A liquid detergent contains anionic and/or non-ionic surfactants, as well as further usual components of liquid detergents, if required. The liquid detergent contains at least one carboxylic acid ester. The carboxylic acid esters suitable as viscosity regulators are derived from carboxylic acids or from hydroxycarboxylic acids with 3 to 22 carbon atoms and from alcohols with 1 to 18 carbon atoms which contain 1 to 3 OH groups. Glycerin monostearate and myristyl lactate are particularly suitable carboxylic acid esters.
