Abstract

Described herein is a formulation including
(A) at least one nonionic surfactant, (B) at least one graft copolymer formed from
(a) at least one graft base selected from nonionic monosaccharides, disaccharides, oligosaccharides and polysaccharides, and side chains; and
(C) a total of zero to 0.5% by weight of methylglycinediacetic acid (MGDA) and glutaminediacetic acid (GLDA) and alkali metal salts of MGDA and GLDA and a total of zero to 0.5% by weight of citric acid or an alkali metal salt of citric acid, where figures in % by weight are based in each case on a solids content of the formulation in question.

First claim

The invention claimed is:

1. A formulation comprising
(A) at least one nonionic surfactant,
(B) at least one graft copolymer formed from
(a) at least one graft base selected from nonionic monosaccharides, disaccharides, oligosaccharides and polysaccharides, and side chains, obtainable by grafting of
(b) at least one ethylenically unsaturated mono- or dicarboxylic acid and
(c) at least one compound of a general formula (I)

wherein the variables are defined as follows:
R 1 is selected from methyl and hydrogen,
A 1 is selected from C 2 -C 4 -alkylene,
R 2 are the same or different and are selected from C 1 -C 4 -alkyl,
X − is selected from halide, mono-C 1 -C 4 -alkylsulfate and sulfate; and
(C) a total of zero to 0.5% by weight of methylglycinediacetic acid (MGDA) and glutaminediacetic acid (GLDA) and alkali metal salts of MGDA and GLDA and a total of zero to 0.5% by weight of citric acid or an alkali metal salt of citric acid, wherein figures in % by weight are based in each case on a solids content of the formulation.

2. The formulation according to claim 1 , wherein compound (c) is ω-trimethylaminoethyl(meth)acrylatochloride.

3. The formulation according to claim 1 , wherein compound (A) is selected from alcohol alkoxylates and alkyl polyglycosides.

4. The formulation according to claim 1 , wherein the formulation further comprises water.

5. The formulation according to claim 1 , wherein the formulation further comprises at least one organic peroxide compound (D) or a chlorine bleach (D).

6. The formulation according to claim 1 , wherein the formulation comprises at least one acid or base.

7. The formulation according to claim 1 , wherein the formulation comprises:
a total of in a range from 20% to 99% by weight of compound (A),
a total of in a range from 1% to 40% by weight of graft copolymer (B),
based in each case on the solids content of the formulation.

8. The formulation according to claim 1 , wherein a weight ratio of compound (A) to graft copolymer (B) is in a range from 1:2 to 20:1.

9. The formulation according to claim 1 , wherein the formulation is liquid at room temperature.

10. The formulation according to claim 1 , wherein the formulation is solid at room temperature.

11. A method of using the formulation according to claim 1 , the method comprising using the formulation for cleaning or rinsing hard surfaces.

12. The method of use according to claim 11 , wherein the cleaning or rinsing is of slabs, tiles, glass, stainless steel, wood, aluminum, enamel or ceramic.

13. The method of use according to claim 11 , wherein the cleaning or rinsing is effected by hand or with an aid of a machine.

14. A process for producing the formulation according to claim 1 , the process comprising mixing at least one nonionic surfactant (A) and at least one graft copolymer (B) and optionally one or more further ingredients (E) and optionally peroxide (D) or chlorine bleach (D) with one another in one or more steps, optionally in a presence of water, and then optionally wholly or partially removing water.

15. The formulation of claim 1 , wherein methylglycinediacetic acid (MGDA) and glutaminediacetic acid (GLDA) and alkali metal salts of MGDA and GLDA is present in an amount from zero to 0.1 wt %.
