The composition will incorporate a polycarboxylic polymeric thickener, especially a cross-linked polyacrylic acid. Also present will be a structurant which can either be up to 2% alumina or up to 0.05% hectorite clay. Also present in the composition will be from 0.01 to 20% of an alkyl polyglycoside which ensures improved cleaning and clarity.Other References
