Water soluble sachet containing hard surface cleaner

1. A water soluble container enclosing a concentrate composition consisting of:

(a) at least one surfactant which is either:

(i) a C 10 -C 14 alkyl sulfate surfactant, a C 10 -C 14 alkyl ether sulfate surfactant or mixture thereof, further in conjunction with one or more nonionic alkylpolyglycoside surfactants, or

(ii) at least one nonionic surfactant based on an ethoxy/propoxy block copolymer, further in conjunction with at least one nonionic surfactant based on an ethoxylated fatty alcohol;

(b) at least 70% wt. of at least one organic solvent having a solubility in water of at least 4% wt. selected from the group consisting of propylene glycol n-butyl ether, propylene glycol methyl ether, and mixtures thereof, and optionally a C 1 -C 6 glycol or a C 1 -C 6 monohydric alcohol;

(c) in excess of 7.5% wt. water, but no more than 12.5% wt. water;

(d) optionally, at least one alkanolamine; and

(e) optionally, up to about 10% wt. of one or more conventional additives selected from coloring agents, fragrances and fragrance solubilizers, further surfactants, pH adjusting agents and pH buffers, optical brighteners, opacifying agents, hydrotropes, anti-oxidants, and preservatives.

2. A water soluble container enclosing a concentrate composition according to claim 1 wherein the at least one alkanolamine is present in the composition.

3. A water soluble container enclosing a concentrate composition according to claim 1 wherein the concentrate composition exhibits a flash point of at least 105° F.

4. A water soluble container enclosing a concentrate composition according to claim 1 wherein the C 1 -C 6 glycol, or the C 1 -C 6 monohydric alcohol is present in the composition.

5. A water soluble container enclosing a concentrate composition according to claim 4 wherein the organic solvent consists of propylene glycol n-butyl ether, propylene glycol methyl ether and a C 1 -C 6 monohydric alcohol.

6. A water soluble container enclosing a concentrate composition according to claim 4 wherein the organic solvent consists of propylene glycol n-butyl ether, propylene glycol methyl ether and a C 1 -C 6 glycol.

7. A water soluble container enclosing a concentrate composition according to claim 1 wherein the (e) further surfactant is an alkoxylated quaternary ammonium compound.

8. The water soluble container according to claim 1 which is a thermoformed or injection molded water soluble polymer.

9. The water soluble container according to claim 8 wherein the water soluble polymer is poly(vinyl alcohol).

10. A water soluble container enclosing a concentrate composition according claim 1 wherein the (b) the at least one organic solvent having a solubility in water of at least 4% wt. is present in an amount of at least 75% wt.

11. A water soluble container enclosing a concentrate composition according to claim 1 , characterized in that when said water soluble container and concentrate composition are dissolved in a larger quantity of water to form a cleaning composition therefrom, said cleaning composition exhibits low streaking characteristics when used to clean polished hard surfaces selected from the group consisting of: polished metal surfaces, glass, and mirrors.

12. A process for treating a surface, particularly a hard surface especially one or more selected from polished metal surfaces, glass and mirrors in need of cleaning, comprising the process steps of:

placing a water soluble container containing a concentrate composition according to claim 1 into a larger quantity of water;

allowing the water soluble container to dissolve in the water to form a cleaning solution;

and applying an effective amount of the solution to the surface in need of treatment.
