Polyethylene Glycol Distearate 400DS performs excellently in terms of environmental compliance. According to authoritative data from the product safety data sheet, this product is readily biodegradable under aerobic conditions and complies with the OECD 301 series of ready biodegradability standards, meaning it can be rapidly decomposed by microorganisms in natural water environments without causing long-term environmental accumulation. Meanwhile, its octanol\/water partition coefficient (log Pow) is low, indicating low bioaccumulation potential, and it will not bioaccumulate or magnify through the food chain.
In terms of aquatic ecotoxicity, acute toxicity data for fish, crustaceans, and algae show that the median effective concentration (EC50\/LC50) is greater than 100 mg\/L, classifying it as a substance with low toxicity to aquatic organisms. Under predicted use and discharge conditions, it has no inhibitory effect on microorganisms in wastewater treatment plants and will not interfere with the normal operation of biochemical wastewater treatment systems. Overall, this product meets the requirements of modern green chemistry and sustainable development.
Regarding test reports, as the manufacturer, Guoli Chemical typically provides Certificates of Analysis (COA) with each batch, covering routine physical and chemical indicators such as appearance, acid value, and saponification value. If you require third-party environmental compliance test reports (such as OECD 301 biodegradability test reports, aquatic toxicity test reports, etc.), it is recommended to directly contact the sales or technical department of Guoli Chemical to confirm whether existing third-party test reports are available, or to arrange for special testing.

Based on the above environmental characteristics, Polyethylene Glycol Distearate 400DS is very suitable for use in downstream product formulations with strict environmental standards, including personal care products, household detergents, and other fields. When exporting to markets with high chemical environmental compliance requirements such as the EU and North America, the product's ready biodegradability and low eco-toxicity also help formulations pass reviews under regulations like REACH.
