A portion including at least one chamber having a wall made of water-soluble material, wherein the portion includes a composition which based on the total weight of the composition contains a total amount of 0.1% to 80% by weight of at least one surfactant. Wherein the composition includes at least two phases, wherein a) a first phase is a granular mixture of a solid-state composition and b) a second phase is in the form of a viscoelastic, solid-state molding of a second composition which based on the total weight of the second composition contains a total amount of more than 1% by weight of at least one benzylidene alditol compound of formula (I). Wherein *—, n, m, R1, R2 and R3, R4, R5 and R6 are defined as storage-stable, aesthetic and releases the composition contained therein rapidly and effectively to provide a surfactant-containing liquor.
