Abstract
The present invention relates to liquid detergent compositions comprising one or more block polymeric suds volume and suds duration enhancers. The block polymeric suds enhancers (suds boosters) suitable for use in the compositions of the present invention comprise one or more cationic block units and optionally one or more additional building blocks such as hydroxyl-containing units, hydrophobic group-containing units, hydrophilic group-containing units, anionic units, other cationic units, hydrogen-bonding units and zwitterionic units. The present invention further relates to methods for providing enhanced suds volume and suds duration during hand washing.
