The core cleaning composition itself includes an ionic liquid, water present in an amount of from 10 to 50 parts by weight per 100 parts by weight of the core cleaning composition, and at least one of a chelant, an enzyme, and a surfactant. The water-soluble film has a disintegration time of less than 90 seconds as determined at 40° C. using distilled water according to MSTM 205, when disposed about the core cleaning composition. The water-soluble film also remains stable for 6 months at 25° C., when disposed about the core cleaning composition. ## Claims ### Claim 1 An encapsulated cleaning composition comprising: A. a core cleaning composition comprising: an ionic liquid, water present in an amount of from 10 to 50 parts by weight per 100 parts by weight of said core cleaning composition, and at least one of a chelant, an enzyme, and a surfactant;
