A solid detergent composition suitable for use in an industrial warewashing process and in the form of a block of compressed granular material is provided, said block having a weight of 0.2-10 kg and comprising: 25-35% by weight of an alkalimetal metasilicate selected from sodium- and potassium metasilicate; 40-55% by weight of a phosphate builder; 2-4% by weight of a compressing aid selected from low foaming nonionic surfactants, metal soaps, paraffins, talcum powder, polyethylene glycol, sodium benzoate, mixtures of long chain ketones having more than 25 carbon atoms and fatty alcohols, and mixtures thereof; and up to 7.0% by weight of free water. Said block has optimal quality characteristics.
A process for making a non-phosphate, zeolite-built detergent tablet, the process comprising a first step of providing a detergent composition, a second step of forming a particulate material comprising the detergent composition, and a third step of compressing the particulate material in a tablet form, the process being characterized in that it further comprises a step of cooling the detergent composition below ambient temperature between the first and the third step.
The invention includes compositions containing one or more .alpha.-sulfofatty acid esters, and methods for making and using the same. At least one .alpha.-sulfofatty acid ester is included in an inner portion. The invented composition can further include an outer portion which protects the .alpha.-sulfofatty acid ester from di-salt formation. The resulting composition improves the stability of the .alpha.-sulfofatty acid ester after manufacture, during shipping and storage, and in detergents. The invention further included detergents containing the invented composition, and methods of making such detergents.
