Abstract
When added thereto, certain cationic alkylammonium surfactant compounds, e.g., C.sub.12 H.sub.25 N(CH.sub.3).sub.3 Cl, enhance the leveling activity of known fluorophosphate leveling agents, e.g., ##STR1## where (CF.sub.2).sub.n represents a mixture of groups with C.sub.4 -C.sub.14 carbons, in floor polishes.
Claims11
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.
