Abstract
In one embodiment, the invention provides novel low-temperature-effective non-phosphate detergent paste compositions comprising: PA0 A concentrated non-phosphate, detergent paste composition which is rapidly soluble in cold water comprising, by weight: PA0 (a) about 10-50% of at least one nonionic surfactant; PA0 (b) about 5-70% of at least one water insoluble non-phosphate builder; PA0 (c) about 0-70% of at lest one water soluble non-phosphate builder; PA0 wherein the ratio of (b+c): a is greater than or equal to about 1.0; and PA0 wherein the ratio of b:a is less than about 2.0. The novel detergent paste compositions provide good removal of oily and particulate soils from both natural and synthetic fibers and yet surprisingly are rapidly soluble/dispersible in cold water. Furthermore, adjuncts such as nonionic, anionic, cationic, and amphoteric surfactants; phase stabilizers; fluorescent whitening agents; anti-redeposition agents; corrosion-inhibiting agents; dyes; pigments; bleaches, fabric softeners; enzymes; and fragrances may be added to the novel paste detergents of this invention. The invention also provides novel delivery means in the form of unit dosage size water soluble…
