Rhamnolipids and/or sophorolipids can be used in coating compositions for improvement of the speed of wetting of pulverulent formulation constituents in such compositions, which leads to a reduction in dust nuisance during incorporation thereof and to the increase in occupational safety in the production of coating compositions. Rhamnolipids and/or sophorolipids can also be used in coating compositions for obtaining improved homogeneous colour appearance of the dry paint film with regard to difference in hue, ascertained from the delta E and visual assessment.
