Abstract
A process for preparing alkaline, silicate-containing paste-form detergent compositions, having good dispensing properties, is disclosed. In the disclosed process, the solid and liquid components of the detergent composition are subjected to high-shear mixing, followed by a simultaneous mixing and cooling step in which the temperature of the mixture is reduced to less than about 100.degree. F when the temperature of the mixture exceeds about 120.degree. F during the high-shear mixing operation. In a preferred single-step embodiment, the solid and liquid components are subjected to high-shear mixing while simultaneously being cooled such that the temperature of the mixture during mixing does not exceed about 120.degree. F.
