Abstract
Abstract When added thereto, certain cationic alkylammonium surfactant compounds, e.g., C 12 H 25 N(CH 3 ) 3 Cl, enhance the leveling activity of known fluorophosphate leveling agents, e.g., ##STR1## where (CF 2 ) n represents a mixture of groups with C 4 -C 14 carbons, in floor polishes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
115 words
A leveling composition consisting essentially of a mixture of: A. at least one water-soluble cationic surfactant chosen from [RN(CH.sub.3).sub.3 ]Q, [RR'N(CH.sub.3).sub.2 ]Q and ##STR10## wherein R and R' are C.sub.8 -C.sub.18 alkyl, R" is C.sub.12 -C.sub.18 alkyl, Q is a water-solubilizing anion and q and r are integers in the range 1-25; and B. at least one anionic water-soluble polyfluoroalkyl phosphate of the formula ##STR11## wherein M is a water-solubilizing cation, y is a number of average value from 1.0 to 2.5, n is an integer from 4 to 14 and m is an integer from 1 to 16, the mole ratio of cationic A to anionic B being in the range 0.1/1 to 0.5/1.
