Sodium tripolyphosphate was an excellent builder used in laundry detergent powders. However, due to issues of biodegradability many countries have banned the use of phosphates in detergents. Manufacturers are using substitutes such as EDTA and other biodegradable chemicals instead. Phosphates bind calcium and magnesium ions to prevent 'hard-water' type limescale deposits. … WebPhosphates 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. The disadvantage of using phosphates is that they remain in …
