Effects of builder addition on characteristics of aqueous systems containing surfactant and other ingredients of detergent formulations

ABSTRACT The builders tested were: pentasodium triphosphate, trisodium nitrilotriacetate, trisodium citrate, and tris(triethanolammonium) citrate. The characteristics measured were: stability in hard water, foaming power, wetting power for raw cotton cloth, soil removal efficiency, and redeposition effects. The results of the preliminary exploratory phase show that these builders modify positively or negatively (with different statistical significance)the values of the measured characteristics. Therefore a clear and single behaviour pattern cannot be established without more extensive research. Modifications of the measured
