Abstract

The invention relates to an aqueous sanitary cleaning composition comprising a sulfamic acid in an amount of about ≤10 wt.-%, isotridecanol ethoxylate in an amount of about less than 3 wt.-%, a perfume in an amount in a range of about ≥0.2 wt.-% to ≤0.5 wt.-%, and water, wherein the wt.-% of the components are based on the total weight of the sanitary cleaning composition, and wherein the perfume comprises at least one of the compounds according to the general formulas I, II and III, and/or a compound according to the general formula IV.

First claim

The invention claimed is:

1. A method of using a sanitary cleaning composition or an aqueous sanitary cleaning solution comprising;
cleaning a sanitary surface with a composition or an aqueous solution wherein the composition comprises: sulfamic acid or sulfamic acid derivative in an amount of about ≤10 wt.-%, isotridecanol ethoxylate in an amount of about less than 3 wt.-%,
a perfume in an amount in a range of about ≥0.2 wt.-% to ≤0.5 wt.-%, wherein the perfume has one of the following formulas I, II and/or III:

and wherein R 1 is selected from the group consisting of hydrogen and C 1-5 alkyl,
and R 2 , R 3 , R 4 independently is selected from the group consisting of C 1-5 alkyl, and

a compound according to formula IV:

 and
water.

2. The method of claim 1 , wherein the composition comprises about ≥5 wt.-% to about ≤10 wt.-% based on the total weight of the composition, of sulfamic acid or a sulfamic acid derivative.

3. The method of claim 1 , wherein the composition comprises about ≥0.5 wt.-% to about <3 wt.-% based on the total weight of the composition, of isotridecanol ethoxylate.

4. The method of claim 1 , wherein R 1 is a hydrogen or a C 1-3 alkyl.

5. The method of claim 1 , wherein R 2 is a C 1-3 alkyl.

6. The method of claim 1 , wherein R 3 is a C 1-4 alkyl.

7. The method of claim 1 , wherein R 4 is a C 1-3 alkyl.

8. The method of claim 1 , wherein the composition comprises about ≥0.2 wt.-% to about ≤0.4 wt.-%, based on the total weight of the composition, perfume.

9. The method of claim 1 , wherein the composition further comprises about ≥2 wt.-% to about ≤5 wt.-%, based on the total weight of the composition, urea.

10. The method of claim 1 , wherein the composition further comprises about ≥0.5 wt.-% to about ≤3 wt.-%, based on the total weight of the composition, of a C2 to C3 alcohol.

11. The method of claim 1 , further comprising a step of diluting the composition in water to obtain the aqueous sanitary cleaning solution.
