摘要： The invention is an improved, non-phosphate, non-bleach, agglomerated laundry booster which has a) a solids portion with i) at least 5% by weight of a first builder selected from the group consisting of alkali metal carbonate, alkali metal bicarbonate, alkali metal sesquicarbonate, and mixtures thereof; and ii) a second builder of at least 25% by weight alkali metal tetraborate pentahydrate; and b) i) a first liquid which comprises an anionic, acidic surfactant, in an amount no greater than about 10% by weight; and ii) a second liquid which comprises an agglomerating agent. The first liquid is neutralized by the first builder of a)i) to form a first set of particles, the second builder forms a second set of particles, and the second liquid co-agglomerates both the first and second sets of particles. The invention also provides a method for preparing this laundry booster.
