A process for making detergent builder agglomerates by mixing crystalline aluminosilicate or layered silicate detergent builder with selected binder in an energy-intensive mixer to form free flowing agglomerates. The binder is an anionic synthetic surfactant paste or a water-soluble polymer containing at least about 50% by weight of ethylene oxide, and optionally may contain minor amounts of ethoxylated nonionic surfactant. The agglomerates are also substantially free of amorphous alkali metal silicates if free water is present.

Process for agglomerating aluminosilicate or layered silicate detergent

Flakes of a hydrophilic solid organic material, e.g., polyethylene glycol are formed from a melt of said solid organic material on a belt cooler. The process is improved by wetting the belt cooler with water and/or an organic, low molecular weight, hydrophilic liquid to maintain contact between flake and belt during rapid cooling.

Process for forming flakes

This invention relates to a process for neutralizing detergent acid mixes containing unreacted sulfating agent such as sulfuric acid with an alkaline component such as sodium hydroxide. The neutralization process is highly exothermic and contains as a by-product large amounts of sodium sulfate. Due to the exothermic nature of the reaction it is necessary to use heat exchangers to regulate the temperature of the reaction mass following the addition of the alkaline component. When the sodium sulfate is supersaturated in the reaction mass, it has been observed that sulfate salts buildup upon the surfaces of the heat exchanger and eventually the system must be shut down to remove the buildup. This invention is therefore directed to a continuous neutralization and heat exchange process wherein the downtime required for removal of the sulfate salts from the heat exchanger surfaces is effectively eliminated.

Energy transfer

Laundry detergent compositions comprising an organic surface-active agent and low concentrations of substantially water-insoluble starch, the starch being added to the compositions as an intimate comixture with polyethylene glycol having a molecular weight of from about 400 to about 50,000, are disclosed. These compositions impart anti-wrinkling and ease-of-ironing benefits to fabrics laundered with them.

Neutralization process

Low viscosity detergent acid mixes are prepared by reacting an ethoxylated alcohol, alkyl benzene, fatty alcohol, or other sulfatable detergent precursor with a sulfating agent in the presence of benzoic acid. Benzoic acid does not sulfonate under the conditions of the improved process.

Acid mix process

Low viscosity detergent acid mixes are prepared by reacting an ethoxylated alcohol, alkyl benzene, fatty alcohol or other sulfatable detergent precursor with a sulfating agent in the presence of benzoic acid. Benzoic acid does not form a sulfonate in the composition.

Acid mix compositions containing benzoic acid

A non-phosphate built granular detergent composition is prepared which exhibits a free-flowing character resulting from the addition to the composition of benzoate salts as an anti-caking aid.
