The environmental compliance of the degreasing powder AR-815 (special cleaning powder for drill bits) needs to be understood from two aspects: formula compliance and waste treatment. According to the Guoli Chemical product database, this product is formulated with sodium carbonate, sodium metasilicate pentahydrate, sodium tripolyphosphate, fatty alcohol polyoxyethylene ether, and sodium dodecylbenzenesulfonate. These surfactants are biodegradable and do not contain substances of very high concern (SVHC) under EU REACH regulations or ozone-depleting substances (ODS) prohibited by international conventions. The formula itself meets current green chemical raw material access requirements.
It is particularly important to note that the 1% aqueous solution of this product has a high pH value of 12.0–13.5, making it strongly alkaline. The high pH has acute and chronic inhibitory effects on aquatic organisms. Therefore, the washing tank wastewater must not be directly discharged into municipal pipelines or natural water bodies without thorough treatment. The correct treatment process is as follows: First, the wastewater must be neutralized by adding acid (such as dilute sulfuric acid or dilute hydrochloric acid) to adjust the pH to the legal discharge standard range of 6–9. If necessary, flocculation and sedimentation should be used to remove washed-off oils and metal soap scum. Then, a sample should be taken for testing to confirm that key indicators such as COD, total phosphorus, and pH meet the standards before being discharged into the pipe network.
Regarding the test report, the current Guoli Chemical product database does not archive third-party environmental test reports for this product (such as VOC content, biodegradability rate reports, or ROHS/REACH test reports). As an industrial B2B chemical supplier, Guoli Chemical can provide corresponding quality inspection reports (COA) or commission third parties for specific project tests based on customer needs and procurement batches. However, such documents are usually not directly available for download on the website.
If you are only concerned about whether the formula contains phosphorus before purchase: This product uses sodium tripolyphosphate as a water softener and dispersant, so it has a certain amount of phosphorus content. If your factory is located in a region with strict total phosphorus discharge limits (such as the Taihu Lake basin, Dianchi Lake basin, and other ecologically sensitive areas), please consult Guoli Chemical in advance for phosphorus-free alternatives or confirm the discharge limits accepted by the local wastewater treatment plant to avoid exceeding emission standards.
