## Abstract

A composition includes a fluorinated or perfluorinated organic solvent, and a fluorinated surfactant of the general formula (1): [Formula should be inserted here] Rf is a perfluoroalkyl group having 1-6 carbon atoms. Each occurrence of R1 and R2 is independently H or CH3, n is 1-3, and x is 1-3.

## Claims

### Claim 1

A composition comprising:
a fluorinated or perfluorinated organic solvent; and
a fluorinated surfactant of the general formula (1):
where Rf is a perfluoroalkyl group having 1-6 carbon atoms; each occurrence of R1 and R2 is independently H or CH3; n is 1-3; and x is 1-3.

### Claim 2 (depends on 1)

The composition according to claim 1, wherein the fluorinated surfactant is present in the composition in an amount of between 0.01 and 1 wt. % based on the total weight of the composition.

### Claim 3 (depends on 1)

The composition according to claim 1, wherein the organic solvent comprises a non-flammable fluorinated or perfluorinated organic solvent.

### Claim 4 (depends on 1)

The composition according to claim 1, wherein the fluorinated or perfluorinated organic solvent comprises a primary organic solvent that is present in the composition at greater than 50 wt. % based on the total weight of the composition, and wherein the primary organic solvent comprises a hydrofluoroether, hydrofluorocarbon, hydrofluoroolefin, hydrochlorofluoroolefin, fluoroketone, perfluoroketone, or combinations thereof.

### Claim 5 (depends on 4)

The composition according to claim 4, wherein the primary organic solvent comprises a hydrofluoroether.

### Claim 6 (depends on 5)

The composition according to claim 5, wherein the primary organic solvent comprises a segregated hydrofluoroether.

### Claim 7 (depends on 1)

The composition according to claim 1, wherein the fluorinated or perfluorinated organic solvent is present in the composition in an amount of at least 95 wt. %, based on the total weight of the composition.

### Claim 8 (depends on 1)

The composition according to claim 1, further comprising a co-solvent.

### Claim 9 (depends on 8)

The composition according to claim 8, wherein the co-solvent comprises an alcohol.

### Claim 10 (depends on 9)

The composition according to claim 9, wherein the co-solvent is present in the composition in an amount of between 1 and 10 wt. %, based on the total weight of the composition.

### Claim 11 (depends on 1)

The composition according to claim 1, further comprising a second fluorinated surfactant according to general formula (2):
where m is 1-3, each occurrence of R4 is H or CH3, R3 is H or an alkyl group, and Rf is a perfluoroalkyl group having 1-6 carbon atoms.

### Claim 12 (depends on 11)

The composition according to claim 11, wherein the second surfactant is present in the composition in an amount of between 0.01 and 1 wt. %, based on the total weight of the composition.

### Claim 13 (depends on 1)

The composition according to claim 1, wherein, Rf in general formula (1) is a perfluoroalkyl group having 4 carbon atoms and at least one of R1 and R2 is H.

### Claim 14 (depends on 1)

A process for removing contaminants from a substrate, the process comprising contacting the substrate with a composition according to claim 1.
