XPO-5 tristyrylphenol polyoxyethylene ether ammonium sulfate performs well in environmental compliance. According to ecotoxicological data in the product database, this product is readily biodegradable. Tested according to OECD 301B standard, the 28-day biodegradation rate exceeds 70%, meeting the criteria for a "readily biodegradable" substance, meaning it will not persist or accumulate in the natural environment for a long time.
In terms of aquatic ecotoxicity, XPO-5 exhibits low toxicity to aquatic organisms: the 96-hour median lethal concentration (LC₅₀) for zebrafish is greater than 100 mg/L, and the 48-hour median effect concentration (EC₅₀) for Daphnia magna is also greater than 100 mg/L. These values are far above conventional environmental risk thresholds, indicating a low risk to aquatic ecosystems under normal use and discharge conditions.
Regarding test reports, the product database does not currently store specific third-party test report documents. For actual COA (Certificate of Analysis), SGS test reports, RoHS/REACH compliance statements, etc., please directly contact Guoli Chemical's sales manager or technical customer service. They can provide batch-specific quality test reports and environmental compliance documentation according to your specific needs.
