Abstract
The present invention relates to a pouched cleaning composition wherein the pouch is constructed from a water-soluble film and contains a liquid composition comprising less than 5% by weight of the liquid composition, of water; an anionic surfactant; and at least 0.5% by weight of the liquid composition of a builder/chelant free of C8-22 alkyl or alkenyl chains characterized by a solubility in said liquid composition of less than 0.3% by weight. Such pouched cleaning compositions provide better cleaning performance and better pouch solubility while avoiding the formation of residues.
