Aqueous dispersions (D) of a wax (W) dispersed in the aqueous phase by means of a dispersant (B), wherein in (D) the wax (W) is (A) an oxidized hydrocarbon wax or a mixture of oxidized hydrocarbon waxes or a mixture or (A) and at least one non-oxidized hydrocarbon wax (P), the acid number of which is>/=5, and the dispersant (B) is a non-ionogenic, anionic, cationic or amphoteric surfactant or a mixture of two or more of these surfactants, which displays an HLB>/=7, and the dispersion (D) optionally contains at least one protective colloid (C), at least one agent (E) for pH-adjustment, at least one antifreeze agent (F) and/or at least one preserving agent (D), but is substantially free of other waxes than (A) and (P) and of other surfactants than (B) and (C), are eminently suitable as wet lubricants that are very stable to temperature modifications and to high electrolyte concentrations, especially as occurring in pretreatment and in dyeing of cellulosic substrates. |
