    摘要： A detergent composition includes:



    A. a co-polymer of diallyldimethylammonium chloride and acrylic acid in an amount of from about 0.05 to about 1 weight percent actives;
    B. sodium and/or potassium chloride in an amount of greater than about 0.5 up to about 5 weight percent actives;
    C. a surfactant component in an amount of from about 8 to about 30 weight percent actives and comprising:

    (1) an alcohol ethoxy sulfate in an amount of from about 0 to about 60 weight percent actives;
    (2) an alkoxylated alcohol in an amount of from about 0 to about 90 weight percent actives;
    (3) a linear alkylbenzene sulfonate in an amount of from about 0 to about 90 weight percent actives;
    wherein at least two of said (1) alcohol ethoxy sulfate, said (2) alkoxylated alcohol, and said (3) linear alkylbenzene sulfonate are present in an amount of greater than zero; and


    D. water.

    摘要： 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.
