According to Guoli Chemical's product safety technical data, polypropylene glycol PPG-600 (CAS No.: 25322-69-4) demonstrates good environmental performance: acute oral toxicity LD₅₀ > 2,000 mg/kg, classified as a low-toxicity substance; it exhibits low toxicity to aquatic organisms and has low bioaccumulation potential. The GHS classification assessment indicates that this product is not classified as a hazardous substance or mixture and does not require hazard classification under GHS standards. However, it should be noted that although the product itself has low environmental hazards, it is still necessary to strictly avoid direct discharge of large quantities of untreated product into water bodies or soil. Waste disposal should comply with local, provincial, and national regulations, and it is recommended to carry out incineration or recycling at qualified waste treatment facilities.
Regarding test reports, Guoli Chemical's product database currently does not provide independent third-party test reports online. Official product test reports (such as ROHS, REACH, Halogen, Heavy Metals, etc. issued by third-party organizations like SGS or CTI) are usually issued with batch products or provided upon customer request. It is recommended that you directly contact Guoli Chemical's sales or technical service department, specifying the required test items (e.g., heavy metal content, hazardous substance limits, biodegradability, etc.), to obtain the corresponding batch's formal Certificate of Analysis (COA).
The following are the complete technical parameters related to environmental protection and safety for polypropylene glycol PPG-600 recorded in Guoli Chemical's database, where heavy metal content, arsenic content, and other indicators can serve as important references for environmental compliance.
