The antistatic agent MOA3PK-70 (fatty alcohol polyoxyethylene (3) ether phosphate potassium salt) is not classified as an acutely toxic substance under the GHS classification system. The oral LD50 value in rats is greater than 2000 mg/kg, indicating low acute oral toxicity, which does not meet the acute toxicity classification criteria for hazardous chemicals. However, this does not mean its potential health risks can be ignored—the product is explicitly classified as a skin irritant (Category 2, H315) and serious eye irritant (Category 2A, H319). In routine operations, direct skin contact can cause irritation reactions such as dryness and redness; if splashed into the eyes, it can lead to pain, tearing, and conjunctival congestion.
From an environmental perspective, MOA3PK-70 is currently not classified as an environmentally hazardous substance under the GHS system, nor is it listed as a persistent organic pollutant or a highly ecotoxic substance. However, as a surfactant containing a phosphate ester structure, its large-scale discharge may still impose a certain burden on aquatic ecosystems, particularly in terms of potential indirect effects on water eutrophication. Therefore, although environmental risk labeling is not mandatory under regulations, enterprises should adhere to the principle of responsible care and strictly control the compliance discharge of industrial wastewater.
The product has a flash point (closed cup) greater than 100°C, is not classified as a flammable liquid, and poses no significant combustion or explosion risk under normal storage and processing temperatures. Overall, its physicochemical hazards are low. In summary, the safety risks of MOA3PK-70 are manageable—the key lies in standardized operations, proper protection, and proper waste disposal, enabling safe production and application.
| Assessment Item | Classification/Data | Description |
|---|---|---|
| Acute Oral Toxicity | LD50 (rat) > 2000 mg/kg | Does not meet acute toxicity classification criteria; low toxicity |
| Skin Irritation | Category 2 (H315) | Causes skin irritation, may lead to dryness and redness |
| Eye Irritation | Category 2A (H319) | Causes serious eye irritation, may lead to pain and tearing |
| Flammability | Not classified as a flammable liquid | Closed cup flash point > 100°C |
| Environmental Hazard Classification | Not classified as an environmentally hazardous substance | Still need to prevent large spills into water bodies and soil |
Personal Protection: Chemical safety goggles or face shields and nitrile rubber gloves resistant to chemical corrosion must be worn during operation; wear impermeable work clothing to avoid exposed skin contact. The work area should have good ventilation, and eating, drinking, and smoking are prohibited.
Storage Management: Store sealed in a cool, dry, well-ventilated warehouse. Recommended container materials include stainless steel, polyethylene, or polypropylene, and keep away from strong oxidizers and strong acids/bases. Leak-proof trays should be placed in the storage area, and the floor should be treated for anti-seepage.
Waste Disposal: Industrial wastewater containing MOA3PK-70 must be treated through the plant's wastewater treatment system to meet standards before discharge. Do not discharge directly into municipal stormwater drains or natural water bodies. Used empty containers should be properly disposed of as industrial solid waste.
