METHOD FOR INCREASING THE INNER STABILITY OF SODIUM PERCARBONATE

摘要

The invention relates to a method for increasing the inner stability of encapsulated and non-encapsulated sodium percarbonate. According to the invention, particulate, dry sodium percarbonate is treated for at least 2 minutes at a temperature of 70 to 120 ~C and during the treatment, the air surrounding the particles is exchanged, in order to maintain or reduce humidity.
