Polyethylene glycol PEG-200 is hygroscopic, so it is crucial to keep the container tightly sealed during storage to prevent the product from absorbing moisture from the air, which could lead to quality degradation. It is recommended to store the product in a cool, dry, and well-ventilated warehouse, with the recommended storage temperature range being 15°C to 30°C. Too low temperatures may cause the product to become more viscous or even solidify, while too high temperatures may accelerate oxidation and discoloration.
Regarding the choice of storage containers, containers made of corrosion-resistant materials should be used, such as stainless steel, polyethylene, or carbon steel with an epoxy resin lining. These materials are chemically stable and will not react with PEG-200, effectively ensuring the purity and quality of the product. The storage area should also be equipped with spill containment facilities to handle accidental leaks.
PEG-200 should be stored away from strong acids, strong oxidizers, and other incompatible substances to avoid unnecessary chemical reactions. It should also be kept away from fire sources and avoid prolonged exposure to air. Although this product is not flammable or explosive, good storage management helps extend the product's shelf life and ensure stable and reliable performance during use.

For users who purchase in bulk and store long-term, it is recommended to follow the "first in, first out" principle and regularly check container seals. If an increase in moisture content is found due to moisture absorption, vacuum dehydration treatment can restore performance. When dispensing small quantities, minimize the number of times the container is opened and the exposure time, and seal it immediately after taking material to prevent moisture and impurities from entering the container. In winter, if the product becomes more viscous, move the container to a warm environment to naturally warm up before use, and never heat it directly with an open flame.
