Using STPP instead of EDTA in Shampoo and dishwash at pH 5

Can we use STPP in Shampoo and dishwashing liquid instead of EDTA at pH 5? 

If yes what percentage of STPP is equal to 01% Tetrasodium EDTA?

    Too harsh for shampoo and personal care. Also not very efficient metal chelation (K-value) at acidic pH.
