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.
