Abstract

A powdered cleaning composition includes at least one acid chosen from citric acid, glycolic acid, and combinations thereof and present in an amount of from about 1 to about 30 wt % actives based on a total weight of the composition, at least one anionic surfactant present in an amount of from about 5 to about 50 wt % actives based on a total weight of the composition, and at least two fillers chosen from a salt, a sugar, and a clay and present in a total amount of from about 10 to about 80 wt % actives based on a total weight of the composition, wherein the composition comprises water in an amount of less than about 15 wt % based on a total weight of the composition, and wherein the composition has a dissolution percentage of at least about 12% after about 5 minutes in water at about 25° C.

Claims (28)

1. A tablet comprising:

citric acid present in an amount of about 14.8 wt % actives, based on the total weight of the tablet;

an anionic surfactant that is either (1) sodium dodecylbenzene sulfonate present in an amount of about 28 wt % actives, based on the total weight of the tablet, or (2) sodium cocoyl isethionate present in an amount of about 12 wt % actives, based on the total weight of the tablet;

bentonite clay present in an amount of about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt % actives, based on the total weight of the tablet;

sodium chloride present in an amount of about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt % actives, based on the total weight of the tablet;

sucrose present in an amount of about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt % actives, based on the total weight of the tablet; and

water in an amount of less than about 15 wt %, based on a total weight of the tablet,

wherein:

the bentonite clay, sodium chloride, and sucrose are present in a weight ratio of actives of about 1:1:1, about 4:1:1, about 1:4:1, or about 1:1:4,

the tablet has a hardness of at least about 20 N, and

the tablet has a dissolution percentage of at least about 12% after about 5 minutes in water at a temperature of about 25° C.

2. The tablet of claim 1 , wherein the tablet is formed as a briquette, a pill, a pellet, or a brick.

3. The tablet of claim 1 , wherein the tablet is formed by pressing powder into the tablet using a force.

4. A tablet having improved dissolution in water, the tablet comprising:

citric acid present in an amount of about 14.8 wt % actives, based on the total weight of the tablet;

an anionic surfactant that is (1) sodium dodecylbenzene sulfonate present in an amount of about 28 wt % actives, based on the total weight of the tablet, or (2) sodium cocoyl isethionate present in an amount of about 12 wt % actives, based on the total weight of the tablet;

a filler comprising bentonite clay, sodium chloride, and sucrose, wherein the filler is present in an amount of from about 40 to about 60 wt % actives, based on the total weight of the tablet; and

water in an amount of less than about 15 wt %, based on a total weight of the tablet,

wherein:

the bentonite clay, sodium chloride, and sucrose are present in a weight ratio of actives of about 1:1:1, about 4:1:1, about 1:4:1, or about 1:1:4,

wherein the cleaning composition has a dissolution percentage of at least about 12% after about 5 minutes in water at a temperature of about 25° C.,

the bentonite clay is present in an amount of about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt % actives, based on the total weight of the tablet,

the sodium chloride is present in an amount of about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt % actives, based on the total weight of the tablet, and

the sucrose is present in an amount of from about 7.1 wt %, about 14.2 wt %, about 21.2 wt %, or about 28.3 wt %, based on the total weight of the tablet.

5. The tablet of claim 4 , wherein the filler is present in an amount of from about 40 to about 50 wt % actives, based on the total weight of the tablet.

6. The tablet of claim 4 , wherein the filler is present in an amount of from about 50 to about 60 wt % actives, based on the total weight of the tablet.

7. The tablet of claim 4 , wherein the tablet is formed as a briquette, a pill, a pellet, or a brick.

8. The tablet of claim 4 , wherein the tablet is formed by pressing powder into the tablet using a force.
