Abstract

A composition comprising a compound of formula (I) or (II): wherein r and q are independently integers of 1 to 3; R f is linear or branched chain perfluoroalkyl group having 1 to 6 carbon atoms; j is an integer 0 or 1, or a mixture thereof, x is 1 or 2, Z is —O— or —S—, X is hydrogen or M, and M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion is disclosed.

Claims (16)

1. A composition comprising a compound of formula (I) or (II):

wherein

r and q are independently integers of 1 to 3;

R f is linear or branched chain perfluoroalkyl group having 1 to 6 carbon atoms;

j is an integer 0 or 1, or a mixture thereof,

x is 1 or 2, or a mixture thereof

Z is —O— or —S—,

X is hydrogen or M, and

M is an ammonium ion, an alkali metal ion, or an alkanolammonium ion said composition providing water repellency, oil repellency, stain resistance, resistance to blocking and open time extension to a substrate treated therewith.

2. The composition of claim 1 wherein R f has 4 to 6 carbon atoms, and r, q and j are each 1.

3. The composition of claim 1 wherein M is an ammonium or an alkanolammonium ion.

4. The composition of claim 1 comprising a mono(fluoroalkyl) phosphate of formula (I), wherein x is 1 of about 15 to about 80 mol %, and a bis(fluoroalkyl) phosphate of formula (I) wherein x=2 of about 20 to about 85 mol %.

5. The composition of claim 1 further comprising

a) an agent providing at least one surface effect selected from the group consisting of stain repellency, stain release, soil repellency, soil release, water repellency, oil repellency, and antimicrobial protection,

b) a surfactant, pH adjuster, wetting agent, leveling agent or

c) a mixture thereof.
