  • Patent number: 12415974
    Abstract: A unit dose multi-purpose cleaner concentrate product includes from 4 grams to 50 grams in mass of a concentrated cleaning composition encased in a water soluble film. The concentrated cleaning compositions include at least one cleaning solvent and at least one surfactant. The concentrated cleaning composition further includes a disinfecting agent, an antimicrobial agent as a preservative, or both. A total weight percentage of the at least one cleaning solvent and the at least one surfactant, expressed on an anhydrous basis, is at least 50% of the weight of the unit dose multi-purpose cleaner concentrate product. Methods of cleaning surfaces using the unit dose multi-purpose cleaner concentrate product are also disclosed.

  • Patent number: 10767140
    Abstract: A dishwasher composition includes at least one strong chelant, at least one weak chelant, a structural constituent, at least one surfactant, and a primary polymer. The primary polymer includes a copolymer having sulfonic acid monomer units and monomer units comprising one or more supplemental monomers, wherein the primary polymer comprises from 10 wt. % to 50 wt. % sulfonic acid monomer units and has a weight average molecular weight of less than or equal to 20,000 g/mol. The dishwasher composition can be a liquid or a gel and has a pH of from 7.0 to 9.5. Methods of washing articles include preparing a wash solution that includes water and the dishwasher composition, and contacting at least one article with the washing solution during at least a portion of a wash cycle of a commercially-available dishwasher.

  • Patent number: 10316277
    Abstract: A unit dose laundry composition includes from 1 wt. % to 10 wt. % of one or more coated enzymes, from 1 wt. % to 40 wt. % of a bleach composition comprising an oxidizing agent and one or more bleach activators, from 15 wt. % to 80 wt. % of a surfactant composition, and one or more of an alkaline compound, a detergent builder, a chelant, or a polymer composition. The unit dose laundry composition is in the form of a powder, which has a bulk density of from 500 g/L to 1300 g/L, encapsulated a polymer film. A method of making the unit dose laundry composition includes combining one or more liquid active components with one or more high absorbing solid active components to produce a powder intermediate which may be blended with other solid components.
