Stain removal automatic dishwashing detergents

In recent years, researchers have explored electrochemical methods for use in automatic dishwashing for sanitization and stain removal. In dishwashers, it has been observed that electrochemical cells operate by making use of the water electrolysis process, where OH present in the water from the electrolytic dissociation of water molecules donates an electron to the anode and is therefore oxidized to oxygen gas, which can be removed from the system. As a result, is enhanced at the anode-water interface, and enriched acidic water is produced. The advantage of this electrolyzed water is that it can provide improved cleaning, stain removal, and sterilization benefits in automatic dish care. Combined with ADD compositions, electrolyzed water can be effective at removing a number of soils and stains from dishware. Additionally, the combination of electrolyzed water with ADD combinations may alleviate the need to add additional bleach to the detergent.

While enzymes have played a role in powder detergents in the U.S. market over the years, more recently they have started to emerge as additives in LADD formulations. Both proteases and amylases have appeared in LADDs in spite of the fact that, unlike powders, oxygen bleaches could not be incorporated for stain removal. They first appeared in bottled liquid/gel products in 2000 in the U.S. These were introduced as premium products, with dual enzymes, and captured about 5% of the total automatic dishwashing market.
