Abstract

A dissolvable toilet cleaning solid tablet includes an anionic surfactant; virgin soap pellets; and borax, and desirably, a carbonate or bicarbonate salt; and an acid. The borax comprises about 0.5% to about 10% by weight of the composition, and the virgin soap pellets comprise about 12% to about 25% by weight of the composition.

Claims (39)

1. A solid unit dose of a toilet cleaning composition comprising:

an anionic surfactant;

virgin soap pellets;

a carbonate or bicarbonate salt;

an acid; and

borax,

wherein the virgin soap pellets comprise 18% to about 35% by weight of the toilet cleaning composition.

2. The solid unit dose of claim 1 , wherein the borax comprises about 0.5% to about 10% by weight of the toilet cleaning composition.

3. The solid unit dose of claim 1 , wherein the virgin soap pellets comprise about 20% to about 35% by weight of the toilet cleaning composition.

4. The solid unit dose of claim 1 , wherein the virgin soap pellets comprise about 55% to about 90% by weight of a soap mixture, and the soap mixture further comprises about 0.5% to 5% by weight free fatty acids, glycerin, and one or more chelating agents or stabilizers.

5. The solid unit dose of claim 4 , wherein the soap mixture further comprises monovalent salts of tallow and palm kernel fatty acids.

6. The solid unit dose of claim 1 , wherein the anionic surfactant is selected from the group consisting of sodium dodecylbenzenesulfonate, sodium cocoyl isethionate, sodium olefin sulphonate, and combinations thereof.

7. The solid unit dose of claim 1 , wherein the acid comprises about 1% to about 30% by weight of the toilet cleaning composition.

8. The solid unit dose of claim 1 , wherein the acid consists of glycolic acid or citric acid.

9. The solid unit dose of claim 1 , wherein the unit dose comprises an indentation in at least one of its surfaces that is adapted to receive and engage a wand.

10. The solid unit dose of claim 1 , wherein the unit dose weighs about 25 to about 45 grams.

11. The solid unit dose of claim 1 , wherein time to breakage of the unit dose when submerged in toilet water is delayed compared to a unit dose having no boron compound.

12. The solid unit dose of claim 1 , wherein the toilet cleaning composition is in the form of at least one of powders or pellets that are compressed into the solid unit dose.

13. A dissolvable toilet cleaning tablet comprising:

an anionic surfactant;

virgin soap pellets; and

one or more boron compounds,

wherein the virgin soap pellets comprise 18% to about 35% by weight of the tablet,

wherein greater than 20% of the tablet dissolves when placed in 700 ml of water for 10 minutes with no agitation, and

wherein the tablet has a top surface, a bottom surface, and a height extending from the top surface to the bottom surface, the top surface having an indentation adapted to receive and engage with a wand member.

14. The dissolvable toilet cleaning tablet of claim 13 , wherein the tablet has a hardness of 15 N or greater than 15 N.

15. A package comprising the dissolvable toilet cleaning tablet of claim 13 and a wand member.

16. A solid toilet cleaning composition comprising:

about 5% to about 50% by weight anionic surfactant;

about 5-20% by weight of a carbonate or bicarbonate salt;

about 1% to about 30% by weight of an acid;

18% to about 35% by weight virgin soap pellets; and

about 0.5% to about 10% by weight of a boron compound,

wherein the solid toilet cleaning composition is provided as a unit dose, and

wherein time to breakage of the unit dose when submerged in toilet water is delayed compared to a unit dose having no boron compound.

17. The solid toilet cleaning composition of claim 16 , wherein the boron compound comprises 70% or more of sodium tetraborate.

18. The solid toilet cleaning composition of claim 16 , wherein the virgin soap pellets comprise about 55% to about 90% by weight of a soap mixture, and the soap mixture further comprises about 0.5% to 5% by weight free fatty acids, glycerin, and one or more chelating agents or stabilizers.

19. The solid toilet cleaning composition of claim 18 , wherein the soap mixture further comprises monovalent salts of tallow and palm kernel fatty acids.

20. The solid toilet cleaning composition of claim 16 , wherein the unit dose has a top surface, a bottom surface, and a height extending from the top surface to the bottom surface, the top surface having an indentation from 25% to 100% of the height of the unit dose that is adapted to receive and engage with a wand member.
