The present invention relates to liquid detergent compositions comprising anionic/amphoteric surfactant systems. Low addition levels of specific hydrophobically modified polyalkylene glycol wherein ratio of hydrophobically modified polyalkylene glycol to anionic surfactant is defined have been found to remarkably enhance mildness without sacrificing processibility and desired user properties. In a second embodiment, the invention relates to a method for enhancing mildness in liquid detergent compositions comprising anionic surfactant by adding said defined hydrophobically modified polyalkylene glycols.
