Abstract
Provided herein are detergent compositions in solid sheet form that include a detergent component and activated charcoal dispersed in the detergent sheet. The activated charcoal is lightweight, porous and has high surface area to weight ratio. The detergent component and activated charcoal work synergistically to enhance cleaning and stain removal efficacy. The detergent compositions may be a laundry detergent sheet or a toilet bowl cleaner sheet.
Claims20
A laundry detergent sheet comprising:
- a water-soluble matrix in sheet form, the water-soluble matrix comprising a solidified polymer mixture;
- a detergent component bound and suspended by the water-soluble matrix, the detergent component comprising ionic and non-ionic surfactants, and 0.2%-5% enzymes wherein the enzymes are selected to break down certain molecules on soiled laundry;
- activated charcoal, the activated charcoal comprising particulate carbon having a porous exterior surface and an average surface area of at least 950 m2/g, wherein the activated charcoal is embedded in the water-soluble matrix;
- and
- wherein the water-soluble matrix is configured to release the detergent component and the activated charcoal when the water-soluble matrix contacts a sufficient volume of water such that the porous exterior surface of the activated charcoal adsorbs at least some of the molecules broken down by the enzymes.
