Abstract
A solid-shaped detergent comprising particles for detergent, wherein the particles have a dissolution rate of 90% or more, under conditions where the particles are supplied in water at 5° C.; stirred for 60 seconds under the stirring conditions that 1 g of the particles are supplied to a 1-L beaker having an inner diameter of 105 mm which is charged with 1 L of hard water having 71.2 mg CaCO/L, wherein a molar ratio of Ca/Mg is 7/3, and stirred with a stirring bar of 35 mm in length and 8 mm in diameter at a rotational speed of 800 rpm; and filtered with a standard sieve having a sieve-opening of 74 μm as defined by JIS Z 8801, wherein the dissolution rate of the particles is calculated by the Equation (1):Dissolution Rate (%)=[1−()]×100,  (1)wherein S is a weight (g) of the particles supplied; and T is a dry weight (g) of insoluble remnants of the particles remaining on the sieve when an aqueous solution prepared under the above stirring conditions is filtered with the sieve.
