Abstract
In one aspect, the invention relates to a composition of matter comprising a plurality of powder whitening particles, substantially each of which comprises sodium carbonate and sufficient sodium precarbonate to provide from about 1 to about 6 weight percent of oxygen available. In another aspect, the invention still relates to a process for preparing a separation-resistant powder whitening composition. The method comprises contacting particulate sodium carbonate with a sufficient amount of a spray of an aqueous solution of hydrogen peroxide, the contacting being carried out at a temperature in the range of about 35ºC to about 70º c, to provide a bleaching composition. Powder having sufficient sodium precarbonate to provide from about 1 to about 6 weight percent of available oxygen, and the remainder of which comprises sodium carbonate, and recovering the dry bleaching composition just described, from the step of put in contact.
