  • Patent number: 6595008
    Abstract: A process is provided for the safe storage of sodium percarbonate in a bulk container that is substantially closed to the ambient atmosphere. A temperature is measured at at least one position inside the sodium percarbonate stored in bulk and, with an increase in temperature within the range of 0.5 to 10° C. per day, in particular 1 to 5° C. per day, dry air is passed periodically or continuously through the bulk material until the increase in temperature has fallen to a value of less than 1° C. per day in particular less than 0.5° C. per day.
