Abstract:
An aqueous light duty liquid dishwashing detergent composition comprising:from 5% to 70% by weight of a surfactant system which comprises at least 10%, by weight of a branched surfactant mixture, said branched surfactant mixture comprising mid-chain branched and linear surfactant compounds, said linear compounds comprising less than 25%, by weight of the branched surfactant mixture and said mid-chain branched compounds being of the formula:A.sup.b -Bwherein:A.sup.b is a hydrophobic C9 to C18, total carbons in the moiety, mid-chain branched alkyl moiety having: (1) a longest linear carbon chain attached to the--B moiety in the range of from 8 to 17 carbon atoms; (2) one or more C.sub.1 -C.sub.3 alkyl moieties branching from this longest linear carbon chain; (3) at least one of the branching alkyl moieties is attached directly to a carbon of the longest linear carbon chain at a position within the range of position 3 carbon, counting from carbon #1 which is attached to the--B moiety, to position .omega.-2 carbons the terminal carbon minus 2 carbons; and (4) the surfactant composition has an average total number of carbon atoms in the A.sup.b moiety in the above formula within the range of greater than 12 to 14.5; and B is a hydrophilic moiety selected from the group consisting of OSO.sub.3 M, (EO/PO)mOSO.sub.3 M, (EO/PO)mOH and mixtures thereof, wherein EO/PO are alkoxy moieties selected from the group consisting of ethoxy, propoxy, and mixtures thereof, and in is at least 0.01 to 30; andfrom 1% to 10% by weight of a suds booster/stabilizer selected from the group consisting of betaine surfactants, alkanol fatty acid amides, amine oxide semi-polar nonionic surfactants, C.sub.8 -C.sub.22 alkylpolyglycosides, and combinations thereof.
