Reduce moisture of crospovidone

How to reduce the moisture of crospovidone?

As we know, the crospovidone is very easy to absorb water, so we suggest our customers to keep it in cool, dry and ventilated place. But when you opened the original packing and can not use all of them one time, it will be very hard to keep the same moisture condition for the left crospovidone. So if the crospovidone absorb more water than needed, how to reduce the moisture of crospovidone?

Here is our suggestion:

(1). Use boiling dryer, setting 50-60, 30% humidity, 3-4 hours, it will be easy to reduce the moisture less than 5%.

(2)If you do not have boiling dryer, only hot air circulation oven, we suggest to increase the temperature to 80, 1 hour later, you should get the crospovidone with the right moisture.
