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.
Claims15
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 R1, R2, R3 and R4 may be the same or different and are selected from R—O—(SO)a-(EO)b—(PO)c—(BO)d— and —OH,
- wherein
- EO=—CH2—CH2—O—,
- PO=—CH(CH3)—CH2—O—, and
- BO=—CH(CH2CH3)—CH2—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 R1, R2, R3 and R4 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.
7 more elements
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 P4O10 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.
