Polishes for metal surfaces containing cationic emulsifiers, and cationic emulsifiers contained therein

Polishes for metal surfaces, based on dispersions, in organic solvents, of waxes and fluorinated materials selected from fluoroolefin copolymers and perfluoropolyoxyalkylene oils, wherein said polishes comprise a cationic emulsifier of general formula:

• R[--L--Q.sup.+ X.sup.- ].sub.t (I)
• where:
• R is a chain of perfluorooxyalkylene units containing from 1 to 3 carbon atoms, having an average molecular weight ranging from 400 to 2,000;
• L is a divalent organic group;
• t=1 or 2;
• Q=a polar organic group comprising N or P atoms as positive charge carriers, and having formula:
• ##STR10## A.sup.+ =a N or P atom;
• R.sub.1, R.sub.2, R.sub.3, like or different from one another, are alkyl groups containing from 1 to 12 carbon atoms, or, when A.sup.+ is P, they can be also aryl groups, or Q is an aromatic or aliphatic ring, either saturated or unsaturated, containing N or P atoms as positive charge carrier directly bound to the L group, in which such ring can optionally contain alkyl substituents and other heteroatoms selected from O and S;
• X.sup.- =anion.
