- the present invention relates to automatic dishwashing detergents and rinse aids. More particularly, the invention relates to automatic dishwashing detergents and rinse aids, as well as to dosage forms which provide detergents and clear rinses in a product containing certain polymers. These agents are hereinafter summarized under the generic term "detergent for machine dishwashing” or "automatic dishwashing detergent”.
- Machine-washed dishes are often subject to more stringent requirements today than manually-washed dishes. So even a completely cleaned of leftovers dishes is then rated as not flawless if it has after dishwasher washing whitish, based on water hardness or other mineral salts stains that come from lack of wetting agent from dried water droplets.
- the automatic cleaning of dishes in household dishwashers usually includes a pre-wash, a main wash, and a rinse cycle interrupted by intermediate rinses.
