The alkali-resistant penetrant AEP (CAS No.: 68439-39-4), in terms of environmental compliance, is classified as Hazardous to the aquatic environment - Acute hazard category 3 according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) and the Safety Data Sheet (SDS). Its hazard statement includes H402 (Harmful to aquatic life), meaning that if the product is discharged directly into water bodies without treatment, it may cause harm to aquatic ecosystems. However, it should be noted that this classification is very common among industrial surfactants, and it does not mean the product is banned or highly toxic. The key lies in proper wastewater treatment after use.
From a regulatory compliance perspective, as a phosphate ester anionic surfactant, the alkali-resistant penetrant AEP contains phosphorus in its molecular structure. The product itself may produce toxic or irritating fumes such as carbon monoxide and carbon dioxide during high-temperature or combustion decomposition, but it is not flammable or explosive and is not classified as dangerous goods. To determine whether it meets specific environmental standards (such as OEKO-TEX, ZDHC, Bluesign, etc. for the textile industry), the actual end-use and the customer's specific certification requirements must be considered.
Regarding the test report, Guoli Chemical provides a routine Certificate of Analysis (COA) for the alkali-resistant penetrant AEP, covering key technical indicators such as active content (≥98.0%), pH value (1% aqueous solution 5.0~7.0), acid value (150~180 mgKOH/g), and free phosphoric acid (≤5.0%). However, for specific third-party environmental test reports, such as biodegradability testing (OECD 301 series), SGS hazardous substance screening reports, or RoHS/REACH compliance declarations, there are no ready-to-download electronic documents in the company database. Please contact the Guoli Chemical sales and technical team to obtain them separately based on purchase requirements.

When using the alkali-resistant penetrant AEP in areas with strict environmental discharge requirements, it is recommended to take the following measures:
Operators should strictly follow safety operating procedures, wear chemical protective gloves, protective clothing, and eye protection (P280), and avoid releasing the product into the environment. In case of leakage, absorb with inert absorbent materials (such as dry sand, vermiculite) and dispose of as hazardous waste (P501). Do not flush into drains.
