Stearic acid polyoxyethylene ether SG-6 (PEG-6 Stearate) has overall high safety; toxicological data shows its acute oral toxicity LD50 > 2000 mg/kg (rat), classified as low toxicity; it is non-irritating to skin (rabbit patch test PII < 0.5), and the skin sensitization rate is 0%, with no sensitization. However, it is particularly noteworthy that rabbit tests indicate the product causes mild reversible irritation to eyes (manifested as conjunctival congestion and edema), which can recover within a few days, but chemical safety goggles should still be worn during operation.
In terms of physicochemical hazards, this product is non-flammable with a closed-cup flash point > 150°C, not igniting in the presence of open flames, and has a low fire risk. However, if thermally decomposed, it may produce carbon monoxide, carbon dioxide, and other irritating or toxic fumes. Therefore, it must be kept away from heat sources and stored in a well-ventilated area. Additionally, if dust is generated during operation, it should be controlled, and general dust explosion prevention measures should be implemented.
From an ecological safety perspective, this product is readily biodegradable (OECD 301B, 28-day degradation rate > 60%), has low toxicity to aquatic organisms (fish 96h LC50, daphnia 48h EC50, algae 72h ErC50 all > 100 mg/L), and has no bioaccumulation potential, making it an environmentally friendly product. In case of leakage, it should still be prevented from entering sewers, waterways, or soil. Absorb with inert materials such as sand or vermiculite and dispose of in accordance with local regulations.
| Safety Aspect | Specific Requirements |
