Built detergent composition

摘要

Detergent compositions containing orthophosphate and pyrophosphate builders in prescribed ratios and magnesium silicate are claimed wherein the final composition has a minimum amount of free alkalinity as NaOH. The compositions demonstrate superior whiteness maintenance and lower undesirable residual deposits on fabrics washed therein. The compositions optionally contain a small amount of a water soluble magnesium salt, e.g., magnesium sulfate and may also contain phosphate more condensed than pyrophosphate.
