According to the Safety Data Sheet from Guoli Chemical, alkali-resistant penetrant AEP (alcohol polyoxyethylene ether phosphate, CAS No. 68439-39-4) is classified under GHS as Skin corrosion/irritation Category 2 and Serious eye damage/eye irritation Category 2. This means it poses clear health risks upon direct contact, causing skin irritation (H315) and serious eye irritation (H319). Although the product is not flammable or explosive, combustion or thermal decomposition may produce toxic or irritating fumes such as carbon monoxide and carbon dioxide, which are harmful to the respiratory tract.
In terms of environmental impact, this product is classified as Hazardous to the aquatic environment - Acute hazard Category 3 (H402), meaning it is harmful to aquatic life. The phosphate ester group in its structure may pose a local eutrophication risk in natural water bodies. Therefore, it is strictly necessary to avoid direct discharge of the product or its wastewater into sewers, drains, or natural waters. All industrial wastewater must be treated to meet standards before discharge.
| Item | Parameter/Description |
|---|---|
| GHS Hazard Category | Skin corrosion/irritation Category 2; Serious eye damage/eye irritation Category 2; Hazardous to the aquatic environment - Acute hazard Category 3 |
| Signal Word | Warning |
| Skin hazard (H315) | Causes skin irritation — contact may cause redness, stinging, or burning sensation |
| Eye hazard (H319) | Causes serious eye irritation — splash into eyes may cause pain, tearing, blurred vision |
| Inhalation risk | Combustion or thermal decomposition products may contain toxic fumes such as carbon monoxide and carbon dioxide |
| Aquatic toxicity (H402) | Harmful to aquatic life — may cause short-term toxic effects on aquatic organisms such as fish, daphnia, and algae |
| Biodegradability | Belongs to phosphate ester surfactants, with some biodegradability, but direct discharge still poses risks |
Operators should receive special training and strictly follow operating procedures. The work area must be well-ventilated. Wear chemical-resistant gloves, protective clothing, eye protection, or face shield (P280) to avoid any direct contact. Eyewash stations and emergency showers should be available in the workplace. Wash skin thoroughly after handling (P264). Store away from heat sources, acids, oxidizers, and food items. Recommend using polyethylene or stainless steel alkali-resistant containers, maintaining temperature between 5°C and 40°C.
In case of skin contact, immediately remove contaminated clothing and rinse thoroughly with plenty of running water and soap. In case of eye contact, rinse immediately with plenty of running water or saline solution for at least 15 minutes and seek medical attention immediately (P305+P351+P338). Collect leakage using inert absorbent materials such as dry sand or vermiculite into a closed container. Dispose of waste according to regulations (P501). Do not flush into drains.
