<p style="text-align:center"The time should not be too long, as this will increase the formation of infusible dimers. It should be ensured that all the product in the container is heated and melted evenly. After melting, it should be cooled immediately and the container should be sealed and stored in an environment of 20~25°C.
The short-term crystallization of Desmodos CD will not have a big adverse effect on its quality, but will only affect its shelf life. Therefore, the original product after remelting Products should be used as soon as possible.
