Abstract: A soluble unit dose of laundry detergent which comprises: a) a thin walled hard capsule, having a wall thickness between 0.07 and 0.3 mm and, c) within the thin walled hard capsule a detergent composition comprising at least 1 g of surfactant, which makes up at least 45% wt of the detergent composition. wherein the solubility of the capsule and the detergent composition is such that it will reach a level of 90% of eventually dissolved electrolytes in stirred demineralised water at 25° C. in less than 35 seconds. By choice of a capsule with this wall thickness the solubility is ensured while pressure caking of the contents is resisted to minimise overall dissolution time.
