Polyethylene Glycol PEG-600 (CAS Number: 25322-68-3) exhibits good environmental protection characteristics from the perspective of chemical structure and environmental behavior. This product is a nonionic polymer compound. The ether bonds (C-O-C) in the molecular main chain can be slowly degraded in the environment through pathways such as photooxidation and biological enzymatic hydrolysis, ultimately decomposing into carbon dioxide and water. According to the Guoli Chemical product database, the acute oral toxicity LD50 of this product in rats is greater than 2000 mg/kg, belonging to the low toxicity level; it is non-irritating to skin and only slightly irritating to eyes, indicating low direct harm to organisms.
The limits of heavy metals and harmful elements also reflect the environmental attributes of the product. The product quality standard clearly controls the total heavy metal content to ≤20 mg/kg and the arsenic content to ≤2 mg/kg, which are far below the limit requirements for general industrial chemicals, meeting the strict standards for pharmaceutical and cosmetic applications. In terms of waste disposal, Guoli Chemical clearly requires that waste be handed over to licensed waste disposal agencies for incineration or appropriate treatment in accordance with local and national regulations, prohibiting discharge into sewers, waterways, or soil, reflecting the company's emphasis on environmental responsibility.
Regarding test reports, the current Guoli Chemical product database does not include third-party environmental test reports (such as RoHS, REACH, SGS test reports, etc.) for this product. To obtain a formal Certificate of Analysis (COA), Safety Data Sheet (SDS), or specific environmental compliance statements, it is recommended to directly contact the sales department or quality management department of Guoli Chemical, who can provide test data for the corresponding batch according to your specific needs.
| Parameter Name | Specification | Environmental Significance |
|---|---|---|
| Active Content | ≥99% | High purity, few impurities, reducing introduction of harmful by-products |
| Total Heavy Metals | ≤20 mg/kg | Meets heavy metal limit requirements for pharmaceutical and cosmetic grades |
| Arsenic Content | ≤2 mg/kg | Controls harmful elements, ensures safe use |
| Free Alcohol | ≤0.1% | High degree of reaction, very low residual unreacted monomers |
| Acid Value | ≤0.5 mgKOH/g | Neutral pH, reducing corrosiveness and ecotoxicity |
| pH (1% Aqueous Solution) | 5.0~7.0 | Close to neutral, minimal impact on water pH when discharged |
| Flash Point | ≥220℃ | High flash point indicates low volatility, reducing VOC emissions |
| Iodine Value | ≤0.1 | Extremely low unsaturation, chemically stable |
Polyethylene Glycol PEG-600, with its good biodegradability and low ecotoxicity, is particularly suitable for fields with high environmental protection requirements. In the pharmaceutical and personal care industries, its purity and safety indicators already have inherent advantages, making it a preferred choice for green formulations. When used as an emulsifying dispersant in pesticide formulations, the molecular structure will gradually degrade after the solution enters the soil, without long-term accumulation in the environment. When used in the textile and paper industries, it is recommended to equip with wastewater treatment facilities to ensure that the COD of discharged water meets standards.
