    Abstract: Detersive systems that can be used to remove soil from fabrics, dishware, flatware, hard surfaces, clean-in-place installations, and other common household, institutional or industrial locations can contain a detergent capable of removing soil and a softening agent dispersed in the detergent comprising droplets having an exterior organic phase containing a complexing agent and an inner aqueous phase comprising an acid. The softening agent can adequately remove hardness ions from the detersive system made from the compositions of the invention.

    Abstract: High efficiency encapsulation of core particles, particularly halogen bleaches, by (i) encapsulating the core particle in at least two separate coats wherein the melting point of the inner or first coating material is below the melting point of the outer or second coating material, (ii) heating the thus encapsulated particle to a temperature between the melting points of the inner and outer coating materials in order to liquefy the inner coat, and (iii) allowing the liquid inner coat to solidify and form a continuous, nonporous encapsulating coating.

    Abstract: A composition capable of releasing active enzyme into an aqueous, active chlorine containing media which in a first aspect comprises an enzyme core encapsulated with an initial coating of a time-release substance, a first coating of a bleach-neutralizing substance and a second coating of a time-release substance. In a second aspect, the composition comprises an enzyme encapsulated in a time-release substance designed to delay release of the enzyme in dissolution for a first-time delay, and a bleach-neutralizing substance, present as either a core material and/or a first coating on a diluent core, which is encapsulated in a time-release substance designed to delay release of the bleach-neutralizing substance into solution for a second-time delay; the first-time delay being longer than the second-time delay so that the bleach-neutralizing substance will be released and completely neutralize all active chlorine present in the solution before the enzyme is released. In a third aspect, the composition comprises an enzyme core encapsulated with a time-release substance, a diluent core encapsulated with a first coating of a bleachneutralizing substance and a second coating of a time-release substance, and a bleach-neutralizing substance core encapsulated with a time-release substance. The invention further includes a cleaning composition which is particularly effective in warewashing which comprises one of the encapsulated enzyme-containing compositions described above, chlorine bleach, and at least one additional detergent component.
