Abstract

The present invention relates to cleaners for hard surfaces which comprise surfactants and also phosphoric acid esters of a polyether-modified alkyl alcohol, and to the method of use thereof for cleaning hard surfaces and for generating shine on a hard surface.

First claim

What is claimed is:

1. A cleaner for hard surfaces, comprising:
a) 0.1 to 3% by weight of at least one phosphoric acid ester of a polyether-modified alkyl alcohol or salt thereof, wherein the phosphoric acid ester of a polyether-modified alkyl alcohol has the general Formula 1:

wherein R 1 , R 2 , R 3 and R 4 may be the same or different and are selected from R—O—(SO) a -(EO) b —(PO) c —(BO) d — and —OH,
wherein

EO=—CH 2 —CH 2 —O—,
PO=—CH(CH 3 )—CH 2 —O—, and
BO=—CH(CH 2 CH 3 )—CH 2 —O—,
wherein a=1 to 20, b=1 to 100, c=0 to 10, d=0 to 10, and R is selected from branched or linear, saturated or unsaturated alkyl groups containing 8 to 10 carbon atoms
with the proviso that at least one of the groups R 1 , R 2 , R 3 and R 4 are not OH; and
b) at least one surfactant that is not the at least one phosphoric acid ester of a polyether-modified alkyl alcohol or salt thereof.

2. A cleaner for hard surfaces comprising at least one surfactant and at least one phosphoric acid ester of a polyether-modified alkyl alcohol obtainable by a method comprising the method steps of
A) providing at least one branched or linear, saturated or unsaturated alkyl alcohol containing 8 to 20 carbon atoms,
B) reacting with, in relation to the at least one alkyl alcohol, 2.2 to 10 mol, of styrene oxide at a temperature from 80 to 150° C. and a pressure from 0.4 to 1.2 bar,
C) reacting with, in relation to the at least one alkyl alcohol, 3 to 20 mol of ethylene oxide at a temperature from 80 to 130° C. and a pressure from 0.5 to 6.0 bar,
D) reacting with, in relation to the at least one alkyl alcohol, 0 to 10 mol of propylene oxide at a temperature from 80 to 130° C. and a pressure from 0.5 to 6.0 bar,
E) reacting with, in relation to the at least one alkyl alcohol, 0 to 10 mol of butylene oxide at a temperature from 80 to 130° C. and a pressure from 0.5 to 6.0 bar,
F) reacting with, in relation to the at least one alkyl alcohol, 0.1 to 1.0 mol of polyphosphoric acid P 4 O 10 at a temperature from 50 to 110° C. and a pressure from 0.4 to 1.2 bar, and where appropriate
H) purifying the obtained phosphoric acid ester.

3. The cleaner as claimed in claim 1 , wherein the agent comprises the at least one phosphoric acid ester of a polyether-modified alkyl alcohol in an amount from 0.3 to 0.9% by weight.

4. The cleaner as claimed in claim 1 , wherein the agent comprises the at least one phosphoric acid ester of a polyether-modified alkyl alcohol in an amount approximately 0.6% by weight.

5. The cleaner as claimed in claim 1 , wherein the agent is present in solid form.

6. The cleaner as claimed in claim 1 , wherein the agent is present in liquid form.

7. The cleaner as claimed in claim 1 , wherein the at least one surfactant is selected from the group consisting of: non-ionic surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, and mixtures thereof.

8. The cleaner as claimed in claim 1 , wherein the at least one surfactant is selected from the group consisting of non-ionic, anionic surfactants, and mixtures thereof.

9. The cleaner as claimed in claim 1 , wherein further comprising at least component selected from the group consisting of acids, bases, organic solvents, salts, complexing agents, fillers, builders, bleaching agents, bleach activators, auxiliaries and additives, and mixtures thereof.

10. The cleaner as claimed in claim 1 , wherein the cleaner is a liquid aqueous cleaner.

11. The cleaner as claimed in claim 1 , wherein the cleaner is a cleaner in powder form.

12. The cleaner as claimed in claim 1 , wherein the pH value of the cleaner is 5 to 11.5.

13. The cleaner as claimed in claim 1 , wherein the pH value of the cleaner is 7 to 11.3.

14. A method for generating shine on a hard surface, comprising applying onto a surface the cleaner of claim 1 .

15. The method of claim 14 , further comprising rubbing the cleaner on the surface.
