Abstract:
A granular detergent composition comprising:(A) a linear alkylbenzene sulfonate surfactant; (B) a mid-chain branched surfactant, wherein the weight ratio of said linear alkylbenzene sulfonate surfactant to said mid-chain branched surfactant is from about 1:3 to about 4:1; (C) a linear alkyl sulfate surfactant, wherein the weight ratio of said linear alkylbenzene sulfonate surfactant to said linear alkyl sulfate surfactant is from about 2:1 to about 20:1; (D) up to about 5% by weight of an alkyl ethoxylate surfactant; and (E) up to about 5% by weight of an alkyl ethoxylated sulfate surfactant; wherein said mid-chain branched surfactant has the formula Abâ€”Xâ€”B â€ƒwherein (a) Ab is a hydrophobic C9 to C22, mid-chain branched alkyl moiety having: (1) a longest linear carbon chain attached to the â€”Xâ€”B moiety in the range of from 8 to 21 carbon atoms; (2) one or more C1-C3 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 2 carbon, counting from carbon #1 which is attached to the â€”Xâ€”B moiety, to position &ohgr;âˆ’2 carbon, the terminal carbon minus 2 carbons; and (4) the surfactant composition has an average total number of carbon atoms in the Abâ€”X moiety in the above formula within the range of greater than 14.5 to about 18; (b) B is a hydophilic moiety selected from the group consisting of sulfates, sulfonates, amine oxides, polyoxyalkylene, alkoxylated sulfates, polyhydroxy moieties, phosphate esters, glycerol sulfonates, polygluconates, polyphosphate esters, phosphonates, sulfosuccinates, sulfosuccaminates, polyalkoxylated carboxylates, glucamides, taurinates, sarcosinates, glycinates, isethionates, dialkanolamides, monoalkanolamides, monoalkanolamide sulfates, diglycolamides, diglycolamide sulfates, glycerol esters, glycerol ester sulfates, glycerol ethers, glycerol ether sulfates, polyglycerol ethers, polyglycerol ether sulfates, sorbitan esters, polyalkoxylated sorbitan esters, ammonioalkanesulfonates, amidopropyl betaines, alkylated quats, alkyated/polyhydroxyalkylated quats, alkylated quats, alkylated/polyhydroxylated oxypropyl quats, imidazolines, 2-yl-succinates, sulfonated alkyl esters, and sulfonated fatty acids; and (c) X is â€”CH2â€”.
