Dry bleaches or all‐fabric dry bleaches are increasing in usage (7% +, annually, is quoted) because the consumer is seeking fabric and dye safety coupled with good stain removal. Additionally, the consumer wants a product which requires less sorting of fabrics or colors and aids in the cleansing and stain‐removal action without color, fabric, or finish damage. The leading bleach ingredients for dry all‐fabric bleaches are peroxygen salts. One of the newest of these peroxygens with a good combination of performance characteristics — for bleaching, good stain removal, positive building action, and cumulative whitening — is the advanced FB™ Sodium Percarbonate. This presentation looks at the formulation of dry bleaches, their constituents, and how market needs are met, and examines the properties of the two persalt alternatives.
