Abstract:
A non-phosphate, non-bleach agglomerated laundry booster comprising:a) a first set of particles, comprising an alkaline builder, at least a portion of which has been used to neutralize in situ an acidic, liquid surfactant, in which:(i) said alkaline builder is at least 5% by weight of the agglomerated laundry booster, said alkaline builder being selected from the group consisting of alkali metal carbonate, alkali metal bicarbonate, alkali metal sesquicarbonate, and mixtures thereof, and(ii) said acidic liquid surfactant is about 0.01-10% of the agglomerated laundry booster, said acidic liquid surfactant being selected from the group consisting of C.sub.6-20 alkylarylsulfonic acids, C.sub.6-20 alkylsulfonic acids, C.sub.6-20 alkylsulfuric acids, C.sub.6-20 alkylcarboxylic acids and mixtures thereof;b) a second set of particles comprising at least 25% by weight of the agglomerated laundry booster of an alkali metal tetraborate pentahydrate;c) a liquid agglomerating agent selected from the aqueous solutions of water soluble polymers, alkali metal silicates, and mixtures thereof;said liquid agglomerating agent of c) co-agglomerating said first and second sets of particles, the agglomerates thus formed of said first and second sets of particles having a density of about 0.60-0.80 g/cc.
