In efforts to improve water quality, 25 states have passed laws limiting the amount of phosphates in cleaning
products, such as laundry and dishwashing detergents, sold in the state. This has resulted in a patchwork of requirements that affect manufacturers, importers,
and distributors nationwide who need to watch for current and future state product bans.
A recent spurt of state legislation (both passed and pending bills) is aimed at further limiting phosphates in
dishwashing detergents as of mid-2010.
This chart outlines phosphate bans that were in place
on the state level and pending bills as of late March 2008.
