Abstract
Methods are disclosed for preparing solid alkaline detergent compositions from aqueous emulsions comprising water, a source of alkalinity, a condensed phosphate hardness sequestering agent and a solidifying agent such as anhydrous sodium carbonate, comprising heating said emulsion to hydrate and melt the solidifying agent and then cooling the mixture.
Claims25
A method for forming a solid alkaline detergent composition comprising forming an emulsion comprising water, a source of alkalinity comprising about 5-25% of an alkali metal hydroxide, a condensed phosphate hardness sequestering agent and a solidifying agent selected from the group consisting of anhydrous sodium carbonate, anhydrous sodium sulfate and mixtures thereof, said solidifying agent being being incorporated into said emulsion at about 35.degree.-50.degree. C., the amount of said agent being effective to solidify said emulsion to a homogeneous solid when it is cooled to ambient temperatures.
A method for forming a solid detergent product comprising:
- (a) forming a stirred dispersion of a synthetic hectorite clay suspending agent in water;
- (b) adding sufficient sodium or potassium hydroxide to said dispersion to raise the temperature of said dispersion to about 40.degree.-45.degree. C.;
- (c) adding sodium tripolyphosphate and a solidifying agent comprising anhydrous sodium carbonate, anhydrous sodium sulfate or mixtures thereof to said dispersion while maintaining the temperature at about 40.degree.-45.degree. C. to form a detergent emulsion;
- and
- (d) cooling said dispersion to ambient temperatures to form a homogeneous solid detergent product.
