Definitions

  • the invention relates to a method of dispensing functional material from a dispenser by directing water onto an article contained in said dispenser in order to form a concentrate and directing said concentrate to a use location.
  • the invention further relates to a method for delivering an aqueous alkaline wash chemical and to a method of dispensing multiple volumes of an aqueous solution of a wash chemical from a dispenser.
  • Powders also have a tendency to clump and cake after they have been contacted with water and allowed to dry in a dispenser over a period of time. This caking of the powdered detergent diminishes the amount of exposed surface area which can be contacted by water in the dispenser during subsequent detergent formation cycles. The caking of the powdered detergent thus interferes with dispensing efficiency.
  • Solid cast detergents have solved the basic problems in the use of powdered detergents. However, many customers continue to use powdered detergents out of habit or from a reluctance to install new dispensers or for cost or other reasons.
  • an article 16 comprising a sealed water soluble bag 3 containing a pelletized functional composition 4 situated in a dispenser 5. (See Fig. 1.)
  • the water impervious outerwrap 2 can comprise a variety of forms including but not limited to the following: a box, a carton, an envelope, a bag, a tub, a pail, a can and a jar.
  • the water impervious outerwrap comprises a flexible bag for reasons of ease of handling and storage.
  • the temperature of the water sprayed through the nozzle 11 onto the article 16 can vary depending upon the composition of the water soluble container 3 and the pelletized functional material 4.
  • the article 16 could be used in various other dispensers including but not limited to the following: water in reservoir dispensers and hydraulic dispensers.
  • the dispenser 5 previously described is preferred in that the user by means of the ionic sensor device or other concentration monitoring device can accurately control the concentration of functional material contained in the solution.
  • the article 16 can contain a multiple use amount of a pelletized functional material 4 including but not limited to a fabric treatment composition, a warewashing composition, a laundry composition, a pot and pan cleaner or presoak composition, a silverware cleaner or presoak composition, a floor cleaner composition, a rinse additive composition, a disinfectant composition, a general purpose cleaner composition, etc.
  • the pelletized materials are room temperature solids. The materials are solidified by a variety of mechanisms, including compressive molding, compressive pelletizing, casting, hydration hardening, the user of organic hardening agents, etc.
  • the laundry detergent pellet may also comprise 0-30 wt-% water of hydration, preferably 0 to 15 wt-% for reasons of ensuring a strong pellet that resists breakage and dusting and concentrating the product actives.
  • Suitable quaternaries include but are not limited to the following: quaternary ammonium chlorides, quaternary ammonium methyl sulfate, imidazolinium-type quaternaries, dialkyl dimethyl quaternaries, monoalkyl trimethyl quaternaries, and diamide amine based quaternaries.
  • the quaternaries utilized are solid and have a melting point above about 48.8°C (120°F). Quaternaries used in the present invention should have fabric softening capabilities and static reduction capabilities.
  • the quaternary comprises distearyl dimethyl ammonium chloride for reasons of efficacy and melting point.
  • the defoaming surfactant comprises an alkyl sulfate ester for economic reasons.
  • the test was run as follows: For six months, three different powdered detergents were utilized in dispensers for institutional warewashing machines in a number of test machines. The performance of the powders were evaluated to determine whether staining, filming and spotting of cups, glassware and silverware occurred.
  • a “defoamer” is a chemical compound with a hydrophobe/hydrophile balance suitable to reducing the stability of protein foam.
  • the hydrophobicity can be provided by an oleophilic portion of the molecule (e.g. and aromatic alkyl or aralkyl group; and oxypropylene unit or oxypropylene chain, or other oxyalkylene functional groups other than oxyethylene, e.g. tetramethylene oxide).
  • the hydrophilicity can be provided with oxyethylene units or chains or blocks and/or ester groups (e.g. organophosphate esters), salt-type groups, or salt-forming groups.
  • the pelletized presoak composition may also comprise 0.01 to 5.0 wt-% of an enzyme, preferably 0.5 to 2.0 wt-% for reasons of soil removal and most preferably 1.0 wt-% of an enzyme for reasons of soil removal.
  • Suitable enzymes include but are not limited to the following: esperase, amylase, lipase, and combinations thereof. Esperase serves to break down protein, whereas amylase breaks down starch and lipase breaks down fats. If three enzymes are utilized in the presoak composition, the broad range for each enzyme would range from between 0.1 to 5.0 wt-%. Thus, the presoak can comprise up to 15 wt-% enzyme if three different enzymes are utilized.
  • the pellets had the following composition: Ingredients Wt-% 1. Sodium sulfate 82.4 2. Linear dodecyl benzene sulfonate 14.7 3. Low alkaline sodium silicate 1.0 4. Dye .0075 5. Diatomaceous Earth - (flow agent) 1.0 6. Emollient .3925 7. Sodium polyacrylate .5
  • a preferred buffering agent comprises sodium bicarbonate.
