 <p style="text-align:center"The time should not be too long, as this will increase the formation of inmeltable 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℃.
The short-term crystallization of Desmodu CD will not have a major adverse impact on its quality, but will only affect its shelf life. Therefore, the CD after re-melting will not have a major adverse impact on its quality. The product should be used as soon as possible.
