    • The invention provides a surfactant system, for use in household detergent compositions, which is a mixture of:



      (i) at least one sulfonate-functionalized alkyl polyglycoside of general formula (I):

      R—O-(G)n-(D)  (I)

      in which:

      R represents a straight or branched chain monovalent hydrocarbyl radical having from 6 to 22 carbon atoms; G represents a residue of a reducing saccharide, connected to R—O by means of an ethereal O-glycosidic bond; n represents a number from 1 to 10; and D represents a

      —CH2CH(OH)CH2—SO3M group connected to an oxygen atom of G, where M is selected from H or a monovalent cation selected from Na, K, or NH4;

      and

      (ii) at least one ethoxylated fatty acid sorbitan ester of general formula (II):

      Sorb-(EOn1R1)(EOn2R2)(EOn3R3)(EOn4R4)  (II)

      in which:

      Sorb represents a residue obtained by removing four hydroxyl H atoms from sorbitan; EO represents an ethyleneoxy group; R1, R2, R3 and R4 are each independently selected from H or a —C(O)R5 group in which R5 is selected from straight or branched chain monovalent hydrocarbyl radicals having from 8 to 22 carbon atoms and mixtures thereof (provided that at least one of R1 to R4 is —C(O)R5); n1, n2, n3 and n4 each independently represent average values from 0 to 10; and the total [n1+n2+n3+n4] has an average value from 4 to 30;

      and in which the weight ratio of (i):(ii) in the mixture ranges from 5:1 to 1:5.
