Agricultural Emulsifier 600 (tristyrylphenol polyoxyethylene ether) is a nonionic surfactant. Under normal industrial use conditions, its acute toxicity is low: the oral LD50 in rats is > 2000 mg/kg, and the dermal LD50 in rabbits is > 2000 mg/kg, so it is not classified as a highly toxic substance. However, this product has significant irritancy to the skin, eyes, and respiratory system. It falls under GHS classification: Skin irritation category 2 (H315), Serious eye damage/eye irritation category 2A (H319), and Specific target organ toxicity—single exposure category 3 (respiratory tract irritation, H335). This means that direct contact or inhalation of its vapors or mists can cause symptoms such as skin redness, eye pain, and respiratory discomfort.
In terms of environmental impact, Agricultural Emulsifier 600 is harmful to aquatic life with long-lasting effects (GHS classification: Aquatic chronic toxicity category 3, H412). Data show that the 96-hour LC50 for fish is in the range of 10–100 mg/L, indicating a non-negligible toxic effect on aquatic ecosystems. If discharged into natural water bodies, it may harm fish, plankton, and other aquatic organisms. Moreover, the product has a certain persistence in the environment, so its effects do not disappear quickly.

When Agricultural Emulsifier 600 is used as a pesticide emulsifier, textile auxiliary, or component in industrial cleaning agents, it should be operated in strictly controlled industrial environments. It is recommended that operators must wear chemical safety goggles, protective gloves, and protective clothing; in poorly ventilated work areas, effective respiratory protective equipment should be provided. Emergency eyewash stations and safety showers should be installed in the workplace, and hands and exposed skin should be thoroughly washed after operation. Eating, drinking, and smoking are strictly prohibited at the worksite.
For storage, the product should be placed in a cool, dry, well-ventilated dedicated warehouse, with temperature controlled between 5–35°C. Containers should be kept tightly closed and away from heat sources, ignition sources, and incompatible materials such as strong oxidizers. The storage area should be equipped with dikes or trays to prevent spill dispersion.
