Compositions comprising a near terminal-branched compound and methods of making the same
Disclosed herein are novel mixtures of near terminal-branched compounds and derivatives thereof. Further disclosed are methods of making these mixtures, and uses of these mixtures in cleaning compositions (e.g., dishcare, laundry, hard surface cleaners,) and/or personal care compositions (e.g., skin cleansers, shampoo, hair conditioners).
1. A composition comprising at least about 50 wt % of a mixture of at least two compounds selected from the group consisting of:
wherein A and B are each independently OH or O(C═O)R 7 ;
R 1 is hydrogen, methyl, or ethyl;
R 2 is (C 1- C n )alkyl or (C 1- C n )alkenyl having 0, 1, 2, or 3 (C 1- C 3 )alkyl branches, wherein when R 1 is H, R 2 has 1, 2, or 3 (C 1- C 3 )alkyl branches, and when R 1 is methyl or ethyl, R 2 has 0, 1, or 2 (C 1- C 3 )alkyl branches, and wherein branching occurs on carbon atoms that are within 40% of the nonfunctionalized terminus of the longest carbon chain;
R 3 , R 4 , and R 5 are each independently
R 7 is (C 1- C 26 )alkyl; and,
m is 5-37 and n is 1-33, wherein m+n is 6-38; and,
wherein the composition contains less than about 2 wt % of secondary hydroxy compounds.
2. The composition of claim 1 , herein m is 7-27 and n is 1-23, wherein m+n is 8-28.
3. The composition of claim 2 , wherein the mixture is present in an amount of at least about 75 wt %, based on the total weight of the composition.
4. The composition of claim 2 , wherein R 1 is hydrogen, methyl, or ethyl, and R 2 is (C 1- C 5 )alkyl or (C 1- C 5 )alkenyl with 1, 2, or 3 methyl and/or ethyl branches.
5. The composition of claim 2 , 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.
6. The composition of claim 2 , wherein the composition is free of secondary hydroxy compounds.
7. The composition of claim 2 , further comprising a linear fatty acid, a linear fatty alcohol, a mid-chain branched fatty acid, a mid-chain branched fatty alcohol, or mixtures thereof in an amount of less than about 50 wt %, based on the total weight of the composition.
8. The composition of claim 7 , wherein the linear fatty acid, the linear fatty alcohol, the mid-chain branched fatty acid, the mid-chain branched fatty alcohol, and mixtures thereof in an amount of less than about 10 wt %, based on the total weight of the composition.
9. The composition of claim 1 , wherein the moiety
is fully or partially hydrogenated.
