Polyethylene glycol PEG-4000/6000 is a nonionic high-molecular polymer. Based on existing product data, its environmental characteristics are mainly reflected in the following aspects: First, according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and EC No 1272/2008 regulations, this product is not classified as a dangerous substance or mixture. Second, its acute oral toxicity LD50 (rat) is greater than 5000 mg/kg, which is classified as practically non-toxic, posing a relatively low risk of direct harm to the ecological environment and human health. In addition, this product has good water solubility and can be gradually biodegraded in the natural environment without causing persistent organic pollution.
It should be noted that PEG-4000/6000 itself is not listed as a key controlled pollutant. However, in large-scale industrial use, when fine dust mixes with air to a certain concentration, there is a risk of dust explosion (dust explosion class St1). Therefore, enterprises need to equip appropriate dust collection and ventilation systems, which is both a production safety requirement and an important part of environmental compliance. During operation, dust should be prevented from escaping into the atmospheric environment.
Regarding the test report you mentioned, there are no directly downloadable environmental test report files (such as RoHS, REACH, biodegradation rate test reports, etc.) in the product database. Test reports usually vary depending on the batch, customer requirements, and target market. It is recommended that you directly contact the sales or quality inspection department of Haian County Guoli Chemical Co., Ltd., specifying the type of report required (such as REACH compliance statement, SGS test report, RoHS test report, biodegradability test report, etc.) to obtain the formal documents for the corresponding batch.

In applications such as pharmaceuticals, daily chemicals, textiles, and papermaking, PEG-4000/6000, due to its low toxicity and good water solubility, can replace some traditional additives that have a higher environmental burden. In wastewater treatment, industrial wastewater containing PEG is recommended to be treated using conventional biochemical treatment processes such as the activated sludge method. Its biodegradable properties help reduce the COD load of the wastewater. In the field of pesticide formulations, when used as a dispersion carrier, it can reduce the use of organic solvents, offering certain green formulation advantages.
