Water soluble sachet containing hard surface cleaner
View Patent ↗The invention relates to a water soluble container which containing concentrate composition useful for hard surface disinfecting and cleaning comprising: (a) at least one cationic surfactant having germicidal properties; (b) at least one non-ionic surfactant; (c) at least one organic solvent having a solubility in water of at least 4% wt.; (d) optionally, at least one alkanolamine; (e) optionally, at least one polyethylene glycol; and (f) optionally, up to about 10% wt. of one or more conventional additives selected from coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents, other surfactants, other antimicrobial/germicidal agents, pH adjusting agents and pH buffers including organic and inorganic salts, optical brighteners, opacifying agents, hydrotropes, antifoaming agents, enzymes, anti-spotting agents, anti-oxidants, preservatives, and anti-corrosion agents; wherein said concentrate composition contains no more than 20% wt. water, and desirably contains less. The water soluble containers can be made by thermoforming or injection molding. Methods for the manufacture of such containers containing the concentrate compositions and methods for the treatment of hard surfaces using the concentrate compositions and especially aqueous dilutions of the concentrate compositions are disclosed.
1. A water soluble container containing a composition comprising:
(a) 0.01 to 20% wt. of at least one cationic surfactant having germicidal properties;
(b) at least one non-ionic surfactant;
(c) at least one organic solvent having a solubility in water of at least 4% wt.;
(d) at least one alkanolamine;
(e) at least one polyethylene glycol which is different than component (c); and
(f) optionally, up to about 10% wt. of one or more conventional additives selected from coloring agents, fragrances and fragrance solubilizers, viscosity modifying agents, other surfactants, other antimicrobial/germicidal agents, pH adjusting agents and pH buffers including organic and inorganic salts, optical brighteners, opacifying agents, hydrotropes, antifoaming agents, enzymes, anti-spotting agents, anti-oxidants, preservatives, and anti-corrosion agents;
wherein said composition contains no more than 20% wt. water.
2. The container according to claim 1 which comprises a thermoformed or injection molded water soluble polymer.
3. The container according to claim 2 wherein the water soluble polymer is poly(vinyl alcohol).
4. The container according to claim 1 wherein (b) at least one non-ionic surfactant is present in an amount of from about 0.01 to about 40 percent by weight.
5. The container according to claim 1 wherein (c) at least one organic solvent is present in an amount of from about 5 to about 97 percent by weight.
6. The container according to claim 1 wherein the (d) at least one alkanolamine is present in an amount of from about 0.01 to about 15 percent by weight.
7. The container according to claim 1 wherein the (e) at least one polyethylene glycol is present in an amount of from about 2 to about 75 percent by weight.
8. The container according to claim 1 wherein the concentrate composition contains no more than 15% wt. water.
9. The container according to claim 1 wherein the concentrate composition contains no more than 3% wt. water.
10. The container according to claim 1 wherein the concentrate composition contains no more than 1% wt. water.
11. A method of preparing a dilute treatment composition comprising placing a water soluble container according to claim 1 into an amount of water within a further container, and allowing the said water soluble container to at least partially dissolve and thereby release its contents to the water within said further container.
12. A process for treating a hard surface wherein the presence of undesired microorganisms are suspected, comprising the process steps of:
placing a water soluble container according to claim 1 into a quantity of water within a further continer
allowing the water soluble container to dissolve in the water present in said further container to form a dilute treatment composition;
and, applying an effective amount of the diluted treatment composition to the surface in need of treatment in order to provide sanitizing or disinfecting effect thereto.
