Phosphates in detergent refers to the use of phosphates as an ingredient in a detergent product. The advantage of using phosphates in a consumer laundry detergent or dishwashing detergent is that they make detergents more efficient by chelating calcium and magnesium ions.[1] The disadvantage of using phosphates is that they remain in wastewater and eventually make their way to a natural body of water.[1] While phosphates are low toxicity, they instead cause nutrient pollution and feed the algae. This leads to eutrophication and harmful algal bloom.[1]
Many countries have banned the use of phosphates in detergent, including the European Union and the United States.[2][3]
