Abstract (en)
[origin: GB2315764A] A detergent composition is selected from: (i) a particulate base composition having a core which comprises a solid surfactant and an alkaline source, and an outer layer comprising an acid source; (ii) a particulate base composition comprising an alkaline source and having a core comprising an acid source, and an outer layer comprising a surfactant. A process for the manufacture of a detergent composition is selected from: (i) admixture of a solid surfactant with an alkaline source, and coating at least said surfactant with an acid source; (ii) making a base composition comprising a solid acid source, coating said source with a surfactant, and further adding an alkaline source. A gas is produced on reaction of the acid source and alkaline source. The alkaline source is preferably selected from an alkali metal carbonate, alkali metal bicarbonate, alkali metal sesquicarbonate, alkali metal percarbonate, alkaline earth metal carbonate, alkaline earth metal bicarbonate or alkaline earth metal sesquicarbonate. The acid source may be selected from organic acids (preferably citric acid, glutaric acid, succinic acid or adipic acid) and inorganic (including mineral) acids (preferably monosodium phosphate, sodium hydrogen sulphate or boric acid).
