According to the safety technical data from the Guoli Chemical Product Database, polypropylene glycol PPG-200 is clearly classified as a low-toxicity, non-hazardous substance. Its acute oral toxicity LD50 (rat) is greater than 2,000 mg\/kg, and under the current GHS classification standard, it is not classified as a hazardous substance. This means that under normal industrial usage conditions, its risk to human health is controllable.
The main potential impacts on the human body are concentrated in local contact: it may cause mild eye irritation (corresponding to H319 warning), and long-term or repeated skin contact may lead to skin defatting and dryness. However, this product has low volatility and a mild nature, making it relatively friendly to production equipment and operating environments. As long as basic safety operating procedures are followed (wearing protective goggles and chemically resistant gloves, maintaining ventilation), risks can be effectively avoided.
In terms of environmental impact, the database explicitly requires prohibition of discharging this product into sewers, surface water, or groundwater. In case of leakage, containment should be implemented to prevent entry into water bodies. Waste disposal should be handled by qualified institutions. The product is a polymer that does not degrade quickly in the environment; therefore, although it is not a highly toxic substance, improper discharge may cause cumulative effects on aquatic ecosystems. Strict control of waste liquid disposal is essential.

PPG-200 is widely used in synthetic lubricants, hydraulic fluids, mold release agents, defoamers, initiators for flexible polyurethane foam, and cosmetic intermediates. In these applications, the product dosage and process conditions are within a safe and controllable range. It is recommended that all application scenarios be equipped with local ventilation, and operators should undergo safety training before starting work to ensure human health and production safety.
