Abstract
A dosage element to be consumed in use in a ware washing machine, the dosage element including a container, whereby the container encloses a non-consolidated particulate composition and a gel in direct contact with one another.
Claims14
A method of manufacturing a ware washing unit dosage element having one compartment comprising the steps of:
- (a) introducing a gel precursor composition into a water-soluble receptacle, wherein the gel precursor composition consists of 10-60 wt % of a non-ionic surfactant, and 10-60 wt % of a polyethylene glycol having a molecular weight in the range of 150-600 with the balance being a bleach activator, and optionally 0.1-8.0 wt % of polyethylene glycol having a molecular weight in the range of 1,000-35,000, water, a dye, and/or a builder;
- (b) converting the gel precursor composition, or allowing the gel precursor composition to convert, into a shape-stable gel;
- and
- (c) introducing a flowable particulate composition into the receptacle adjacent and in direct contact with the shape-stable gel such that the shape-stable gel and the flowable particulate composition do not substantially seep into each other;
- wherein the method does not comprise consolidating the flowable particulate composition.
