CLAIMS

What is claimed is:

1. A composition comprising at least about 50 wt% of a mixture of at least two compounds of Formula I:


wherein R1 is hydrogen, methyl, or ethyl;

R2 is (Ci_Cn)alkyl or (Ci_Cn)alkenyl having 0, 1, 2, or 3 (d_C3)alkyl branches, wherein branching occurs on carbon atoms that are within 40% of the nonfunctionalized terminus of the longest carbon chain;

m is 5-37 and n is 1-33, wherein m+n is 6-38;

Y is null, or Wp;

W is selected from the group consisting of ethylenoxy, propylenoxy, butylenoxy, and mixtures thereof;

p is 1 to 30;

Z is a hydrophilic moiety selected from the group consisting of hydroxy, carboxylate, sulfate, disulfate, sulfonate, disulfonate, glycerol ester sulfonate, amine, monoalkylamine, dialkylamine, amine oxide, a polyhydroxy moiety, a phosphate ester, glycerol sulfonate, polygluconate, a polyphosphate ester, phosphonate, sulfosuccinate, sulfosuccaminate, glucamide, taurinate, sarcosinate, glycinate, isethionate, dialkanolamide, monoalkanolamide, monoalkanolamide sulfate, diglycolamide, diglycolamide sulfate, a glycerol ester, a glycerol ester sulfate, a glycerol ether, a glycerol ether sulfate, a polyglycerol ether, a polyglycerol ether sulfate, sorbitan ester, an alkylpolyglucoside, urea, ammonioalkanesulfonate, amidopropyl betaine, an allylated quat, an alkyated/polyhydroxyalkylated quat, an alkylated quat, an alkylated/polyhydroxylated oxypropyl quat, a glycerol ester quat, a glycol amine quat, imidazoline, alken-2-yl-succinate, a sulfonated alkyl ester, and a sulfonated fatty acid;

wherein with respect to at least one of the compounds: when R1 is H, then R2 has 1, 2, or 3 (Ci_ C3)alkyl branches and when R1 is methyl or ethyl then R2 has 0, 1, or 2 (Ci_C3)alkyl branches.

2. The composition of claim 1, wherein with respect to the at least two of the compounds: when R1 is H, then R2 has 1, 2, or 3 (Ci_C3)alkyl branches and when R1 is methyl or ethyl then R2 has 0, 1, or 2 (Ci_C3)alkyl branches.

3. The composition of claim 2, wherein the composition contains less than about 2 wt% of secondary hydroxy compounds.

4. The composition of claim 3, wherein m is 7-27 and n is 1-23, wherein m+n is 8- 28.

5. The composition of claim 3, wherein the mixture is present in an amount of at least about 75 wt%, based on the total weight of the composition.

6. The composition of claim 3, wherein R1 is hydrogen, methyl, or ethyl, and R2 is (Ci_C5)alkyl or (Ci_C5)alkenyl with 1, 2, or 3 methyl and/or ethyl branches.

7. The composition of claim 3, wherein Z is selected from the group consisting of hydrophilic moiety selected from the group consisting of hydroxy, glycerol ether, polyglycerol ether, polyglycoside, sulfate, sulfonate, glycerol ether, amine, monoalkylamine, dialkylamine, amine oxide, monoalkanolamide, amidopropyl betaine, and an alkylated quat.

8. The composition of claim 3, wherein the omega- 1 branched compounds are present in an amount of about 1 wt% to about 40 wt%, based on the total weight of near terminal-branched compounds.

9. The composition of claim 3, further comprising a linear compound, a mid-chain branched compound, or mixtures thereof in an amount of less than about 50 wt%, based on the total weight of the composition.

10. The composition of claim 3, wherein at least one of the compounds is selected from the group consisting of: 7-methyldecyl sulfate, 8-methyldecyl sulfate, 9-methylundecyl sulfate, 10-methyldodecyl sulfate, 11-methyltridecyl sulfate, 12-methyltetradecyl sulfate, 10-methyltetradecyl sulfate, 10-ethyltetradecyl sulfate, 15-methylheptadecyl sulfate, 16-methyloctadecyl sulfate, 13-methylheptadecyl sulfate, 17-nonadecyl sulfate, 18-methylicosyl sulfate, 18-propylicosanol, 19-methylhenicosyl sulfate, 20-methyldocosyl sulfate, 21-methyltricosyl sulfate, 22-methyltetracosyl sulfate, 11 -methyl tetradecylsulf ate, 12-methyltridecylsulfate, 10-methyltetradecanol sulfate, 12-methyltetradecanol, 12-
