Abstract:
A detergent surfactant composition comprising at least about 5% by weight of longer alkyl chain, mid-chain branched surfactant compounds of the formula:A.sup.b --X--Bwherein:(a) A.sup.b is a hydrophobic C9 to C22, total carbons in the moiety, mid-chain branched alkyl moiety having: (1) a longest linear carbon chain attached to the --X--B moiety in the range of from 8 to 21 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 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 --X--B moiety, to position .omega.-2 carbon, the terminal carbon minus 2 carbons; and (4) the surfactant composition has an average total number of carbon atoms in the A.sup.b --X moiety in the above formula within the range of greater than 14.5 to about 17.5;(b) B is a hydophilic moiety selected from sulfates, sulfonates, amine oxides, 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, allylated quats, alkyated/polyhydroxyalkylated quats, alkylated quats, alkylated/polyhydroxylated oxypropyl quats, imidazolines, 2-yl-succinates, sulfonated alkyl esters, and sulfonated fatty acids;(c) X is selected from --CH.sub.2 -- and --C(O)--; and(d) wherein A.sup.b is substantially free of geminally-substituted carbon atoms.
