stability, reduces need for preservatives
Free Alcohol Content≤2%Complete reaction, low residual monomer
Flash Point (Closed Cup)>165°CNon-flammable liquid, reduces VOC emission risk
BiodegradabilityReadily biodegradable (linear fatty alcohol structure)Rapidly degrades in the environment, does not accumulate

Regarding Test Reports

Guoli Chemical currently does not provide directly downloadable third-party environmental test reports (such as SGS, CTI, or Pony testing reports) in its product database. However, as a compliant manufacturer, routine outgoing products are accompanied by a Product Quality Certificate (COA), which includes measured data for key environmental indicators such as heavy metals, arsenic, and moisture.

How to Obtain Official Test Reports:

  • If you need the specific COA for a shipment batch, it can be included with the order, or you can contact the Guoli Chemical sales department to request it.
  • If you need specialized environmental test reports from a third-party authority (such as RoHS, REACH testing, acute aquatic toxicity reports, etc.), you can request this when placing an order. Guoli Chemical will assist in arranging the testing and providing the official report.

Environmental Considerations in Application

  • Although this product is biodegradable, large volumes of wastewater generated after use in industrial cleaning or textile scouring are recommended to be treated through a conventional wastewater treatment plant (coagulation sedimentation or biological aeration) before discharge.
  • When formulating daily chemical or industrial products, this nonionic surfactant can be blended with other green surfactants (such as APG, amino acid-based surfactants) to further enhance the overall environmental profile of the formulation.
  • Discharge at normal usage concentrations (typically 0.1%-1% aqueous solution) can be effectively degraded by microorganisms in municipal wastewater treatment plants. Do not pour high-concentration stock solutions directly into drains or soil.
