| phosphates |
A group of compounds containing phosphorous and oxygen, which are used to enhance the effectiveness of detergents. Also a component of fertilizers, phosphates are essential plant nutrients. Phosphates residues from detergents cause excessive growth of algae and freshwater lakes and streams. As a result, many states and regions have banned phosphates from laundry detergents. They are still commonly used in dishwasher detergents because they are more difficult to replace in that application.
