Anti-redeposition effects from enzymes

Detergent enzymes can provide a range of benefits under practical washing c onditions. One area of benefit is improved anti-redeposition performance. T he anti-redeposition effects of amylases are related to the soil binding th at is caused by traces of starchy material. Starch is a widespread trace co ntaminant on cellulosic fibres and complete removal of all starch under hou sehold washing conditions requires the use of amylase. Certain cellulases provide significant anti-redeposition effects. Methods f or studying this under realistic washing conditions are described Anti-rede position performance results under European conditions indicate that cellul ases can contribute both to powder and, in particular, to liquid detergent formulations.
