<p>A cleaning composition comprises an alkali metal carbonate detergency builder with a seed crystal material therefor and a heavy metal sequestrant. To avoid deleterious interactions with the seed crystal material, the sequestrant is immobilised on a high surface area solid support medium. The composition may be in the form of powders, aqueous liquids, substantially non-aqueous liquids, gels or pastes.</p> |
