Abstract

Self-adhesive lavatory treatment compositions comprise an adhesion promoter based on a fatty alcohol polyglycol ether as may be represented by the following structural formula (I):

R—O CH 2 —CH 2 —O n H  (I)

within which, R is an C 12 -C 24 aliphatic mono- or poly-alkene moiety, and n has a value of from 1 to 50, an organic solvent constituent, a surfactant, and water.

First claim

The invention claimed is:

1. A self-adhesive lavatory treatment composition which comprises:
up to 50% wt. of an adhesion promoter constituent based on a fatty alcohol polyglycol ether as may be represented by the following structural formula (I):
R—O CH 2 —CH 2 —O H n   (I)

within which,
R is an C 12 -C 24 aliphatic mono- or poly-alkene moiety and which includes at least one unsaturation in the moiety, and
n has a value of from 1 to 50;
1-25% wt. of an organic solvent constituent, which is liquid at room temperature (20° C.);
at least 25% wt. of water;
0.5-25% wt of a detersive cationic surfactant constituent according to structure (a) and/or structure (b):

in which:
R is C 8 -C 22 alkyl;
R 1 , R 2 , R 3 and R 4 are independently selected from the group consisting of: H, and the further group,

in which R 13 is C 8 -C 22 alkyl with the proviso that R 1 , R 2 , R 3 and R 4 are not all H;
and X is a halogen,

in which:
R is C 8 -C 22 alkyl;
R 5 , R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are independently selected from the group consisting of: H, and the further group,

in which R 13 is C 8 -C 22 alkyl, with the proviso that R 5 , R 6 , R 7 , R 8 , R 9 , R 10 and R 11 are not all H;
and X is a halogen;
optionally a co-adhesion promoter constituent;
wherein in use, the said self-adhesive lavatory treatment compositions may be applied and adhered to a dry or wetted ceramic surface, especially the interior sidewall in a toilet bowl or other lavatory appliance, and wherein the said self-adhesive lavatory treatment compositions is retained adhered to the said surface following a plurality of flushes of water impinging upon the adhered self-adhesive lavatory treatment compositions.

2. A self-adhesive lavatory treatment composition according to claim 1 , wherein in the fatty alcohol polyglycol ether of formula (I), wherein R is monounsaturated.

3. A self-adhesive lavatory treatment composition according to claim 1 , wherein the said composition is a ringing gel.

4. A dispensing device, which comprises a quantity or mass of the self-adhesive lavatory treatment composition according to claim 1 .

5. A self-adhesive lavatory treatment composition according to claim 1 , wherein the organic solvent constituent comprises a polyhydroxy organic solvent and at least one other organic solvent.

6. A self-adhesive lavatory treatment composition according to claim 5 , wherein:
(a) the ratio (in % wt.) of polyhydroxy organic solvent:other solvents of the organic solvent constituent is in the range of about 4-12:1; and/or
(b) the ratio (in % wt.) of polyhydroxy organic solvent:mineral oil is in the range of about 5-20:1; and/or
(c) the ratios (in % wt.) of water:organic solvent constituent is in the range of about 5-20:1 and/or
(d) the ratios (in % wt.) of water:polyhydroxy organic solvent constituent is in the range of about 5-25:1.

7. A dispensing device which comprises a quantity of a self-adhesive lavatory treatment composition according to claim 1 , which dispensing device is adapted to extrude a quantity of the self-adhesive lavatory treatment composition onto a lavatory appliance, and which dispensing device is adapted to be removed prior to formation of a lavatory treatment liquid.

8. A method for treating a lavatory appliance comprising the steps of:
applying a self-adhesive lavatory treatment composition according to claim 1 directly to a part of a lavatory appliance wherein the adhered self-adhesive lavatory treatment composition is in the path of flowing water, which impinges upon the adhered self-adhesive lavatory treatment compositions and slowly erodes the same, and,
operating the lavatory appliance to dispense a flow of water which impinges on the self-adhesive lavatory treatment composition is in the path of flowing water thereby forming a lavatory treatment liquid which treats the lavatory appliance.

9. A self-adhesive lavatory treatment composition according to claim 1 which consists essentially of:
up to 50% wt. of an adhesion promoter constituent based on a fatty alcohol polyglycol ether as may be represented by the following structural formula (I):

within which, R is an C 12 -C 24 aliphatic mono- or poly-alkene moiety, and n has a value of from 1 to 50 and, which include at least one unsaturation in the moiety;
1-25% wt. of an organic solvent constituent, which is liquid at room temperature (20° C.);
0.5-25% wt. of a detersive cationic surfactant constituent constituent according to structure (a) and/or structure (b):

in which:
R is C 8 -C 22 alkyl;
