Abstract

Lavatory treatment devices comprise a lavatory treatment composition which includes:
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 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;
0.01-25% wt. of an organic solvent constituent, which is liquid at room temperature (20° C.); 0.1-25% wt. of a detersive surfactant constituent; optionally a co-adhesion promoter constituent, preferably based on one or more oxyalkylenated compounds; further optionally one or more further optional constituents which may impart a further aesthetic or technical benefit to the said lavatory treatment compositions; and, to 100% wt. of water.

Preferably the lavatory treatment compositions of the lavatory treatment devices are ringing gels.

First claim

The invention claimed is:

1. A lavatory dispensing device comprising a 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 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;
1-25% wt. of an organic solvent constituent, which is liquid at room temperature (20° C.);
0.5-25% wt. of at least one detersive surfactant constituent which includes at least one cationic detersive surfactant of formula (a):

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, preferably Cl, Br or I,

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, preferably Cl, Br or I
to 100% wt. of water;
optionally a co-adhesion promoter constituent;
and, further optionally one or more further optional constituents which may impart a further aesthetic or technical benefit to the said lavatory treatment compositions.

2. A device according to claim 1 , wherein in the fatty alcohol polyglycol ether of formula (I), R is a residue of a C 12 -C 24 fatty alcohol having at least one unsaturated bond.

3. A device according to claim 1 , wherein in the fatty alcohol polyglycol ether of formula (I), R is a residue of a C 12 -C 24 fatty alcohol having is monounsaturated.

4. A device according to claim 1 , wherein the said composition is a ringing gel.

5. A device according to claim 1 , wherein the organic solvent constituent comprises a polyhydroxy organic solvent and at least one other organic solvent.

6. A device 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 method for treating a lavatory appliance comprising the steps of:
mounting a lavatory dispensing device according to claim 1 to a lavatory appliance, wherein the lavatory treatment composition is in the path of flowing water, which impinges upon the lavatory treatment compositions to form a lavatory treatment liquid, and,
operating the lavatory appliance to dispense a flow of water which impinges on the lavatory treatment composition in the path of flowing water thereby forming a lavatory treatment liquid which treats the lavatory appliance.

8. A lavatory dispensing device according to claim 1 , wherein the co-adhesion promoter constituent is one or more oxyalkylenated compounds.

9. A device according to claim 6 , wherein:
(a) the ratio (in % wt.) of polyhydroxy organic solvent:other solvents of the organic solvent constituent is in the range of about 4.5-10:1; 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.

10. A device according to claim 6 , 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 7-18:1; 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.

11. A device 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
