Polyethylene glycol PEG-200 (CAS No.: 25322-68-3) is explicitly defined as an environmentally friendly nonionic surfactant in the product database of Haian Guoli Chemical Co., Ltd. According to the data in Sections 2 and 8 of its Safety Data Sheet, this product has low ecotoxicity, poses no significant harm to aquatic organisms, and is easily biodegradable, with no expected bioaccumulation in organisms. This means that under normal use and compliant discharge conditions, PEG-200 will not cause persistent pollution to water bodies, soil, or other ecological environments, aligning with the basic environmental protection concepts of green chemistry and sustainable development.
From a toxicological and ecological perspective, PEG-200 has an acute oral toxicity (rat) LD50 greater than 2000 mg/kg, classifying it as a low-toxicity substance; the Ames test result is negative, indicating no genotoxicity; and the skin sensitization test is also negative. These data show that the product poses very low health risks to humans and can be gradually degraded into harmless substances through natural microbial action in the environment, without generating toxic intermediates during degradation. National and local environmental regulations generally recognize such low-toxicity, easily biodegradable nonionic surfactants, and an increasing number of industrial formulations choose PEG series as environmentally friendly alternatives.
| Test Item | Technical Indicator | Environmental Significance |
|---|---|---|
| Ecotoxicity | Low | Safe for aquatic organisms, minimal environmental impact |
| Biodegradability | Easily biodegradable | Naturally decomposes in the environment, does not persist |
| Bioaccumulation | No expected bioaccumulation | Does not accumulate through the food chain |
| Acute Oral Toxicity (Rat) | LD50 > 2000 mg/kg | Low toxicity, low health risk to humans |
| Genotoxicity (Ames Test) | Negative | No mutagenic risk |
| Heavy Metal Content | ≤10 mg/kg | Complies with conventional industrial environmental standards |
| Arsenic Content | ≤2 mg/kg | Strict control of harmful element content |
| Active Content | ≥99% | High purity, reduces potential environmental impact of impurities |
| Moisture Content | ≤0.5% | Stable product, does not generate harmful hydrolysates during storage |
According to the Safety Data Sheet in the Guoli Chemical product database, PEG-200 is already equipped with a complete Material Safety Data Sheet (MSDS/SDS), which includes key environmental and safety data such as ecological information and toxicological information. This product is not classified as a hazardous chemical under national chemical classification standards. The database records detailed toxicological test data (such as acute oral toxicity, skin irritation, skin sensitization, Ames test, etc.), all of which serve as data support for the product's environmental and safety performance.
However, it should be noted that the database does not currently have detailed records of independent environmental test report numbers, issuance dates, or specific certification standards (such as OECD 301 series biodegradation test reports) issued by third-party testing agencies. If you need formal environmental test report documents, it is recommended to directly contact the Guoli Chemical sales or technical team to obtain test certificates issued by qualified testing agencies, or request the Certificate of Analysis (COA) for specific batches, which usually includes actual measured data for environmentally relevant indicators such as heavy metal and arsenic content.
Given the low ecotoxicity and easy biodegradability of PEG-200, this product is highly suitable for formulations with strict environmental requirements, such as green cosmetics, environmentally friendly coatings, bio-based inks, and pharmaceutical excipients. If you are conducting product environmental compliance assessments or environmental certification applications for exported products, you can directly cite the toxicological and ecological data from the above database as support; if you need more authoritative third-party test reports, it is recommended to submit a written request to Guoli Chemical to obtain test documents for specific batches.
