Castor Oil Polyoxyethylene Ether EL-40 (PEG-40 Castor Oil) is a non-ionic surfactant. Although its chemical properties are relatively mild, according to the GHS classification criteria, this product is classified as a skin irritant (Category 2) and eye irritant (Category 2), and also hazardous to aquatic life with long-lasting effects (Category 3). The signal word for the product is "Warning" and the hazard pictogram is GHS07 (exclamation mark). This means that standardized operating procedures must be established during use, and care should not be neglected simply because the product is non-flammable and not highly toxic.
In practical applications, the risks of this product are mainly reflected in three aspects: First, direct contact can cause skin redness, pain, and other irritation reactions (H315); second, splashing into the eyes can lead to severe eye irritation and discomfort (H319); third, if discharged directly into water bodies without treatment, it will cause long-term chronic harm to aquatic ecosystems (H412). Therefore, safety protection and environmental management are indispensable regardless of the application scenarios, such as textile dyeing and printing, pesticide formulations, paint production, or daily chemical product manufacturing.
| Exposure Route | First Aid Treatment |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and flush the affected area with plenty of running water and soap for at least 15 minutes. If irritation symptoms (such as redness, pain) persist, seek medical attention immediately. |
| Eye Contact | Immediately lift the eyelids and rinse gently with plenty of running water or saline solution for at least 15 minutes. If contact lenses are worn and can be easily removed, remove them early during the rinse. Do not interrupt the rinsing process, and seek medical attention immediately. If eye irritation persists, repeatedly consult a doctor. |
| Inhalation | Quickly move the affected person to fresh air, maintain an open airway and body temperature. If breathing discomfort occurs, trained personnel should administer medical oxygen. If breathing stops, immediately perform artificial respiration and call emergency services. |
| Ingestion | Do NOT induce vomiting. If the victim is conscious, rinse the mouth thoroughly with water, and do not give anything by mouth. Immediately seek professional medical help and show the product container or Safety Data Sheet to the doctor. |
In case of a spill, immediately isolate the spill area and non-emergency personnel should evacuate quickly. Responders must wear rubber gloves, chemical goggles, and protective clothing. Prevent the spill from entering soil, sewers, surface water, or groundwater systems. Cover and absorb with inert absorbent materials such as sand, vermiculite, then collect in sealed chemical waste containers and dispose of according to hazardous waste regulations.
Waste chemicals and contaminated containers must be disposed of in accordance with local, national, and international environmental regulations. It is recommended to send them to an approved chemical waste treatment facility for high-temperature incineration. Do not discharge the product or its residues into municipal sewage systems or natural water bodies.
Although this product is not classified as a flammable or explosive liquid, it can support combustion in a fire environment. Use carbon dioxide, dry chemical, foam, or water spray for firefighting. Firefighters should wear self-contained positive-pressure breathing apparatus and full protective clothing, and cool containers exposed to flames to prevent rupture. Thermal decomposition or combustion may produce carbon monoxide, carbon dioxide, and irritating fumes, which must be avoided from inhalation.
