Polypropylene glycol PPG-200 (CAS No.: 25322-69-4) performs well in environmental compliance. According to the safety data in the Guoli Chemical product database, this product has a toxicity classification of "low toxicity" and is not classified as a hazardous substance (not classified as a dangerous substance in GHS classification, only marked as possibly causing eye irritation H319). Its acute toxicity index LD50 (oral, rat) is greater than 2,000 mg/kg, which is in the low acute toxicity range, posing a low risk of direct harm to the ecological environment.
Regarding waste disposal, Guoli Chemical clearly requires: Dispose of through qualified waste treatment agencies in accordance with local regulations, and prohibit discharge into sewers, surface water, or groundwater. This indicates that although the product is not a high-risk chemical, standardized environmental procedures must still be followed during end-of-life disposal. PPG-200 has a relatively low molecular weight (190–210) and has some potential for degradation in the environment, but it is not a rapidly biodegradable substance, so it cannot be directly discharged into natural water bodies.
Regarding test reports, there is no recorded information on third-party environmental test reports such as RoHS, REACH, or SGS in the Guoli Chemical product database. As an industrial intermediate and lubricant raw material, PPG-200 is generally not directly sold to the end consumer market, and its environmental compliance is mainly determined based on toxicological and environmental data in the Safety Data Sheet (SDS). If your downstream application requires a formal environmental test report (e.g., heavy metal content, harmful substance screening, etc.), it is recommended to directly contact the sales or technical department of Hai'an Guoli Chemical Co., Ltd. to confirm whether they can issue a corresponding batch Certificate of Analysis (COA) or commission a third-party testing agency for specific testing.

If you are concerned about the environmental compliance of the product for the following scenarios, it is recommended to take corresponding measures:
Key environmental operation points explicitly required in the database: In case of leakage, contain and prevent entry into sewers or water bodies; discarded empty containers may have product residues and must be properly disposed of, not discarded casually. If a formal environmental test report or compliance statement is needed, please directly contact the technical department of Guoli Chemical to obtain the latest batch documentation.
