Wait I add TSP to laundry and dishes. I thought it was a rinsing agent. Plus I thought TSP was in all cleaning products until it was banned recently over pollution.
Tri-sodium phosphate can act as a rinsing agent, but not the best.
There's a ban/restriction on the percent elemental phosphorous as "p" or phosphate P2O5 in certain areas in the country and by product category. Some phosphonates are exempted, even though they contain elemental P.
ETA: and the pollution aspect is not that phosphates are toxic. They are actually fertilizers that encourage plant growth. The environmental concern is the eutrophication of water ways caused by the excessive plant growth due to phosphates in surface waters. Have you ever seen a lake with tons of algae, Lillie's, cat tails and other aquatic plants? They can 'kill' a lake pretty quick by making it inhospitable to fish and other aquatic animals necessary for a healthy ecosystem.
And 90% of the phosphates found in surface waters were from agricultural use, not household or institutional use in cleaning products. Big Ag gets off pretty easy, while the consumer gets stuck with more expensive, less effective products. Thanks EPA!
