The total level of phosphorus in the cleaning product will
be limited to a maximum level of 0.5 weight % in the cleaning product as sold
(measured as elemental phosphorus).Inorganic phosphates as defined by the US EPA New Chemicals Program [104] cannot make up any portion of the 0.5 weight % of phosphorus.
Note: Inorganic phosphates as defined by the US EPA New
Chemicals Program [104] will not be allowed in
DfE-labeled products due to their potential to contribute to eutrophication of
fresh water and estuarial ecosystems.Eutrophication is a priority concern for EPA scientists, and inorganic
phosphates create a greater concern for eutrophication than alternative
Chelating and Sequestering Agents used for this purpose.Given that the majority of DfE-labeled
products are disposed of down the drain, they end up in wastewater
streams.EPA acknowledges
contributions to the phosphorus load from cleaners are relatively small in
comparison with other sources and that eutrophication is not an issue in all
locations.The EPA policy is
consistent with a commitment to reduce contributions of inorganic phosphorus
from DfE-labeled products regardless of concentration.
