Abstract
The invention relates to a process for stabilizing particulate alkali metal percarbonate by coating by coating it with an aqueous solution, preferably concentrated, of a complex formed from a boric acid or borate and an organic diol, polyol or hydroxycarboxylic acid, to the resulting coated product, and to compositions including the product. The coating can additionally contain an alkali metal neutral salt such as sodium chloride or sodium sulphate.
