According to China's GHS classification standards, Tween-80 (CAS: 9005-65-6) is classified as a non-hazardous substance or mixture, and under normal use conditions, it poses no significant harm to human health or the environment. This product is a classic non-ionic surfactant, and its raw material composition determines that it has a certain degree of biodegradability. When used at recommended concentrations and discharged properly, it will not cause significant toxic effects on aquatic ecology.
From an ecotoxicological perspective, Tween-80 has low toxicity to aquatic organisms, with no significant risk of ecological toxicity accumulation at recommended application concentrations. However, special attention should be paid to the fact that if a large spill occurs into water bodies, the product may form a physical oil film on the water surface, hindering oxygen exchange, thereby indirectly causing local hypoxia. Therefore, during use, environmental regulations must be strictly followed, and untreated materials must not be directly discharged into drainage systems or natural water bodies.
Unlike some surfactants containing phosphorus or heavy metals, Tween-80 does not involve components that pose persistent risks to the environment during production and use. It aligns with the current development trend of green chemistry and human/environment-friendly auxiliaries, and has been widely recognized and long-term applied in fields with strict environmental and safety requirements, such as pharmaceuticals, food, and cosmetics.
| Environmental Indicator | Data/Description |
|---|---|
| GHS Hazard Classification | Non-hazardous substance or mixture |
| Aquatic Toxicity | Low toxicity (no significant ecological toxicity at normal use concentration) |
| Biodegradability | Biodegradable (based on raw material composition) |
| Heavy Metal Content | ≤10 ppm |
| Arsenic Content | ≤2 ppm |
| Phosphorus Content (free phosphoric acid/combined phosphorus) | None |
| pH Value (1% or 5% aqueous solution) | 5.0–7.0 |
| Risk of Large Spills | May form a physical film on the water surface, affecting oxygen exchange |
Note: The above data is from Guoli Chemical product database.
Routine factory inspections of this product cover core indicators such as appearance, active content (≥97%), acid value (≤2.0), saponification value (45–55), hydroxyl value (65–80), moisture (≤3.0%), pH value (5.0–7.0), heavy metal and arsenic content. Currently, the above parameters have been stated in our communication, but the database does not yet contain electronic versions of independent third-party environmental test reports (such as RoHS, REACH, biodegradability test reports, acute aquatic toxicity reports, etc.) that can be directly downloaded.
If you need a formal stamped Certificate of Analysis (COA) or specific environmental compliance test reports, it is recommended to directly contact Guoli Chemical's sales or quality control department. They can provide corresponding batch test data and compliance documents based on your specific application (e.g., REACH compliance statement required for export to the EU, pharmaceutical excipients meeting pharmacopoeia standards, etc.).
