- a) the tetraalkylammonium halides, selected from the group consisting of behenyltrimethylammonium chloride and dimethyldistearylammonium chloride;
- b) a quaternary ammonium salt of formula: ##STR9## in which R denotes a mixture of C.sub.13 -C.sub.21 alkenyl and/or alkyl radicals derived from tallow fatty acids,
- c) stearamidopropyldimethyl(myristylacetate)ammonium chloride.
- 6. Dispersion according to claim 1, characterized in that the compound of formula (I) is present in concentrations between 0.01 and 15% by weight with respect to the total weight of the dispersion and in that the cationic surface-active agent of formula (II) is present in concentrations between 0.01 and 15% by weight.
