XPO-5 tristyrylphenol polyoxyethylene ether ammonium sulfate is generally safe. Toxicological data shows that the rat oral LD₅₀ is greater than 2000 mg/kg, classifying it as a low-toxicity substance; it is non-irritating to the skin (Draize test, neat, rabbit, 4h) and non-sensitizing (negative in guinea pig maximization test). The rabbit eye irritation index is ≤1.0, judged as non-irritating to eyes, though mild discomfort may still occur. In terms of ecotoxicology, this product is of low toxicity to aquatic organisms (zebrafish 96h LC₅₀ > 100 mg/L) and is readily biodegradable (OECD 301B, >70% degradation in 28 days), demonstrating good environmental friendliness.
The core risks during handling are: upon combustion or high-temperature decomposition, it may produce toxic fumes including carbon monoxide, carbon dioxide, sulfur oxides (SOₓ), and ammonia, so it must be kept away from heat sources and open flames. Additionally, it may undergo violent reactions with strong oxidizing agents; therefore, storage and handling must strictly avoid mixing with such substances. Although the product itself is not flammable or explosive, in the event of a fire, firefighters must wear self-contained positive-pressure respirators and full fire-resistant and chemical-protective suits for disposal.
In daily operations, it is recommended to wear chemical safety goggles, protective clothing, and chemical-resistant gloves; maintain good ventilation in the work area; and thoroughly wash skin after handling. Eating, drinking, or smoking is prohibited at the work site. The product should be stored in a cool (5–40°C), dry, well-ventilated dedicated storage area, with containers kept sealed, and separated from strong oxidizing agents, strong acids, strong bases, and away from food and feed areas.
