## Abstract

Care compositions for hard surfaces, which can be prepared using organopolysiloxanes which are solid at room temperature, contain fluorine groups and can change their state of aggregation reversibly on the basis of changes in temperature.

## Claims

### Claim 1

A composition for the care of hard surfaces, prepared from an aqueous emulsion, comprising a fluorine group confining organopolysiloxane which is solid at room temperature and has a melting point of from 25.degree. C. to 60.degree. C. and an emulsifier.

### Claim 2 (depends on 1)

The composition as claimed in claim 1 in which the fluorine group containing organopolysiloxane which is solid at room temperature is comprised of units of formula
R.sub.a R.sup.1.sub.b SiO.sub.(4-a-b)/2 (I)
in which
R is an identical or different monovalent hydrocarbon radical or hydrocarbon radical containing fluorine groups,
R.sup.1 is an identical or different hydrocarbon radical containing fluorine groups,
a is 0, 1, 2 or 3, and
b is 0, 1, 2 or 3,
with the proviso that the sum of a+b is less than or equal to 3 and at least one unit which contains a hydrocarbon radical containing fluorine groups is present in the organopolysiloxane comprised of units of formula (I).

### Claim 3 (depends on 1)

The composition as claimed in claim 1, wherein the organopolysiloxane is a linear organopolysiloxane which is solid at room temperature, comprised of units of formula
R.sub.3 SiO(SiR.sub.2 O).sub.x ›(SiRR.sup.1 O).sub.r (SiRR.sup.2 O).sub.s !.sub.y SiR.sub.3 (II),
in which
R.sup.2 is an identical or different monovalent hydrocarbon radical, and
R is an identical or different monovalent hydrocarbon radical or hydrocarbon radical containing fluorine groups,
R.sup.1 is an identical or different hydrocarbon radical containing fluorine groups,
r has a value from 0 to 100,
s has a value from 0 to 179,
x has a value from 0 to 300,
y has a value from 1 to 180,
and the sum of x+y is 1-300,
with the proviso that at least one radical R in formula (II) is a hydrocarbon radical having at least 18 carbon atoms, and where r=0 at least one radical R has the meaning of R.sup.1.

### Claim 4 (depends on 1)

The composition as claimed in claim 1, where the organopolysiloxane is present in amounts of 0.1% to 5.0% by weight, based on the total weight of the care composition.

### Claim 5 (depends on 1)

The composition as claimed in claim 1 which comprises water in mounts of 85% to 99.9% by weight, based on the total weight of the composition.

### Claim 6 (depends on 5)

The composition as claimed in claim 5, is free of organic solvent.

### Claim 7 (depends on 1)

A process for the care of a hard surface, comprising applying the composition as claimed in claim 1 to the hard surface.

### Claim 8 (depends on 7)

The process as claimed in claim 7, wherein the hard surfaces are those chosen from the group consisting of a metallic surface, a painted surface and a surface of plastic.

### Claim 9 (depends on 1)

The composition as claimed in claim 1, further comprising;
A. waxes that are free of silicone,
B. thickeners
C. abrasives,
D. preservatives,
E. additives selected from the group consisting of fragrances and colorants, or
F. mixtures of A, B, C, D or E.

### Claim 10 (depends on 1)

The composition as claimed in claim 1, further comprising silicones that are liquid at room temperature.

### Claim 11

A composition for the care of hard surfaces, prepared from a solution of a fluorine group containing organopolysiloxane, which is solid at room temperature, has a melting point of from 25.degree. C. to 60.degree. C., dissolved in an organic solvent.

### Claim 12 (depends on 11)

A process for the care of a hard surface, comprising; applying the composition as claimed in claim 11 to the hard surface.

### Claim 13 (depends on 12)

The process as claimed in claim 12, where the hard surface is selected from the group consisting of a metallic surface, a painted surface, and a surface of plastic.
