The acute oral toxicity LD₅₀ of XPO-4 (Glycerol polyoxyethylene ether oleate) is greater than 5000 mg/kg (rat), which belongs to the low acute toxicity class, and under normal industrial use conditions, the acute hazard to humans is low. This product shows no skin irritation, but according to GHS classification, its main health risk lies in eye irritation (Category 2, H319) — contact can cause serious eye irritation. Based on available data, this product is a non-flammable liquid (flash point > 150°C), with no explosiveness or oxidizing properties, making it relatively safe in terms of physicochemical hazards.
Regarding environmental impact, the biodegradation rate of XPO-4 exceeds 70% (OECD 301B method), classifying it as readily biodegradable and not persistent in the natural environment. However, it should be noted that according to GHS classification, it is harmful to aquatic organisms (Acute Aquatic Toxicity Category 3, H402), with a fish acute toxicity EC₅₀ greater than 100 mg/L. Therefore, untreated waste or residues must not be arbitrarily discharged into soil, waterways, or public drainage systems.
Overall, XPO-4 is a relatively safe industrial auxiliary agent. Under strict adherence to safety operating procedures, proper personal protection (especially eye protection), and appropriate waste disposal, its negative impact on human health and the ecological environment can be effectively controlled.
