The polyethylene glycol PEG-300 (CAS No.: 25322-68-3) produced by Haian Guoli Chemical Co., Ltd. exhibits excellent environmental compliance. According to the product's ecotoxicological data, this product meets internationally recognized standards in key environmental indicators such as aquatic toxicity, biodegradability, and bioaccumulation, making it an environmentally friendly chemical product.
In terms of biodegradability, PEG-300 meets the OECD (Organisation for Economic Co-operation and Development) criteria for ready biodegradability and is classified as an easily biodegradable substance. This means that in the natural environment, it can be rapidly decomposed by microorganisms and will not persist in soil or water bodies. Additionally, its octanol/water partition coefficient (log Kow) is very low, indicating no bioaccumulation or biomagnification effect, so it will not accumulate in organisms through the food chain, making it safe and reliable for the ecosystem.
Regarding aquatic ecotoxicity, PEG-300 exhibits low toxicity or is essentially non-toxic to fish (LC50 > 1000 mg/L, 96 hours), daphnia (EC50 > 500 mg/L, 48 hours), and algae (EC50 > 100 mg/L, 72 hours). At typical industrial discharge concentrations, it does not inhibit biological wastewater treatment systems and does not deplete dissolved oxygen in water bodies.
| Environmental Indicator | Data | Evaluation |
|---|---|---|
| Fish Acute Toxicity (LC50, 96h) | > 1000 mg/L | Essentially non-toxic to fish |
| Daphnia Acute Toxicity (EC50, 48h) | > 500 mg/L | Low toxicity to aquatic invertebrates |
| Algal Growth Inhibition (EC50, 72h) | > 100 mg/L | Low toxicity to algae |
| Biodegradability | Meets OECD ready biodegradability criteria | Easily biodegradable |
| Bioaccumulation (log Kow) | Very low | No bioaccumulation |
| Environmental Persistence | Non-persistent organic substance | Does not persist in the environment |
| Impact on Sewage System | No inhibition (at typical concentrations) | Compatible with sewage systems |
Given the excellent environmental characteristics of PEG-300, this product is particularly suitable for industries with strict environmental requirements: in the pharmaceutical industry, when used as a solvent for injections or as an ointment base, its low toxicity and easy degradability ensure drug safety; in the daily chemical industry, as a humectant and lubricant, it complies with increasingly stringent environmental regulations for personal care products; in the pesticide field, as an emulsifier and spreading agent, it will not cause persistent pollution to farmland soil and water bodies.
Regarding specific environmental test reports (e.g., biodegradability test reports, ecotoxicity test reports, RoHS/REACH compliance statements, etc.), the current product database does not include relevant test report files. It is recommended that you contact the business department or technical support team of Haian Guoli Chemical Co., Ltd. directly. They can provide batch-specific quality inspection reports (COA), MSDS safety data sheets, and third-party environmental test reports according to your specific needs. Commonly available report types include: product quality inspection certificates, SGS test reports, REACH compliance statements, RoHS test reports, etc. If you need assistance in contacting them, please also let us know your specific application and region so that we can provide more precise service.
