Agricultural emulsifier 600 (tristyrylphenol polyoxyethylene ether) is a nonionic surfactant, appearing as a light yellow to brownish yellow viscous liquid at room temperature. Although its acute toxicity is low (rat oral LD₅₀ > 2000 mg/kg, rabbit dermal LD₅₀ > 2000 mg/kg), according to GHS classification, this product falls under Skin Irritation Category 2 (H315), Serious Eye Damage/Eye Irritation Category 2A (H319), Specific Target Organ Toxicity - Single Exposure Category 3 (respiratory irritation, H335), and Aquatic Chronic Toxicity Category 3 (H412). This means that in routine operations, direct skin contact can cause irritation, splashes into the eyes can lead to serious injury, and inhalation of its vapor or aerosol can cause respiratory discomfort.
In application scenarios such as pesticide formulation processing, textile dyeing and printing, and industrial cleaning, this product is often used in combination with other surfactants or solvents. Due to its good compatibility, operators may easily overlook its potential irritation risks. It is recommended to strictly implement protective measures and ensure good ventilation in the workplace during all operations that may involve contact, such as ingredient mixing, feeding, stirring, and packaging.
| Incident Type | Response Measures |
|---|---|
| Skin Contact | Immediately remove contaminated clothing and flush skin thoroughly with plenty of running water and soap for at least 15 minutes. If irritation persists, seek medical attention. |
| Eye Contact | Immediately lift eyelids and flush continuously with plenty of running water or saline for at least 15 minutes. Seek immediate medical attention without delay. |
| Inhalation | Move the person to fresh air immediately and keep the airway clear. If breathing is difficult, administer oxygen; if breathing stops, perform artificial respiration and seek medical attention. |
| Ingestion | Rinse mouth with water. Do NOT induce vomiting. Seek immediate medical attention and show the product container or label. |
| Leakage Treatment | Quickly isolate the leakage area. Wear appropriate PPE, then use inert absorbent materials (e.g., sand, vermiculite, or universal absorbent pads) to contain and absorb the leaking liquid. Collect in a closed container for disposal as hazardous waste. Prevent leakage from entering drains or water bodies. |
Agricultural emulsifier 600 is harmful to aquatic life with long-lasting effects; fish 96h LC₅₀ is in the range of 10–100 mg/L. Therefore, it is strictly prohibited to discharge this product or its wastewater directly into drains, surface water, or groundwater systems. Waste disposal should be entrusted to qualified professional organizations for harmless treatment and must not be discarded with household waste.
In practical applications, when agricultural emulsifier 600 is used as a pesticide emulsifier, textile auxiliary, industrial cleaning agent, or metalworking fluid component, it is recommended to fully consider its safety characteristics during the formulation development stage, optimizing processes to reduce operator exposure opportunities. When compounding, pay attention to compatibility testing with other surfactants to avoid performance degradation or new safety hazards due to improper formulation. Before use, be sure to refer to the product Safety Data Sheet (SDS) and Technical Data Sheet (TDS) for complete physicochemical parameters and toxicological data.
