Emulsifier FM (triethanolamine monooleate, CAS No.: 2717-15-9) is classified as Skin Sensitizer Category 1 under the GHS classification system, with the signal word "Warning." Its hazard statement (H317) clearly states: May cause an allergic skin reaction. This means that even short-term contact can cause allergic symptoms such as redness, itching, or rash, and repeated long-term exposure may increase sensitivity.
In addition to the risk of skin sensitization, this product can also cause serious eye irritation, and splashing into the eyes can cause discomfort and damage. Although the GHS classification label does not require a pictogram for this product, this by no means implies that the risk can be ignored—in chemical operations, "absence of a pictogram" does not mean "no danger." Especially for sensitizing substances, allergic reactions often manifest only after repeated exposure and have a certain degree of concealment and latency.
Overall, the safety risks of emulsifier FM are concentrated in two pathways: skin contact and eye contact. The risks of inhaling vapors and accidental ingestion are relatively low but still require prevention. In daily operations, good personal protection and environmental control can effectively manage the above risks.
| Accident Type | Emergency Steps |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and rinse skin with soap and plenty of running water for at least 15 minutes. If irritation or rash develops, seek medical attention immediately. Contaminated clothing must be washed before reuse. |
| Eye Contact | Immediately lift eyelids and rinse eyes continuously with plenty of water or saline for at least 15 minutes. If wearing contact lenses and they can be easily removed, remove them and continue rinsing. If irritation persists, seek medical attention. |
| Inhalation of Vapors | Quickly move the person to fresh air and maintain an open airway. If breathing is difficult, give oxygen; if breathing stops, perform artificial respiration immediately and seek medical attention. |
| Ingestion | Do NOT induce vomiting (unless directed by medical personnel). Rinse mouth with water and seek medical attention immediately. Never give anything by mouth to an unconscious person. |
| Spill Containment | Small spills: Absorb with inert absorbent materials (e.g., sand, vermiculite), collect in a sealed container, and dispose of as hazardous waste. Large spills: Construct dikes to control the source, cover with foam to suppress vapors, and transfer to dedicated containers with explosion-proof pumps for recovery. Prevent entry into sewers, surface water, and groundwater. |
| Fire Fighting | Suitable extinguishing media: carbon dioxide, dry powder, foam, water spray. Avoid direct stream of water into the container to prevent splashing. Firefighters should wear self-contained breathing apparatus and full-body protective clothing. |
In practical applications, emulsifier FM is recommended to be added in a well-ventilated compounding area. Using closed pipeline transfer or pump feeding can minimize personnel exposure. For industrial applications such as metalworking fluids, textile auxiliaries, and pesticide formulations, it is recommended to fully consider the safety protection conditions of operators during the formulation design stage and optimize the feeding process to reduce exposure risks. If used in laboratory development of cosmetic formulations, since this product is a skin sensitizer, the final product must undergo adequate safety evaluation and patch testing.
