Phosphorus Limited Further in Dish Soap

Governor Doyle signed into law 2009 Wisconsin Act 63 on November 12, which further limits the amount of phosphorus contained in dishwashing products. The former allowable limit for dish soap was 8.7% of phosphorus by weight, and Act 63 reduces that amount to 0.5% of phosphorus by weight. Eliminating unnecessary phosphorus waste is critical in controlling algae blooms, which have threatened lakes throughout the state.
