Abstract (en)
A detergent composition, particularly for fabric washing or dishwashing, contains a detergent active compound, an orthophosphate builder and an alkalimetal bicarbonate to reduce the initial pH. The bicarbonate is in particulate form with a preferred particle size of 50 to 500 microns. A typical composition contains 5 to 30% detergent active, 10 to 30% of a mixture of tripolyphosphate and orthophosphate in a ratio of 10:1 to 1:5 and 2 to 15% bicarbonate. Preferably the compositions also include an alkalimetal silicate in similar amounts to the bicarbonate. In use the composition gives an initial pH below 11.0 and a final pH between 9.0 and 11.0.
