Polyethylene glycol PEG-600 is a colorless to slightly yellow viscous liquid at room temperature, and becomes a waxy solid in low-temperature environments. Due to the presence of numerous ether oxygen groups in its molecular structure, it has strong hygroscopicity. Therefore, keeping the container tightly sealed during storage is a key measure to prevent product moisture absorption and deterioration. Moisture absorption not only affects the purity and performance but may also cause viscosity changes and microbial growth.
Regarding temperature control, it is recommended to store at temperatures not exceeding 40°C, while avoiding solidification or overheating. PEG-600 has a relatively low freezing point and may solidify during cold seasons, but this usually does not affect product quality and it can be used normally after returning to room temperature. However, frequent freeze-thaw cycles may adversely affect product uniformity, so maintaining a relatively constant storage temperature is recommended.
Although this product is not classified as a hazardous substance, it is combustible. During storage, keep away from fire, heat sources, and direct sunlight, and store separately from strong oxidizing agents (such as peroxides, hypochlorites, permanganates, etc.), strong acids, and strong bases, maintaining a safe distance. Also keep away from food, beverages, and animal feed, and regularly check packaging integrity to prevent leaks.

For users in various application fields, it is recommended to store in portions based on usage frequency and quantity:
If a spill occurs, immediately cover and collect the material with an inert absorbent (such as sand, vermiculite, universal absorbent) and place it in a sealed, labeled container. Do not allow the spillage to enter drains, waterways, or soil. Empty containers must not be used for other materials until thoroughly cleaned, and should not be disposed of arbitrarily. They should be disposed of in compliance with local regulations by a qualified waste treatment facility.
