The environmental friendliness of Polyoxyethylene Stearate SG-9 (PEG-9 Stearate) is mainly reflected in its excellent biodegradability. According to the environmental information in the Guoli Chemical product database, the product was tested under OECD 301B standard, with a biodegradation rate greater than 60%, classifying it as "readily biodegradable." This means that in the natural environment, it can be quickly broken down by microorganisms into harmless substances such as water and carbon dioxide, without long-term persistence and accumulation in the ecosystem.
However, it must be noted that this product has some acute toxicity to aquatic organisms. The database shows that its fish acute toxicity LC50 (96h) is in the range of 10–100 mg/L, placing it in the "harmful to aquatic life" category. Therefore, despite its biodegradability, the waste liquid after use must be strictly treated in accordance with regulations. Untreated wastewater must not be directly discharged into soil, drains, sewers, and natural waterways to prevent immediate harm to local aquatic life.
In terms of product safety classification, Polyoxyethylene Stearate SG-9 is a non-hazardous substance and is not listed under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Its acute toxicity is very low (rat oral LD50 > 2000 mg/kg), and the Ames mutagenicity test result is negative. Overall, the product itself is low-toxicity and easily biodegradable. Its environmental compliance depends primarily on whether the treatment of the "three wastes" (especially wastewater) meets local environmental regulations.
| Indicator Item | Specification/Data | Environmental Significance and Description |
|---|---|---|
| Biodegradability | Readily biodegradable (>60%, OECD 301B method) | Core environmental indicator, showing the product can quickly decompose in the environment and is not persistent. |
| Ecotoxicity (LC50, Fish, 96h) | >10 – 100 mg/L | Clearly indicates that high concentrations of the product are harmful to aquatic organisms in case of spillage, requiring strict control of water pollution. |
| Total Heavy Metals | ≤ 10 mg/kg | Very low heavy metal content, meeting the common standards for green chemical products. |
| Arsenic Content (As) | ≤ 2 mg/kg | Strict control of harmful element content, reducing potential risks to soil and water bodies. |
| Hazard Classification | Non-hazardous, not listed under GHS classification | Meets the convenience and safety standards for non-hazardous chemicals in transportation, storage, and routine handling. |
To maximize the environmental advantages of the product and avoid environmental risks, it is recommended that you during use:
Regarding your request to "provide a test report," Guoli Chemical can provide a Certificate of Analysis (COA) tied to its unique production batch at the time of shipment. The COA contains actual measured data for key indicators such as active content, pH value, acid value, and heavy metals as listed in the above technical parameter table. Additionally, as a regulatory document, we can also provide a detailed Safety Data Sheet (SDS), where Section 12 details ecological toxicology and degradation environmental information. To request a COA or SDS for a specific batch, please contact the Guoli Chemical Sales Department and provide your product batch number.
