Patent number: 6479455Abstract: A process for improving storage stability and solubility of a laundry detergent powder includes the steps of: (a) forming a builder agglomerate which is free of sodium carbonate and (b) adding the builder agglomerate to a laundry detergent powder composition. The builder agglomerate is present in an amount in a range of from about 14% to about 21% by weight of the laundry detergent powder composition. The builder agglomerate has a composition including an aluminosilicate ion exchange and a binder selected from the group consisting of surfactants, polyethylene glycol, polyacrylates, and mixtures thereof. The builder agglomerate also includes sodium diethylenetriaminepentaacetate (DTPA) and balance water but the builder agglomerate is free of sodium carbonate.Type: GrantFiled: March 19, 2001Date of Patent: November 12, 2002Assignee: The Procter & Gamble CompanyInventors: Joseph Michael Cruse, Michael Chris Jensen
