A liquid detergent composition consisting essentially of 0.01% to 1% by weight of a hydroxypropyl guar gum having a moles of substitution value in the range of 0.2 to 0.8 in an aqueous vehicle containing up to 40% by weight of a ternary surfactant mixture comprising a water-soluble salt of a C8-C18 alky etheneoxy ether sulphate containing from 1 to 12 moles of ethylene oxide, a water- soluble salt of a C8-C18 alkyl sulphate and a zwitterionic betaine surfactant of the formula <IMAGE> wherein R<1> represents an alkyl group of 10 to 20 carbon atoms or an amido radical of the formula R-C(O)N(H)(CH2)a- wherein R is an alkyl group of 9 to 19 carbon atoms and a is an integer from 1 to 4, R<2> and R<3> each represent an alkyl group having 1 to 3 carbon atoms and R<4> represents an alkylene or monohydroxyalkylene group of 1 to 4 carbon atoms, the weight ratio of alkyl sulphate to alkyl etheneoxy ether sulphate being from 1:29 to 29:1, the concentration of the said betaine being not more than 5% by weight of the composition and the said composition exhibiting improved grease soil foam stability as compared to the same composition without the said guar gum. |
