Abstract
Elimination of phosphates from detergents alone, is insufficient to solve the eutrophication problem. Nevertheless, the endeavors of the detergent industry are aimed at finding phosphate subsitutes. Novel approaches for at least a partial replacement of detergent phosphates have been found by using water‐soluble organic complexing agents as well as heterogeneous organic or inorganic ion exchangers. So far, a large‐scale replacement is not possible. It is not justifiable until all technical requirements are met with and safety with regard to man, animals, plants and drinking water has been established.
