Abstract
A method for producing a solid alkaline detergent in which an effective amount of a hardness sequestering agent is mixed in an aqueous solution containing less than about 51 percent of an alkali metal hydroxide or an alkali metal silicate at a temperature between about 55.degree. F. and about 130.degree. F. to form a liquid dispersion. A solid caustic material is then added to the liquid dispersion in sufficient quantity to cause the eventual solidification of the dispersion. The dispensed is then mixed until homogeneous and can then be dispersion into a suitable receptacle and permitted to solidfy.
