The invention relates to long-time stable mixtures (dispersions/emulsions) with only a slight tendency to separate, which provide effective and stable detergent components. Said mixtures contain 10 to 89.9 wt. % tenside(s), 10 to 89.9 wt. % meltable substance(s) with a melting point above 30 °C and a water solubility of less than 20 g/l at 20 °C, 0.1 to 15 wt. % of one or more solids, at least 90 wt. % of whose particles have a particle size of less than 300 νm and optionally, 0 to 15 wt. % other active agents and/or auxiliary agents.
