Abstract

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).

Claims

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 methyl or ethyl, and R² is (C_1-C₅)alkyl or (C_1-C₅)alkenyl with 0, 1, or 2 methyl and/or ethyl branches.

7. The composition of claim 3, wherein R¹ is hydrogen, methyl, or ethyl, and R² is (C_1-C5)alkyl or (C_1-C₅)alkenyl with 1, 2, or 3 methyl and/or ethyl branches.
