Packaging and Storage:

Keep in a Cool Place: Store Copovidone in a cool environment, ideally at room temperature. Avoid exposing the product to direct sunlight or extreme heat, which can degrade the product over time.

Dry Conditions: Ensure that the storage area is dry. High humidity can affect the quality of the product. It’s best to keep Copovidone away from sources of moisture.

Avoid Direct Contact with Water: Since Copovidone can absorb moisture from the environment, it’s important to keep the containers closed and away from any sources of water.

Separation from Other Chemicals: Store Copovidone separately from other chemicals or substances that could react with it. This prevents any potential chemical reactions that could affect the product’s quality.
