The desiccant is designed in order to absorb excess moisture, thus preventing it from making its way into the gap between the glass panes. However, once it is over saturated, the desiccant begins to lose its ability to absorb water and eventually, the moisture between glass will increase, leading to the mist that is commonly seen.
