The composition maintains its homogenous status for 1-30 months at room temperature.

US Patent No. 12,152,222 B2 (Daniel Thomas Piorkowski, Frank Meier, Peter Schmiedel); Henkel AG & Co. KGaA patented a unit dose detergent enclosed in water-soluble or water-dispersible film.

The detergent composition contains:

•  a surfactant system comprising at least one anionic surfactant comprising an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with 1-10 moles of ethylene oxide or linear alkylbenzene sulfonate and at least one non-ionic surfactant comprising an alkoxylated alcohol; water; a fatty acid or a salt thereof capable of being neutralized in the composition to release the fatty acid; a magnesium salt comprising a magnesium cation component and a counterion component; and colloidal particles.

The weight ratio between the fatty acid and the magnesium salt is from 2:1 to 30:1.

The colloidal particles are homogenously dispersed in the detergent composition. The composition maintains its homogenous status for between 1 and 30 months at room temperature.

The detergent forms a gel within 1 to 3 days of mixing all composition ingredients.
