The effect of detergent phosphate levels on the cleaning process / P. D. Goulden.: En36-503/70E-PDF

"The determination of the cleaning performance of detergents containing 32%, 48% and 64% sodium tripolyphosphate (STPP) is described. The tests were carried out jointly with Ontario Research Foundation in 1970. The cleaning was measured under different conditions of‘detergent usage and water hardness. Artificially and naturally soiled fabrics were washed in a domestic washing machine. It was found that phosphate level is critical below a mole ratio STFP:CaCO3 of 0.3:1 but that above this ratio the other ingredients in a detergent formulation have as significant an effect on cleaning performance"--Abstract.
