Stearic Acid Polyoxyethylene Ether SG-10 meets environmental protection regulations and is an environmentally friendly nonionic surfactant that is readily biodegradable and has low aquatic toxicity; for the test report, it is recommended to contact Guoli Chemical customer service directly to obtain the official version.

Detailed Explanation

Stearic Acid Polyoxyethylene Ether SG-10 performs well in terms of environmental performance. According to the OECD 301B standard test, the biodegradation rate of this product exceeds 60% within 28 days, making it a readily biodegradable substance that can be effectively degraded in conventional wastewater treatment systems without long-term accumulation in the environment. Additionally, its toxicity to aquatic organisms is very low, with a 96-hour acute fish toxicity LC50 greater than 100 mg/L, indicating a minor impact on aquatic ecosystems.

From a regulatory compliance perspective, this product meets current environmental protection requirements. Its toxicological data are also favorable: acute oral toxicity is classified as low toxicity (rat LD50 > 5,000 mg/kg), and the Ames test and in vitro mammalian cell chromosome aberration test are both negative, showing no genotoxicity risk. These data collectively indicate that SG-10 is a surfactant product with high safety and eco-friendliness.

However, environmental protection operational norms must still be followed during product use and disposal. It is strictly prohibited to discharge large quantities of the product directly into water bodies, soil, or sewers. It should be treated through standardized wastewater treatment or waste disposal processes to avoid local high concentrations that may impact water bodies.

Environmental Assessment Conclusion

  • Biodegradability: Readily biodegradable, meeting the basic requirements for environmentally friendly surfactants
  • Aquatic Toxicity: Low toxicity, posing minimal risk to aquatic ecosystems
  • Bioaccumulation: Does not accumulate in the environment
  • Regulatory Compliance: Meets current environmental protection regulations

Regarding Test Reports

As a regular chemical manufacturer, Hai'an County Guoli Chemical Co., Ltd. conducts strict quality inspections on all products before shipment. To obtain the official Certificate of Analysis (COA), Material Safety Data Sheet (MSDS), or third-party environmental test report, it is recommended to contact us through the following methods:

  • Contact Guoli Chemical's sales department or technical support team directly, providing the specific batch number to request the corresponding batch's test report
  • Specify the required test items and the purpose of the report (e.g., customer audit, environmental review), so the staff can provide the most suitable documents

Notes

  • The above ecotoxicological data are based on standard product tests; slight variations may exist between batches. Please refer to the actual COA shipped with the product
  • Although the product itself is biodegradable, industrial wastewater must be treated to meet discharge standards before release, and cannot be directly discharged into water bodies
  • Waste products and containers should be disposed of by qualified entities in accordance with national and local regulations, with incineration or sanitary landfill as preferred methods
