Dissolvable Toilet Brush Formulations
Formulations for dissolvable solid unit dose toilet cleaning compositions containing an anionic surfactant, a carbonate or bicarbonate salt, a water-soluble filler and an organic acid, wherein the ratio of anionic surfactant to filler is 1:6 to 5:1. The filler includes clay, a sugar or a salt. The solid unit dose can be a tablet or compressed solid that engages with a wand to clean a toilet. The solids dissolve and can be flushed after use.
1 . A solid unit dose toilet cleaning composition comprising
an anionic surfactant;
a carbonate or bicarbonate salt;
a water-soluble filler comprising a clay, a sugar, or a salt; and
an organic acid,
wherein the ratio of anionic surfactant to filler is 1:6 to 5:1.
2 . The unit dose toilet cleaning composition of claim 1 , wherein the water-soluble filler is about 10% to about 70% by weight of the cleaning composition.
3 . The unit dose toilet cleaning composition of claim 1 , wherein the filler comprises bentonite clay.
4 . The unit dose toilet cleaning composition of claim 1 , wherein the anionic surfactant is selected from Sodium Dodecylbenzenesulfonate, Sodium Cocoyl Isethionate, Sodium Olefin Sulphonate, and combinations thereof.
5 . The unit dose toilet cleaning composition of claim 1 , wherein the organic acid comprises about 1% to about 30% by weight of the cleaning composition.
6 . The unit dose toilet cleaning composition of claim 1 , wherein the organic acid consists of glycolic acid or citric acid.
7 . The unit dose toilet cleaning composition of claim 1 , wherein the unit dose is a compressed solid.
8 . The unit dose toilet cleaning composition of claim 7 , wherein the unit dose has a dissolution rate of at least about 0.1 g/min minute when submerged in water without agitation.
9 . The unit dose toilet cleaning composition of claim 1 , wherein the unit dose weighs about 2 to about 3 grams.
10 . A dissolvable toilet cleaning tablet comprising
an anionic surfactant;
a carbonate or bicarbonate salt;
filler; and
an organic acid,
wherein the tablet has a dissolution rate of at least about 0.1 g/minute when submerged in water without agitation.
11 . The dissolvable toilet cleaning tablet of claim 10 , wherein the ratio of anionic surfactant to filler is 1:6 to 5:1.
12 . The dissolvable toilet cleaning tablet of claim 10 , wherein the tablet has a hardness of at least 15 N.
13 . The dissolvable toilet cleaning tablet of claim 10 , wherein the tablet has height of about 0.5 cm to about 10 cm.
14 . The dissolvable toilet cleaning tablet of claim 10 , wherein the tablet has a hardness greater than 30 N.
15 . The dissolvable toilet cleaning tablet of claim 10 , 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.
16 . A kit comprising at least one dissolvable toilet cleaning tablet of claim 15 and a wand member.
17 . A solid toilet cleaning composition comprising
about 5% to about 50% by weight anionic surfactant;
about 10% to about 80% by weight filler selected from clay, sugars, and water-soluble salts;
about 5-20% by weight of a carbonate or bicarbonate salt; and
about 1% to about 30% by weight of an organic acid,
wherein at least 12% by weight of the tablet dissolves after 5 minutes submerged in water.
18 . The solid toilet cleaning composition of claim 17 , wherein the ratio of anionic surfactant to filler is 1:6 to 5:1.
19 . The solid toilet cleaning composition of claim 17 , wherein the organic acid is selected from citric acid and/or glycolic acid.
20 . The solid toilet cleaning composition of claim 17 , wherein the solid weighs about 2 to about 3 grams.
