Claims7
A surfactant composition comprising a mixture of secondary alcohol alkoxylates comprising:
- A) from 10 to 25 mass% of a C12 compound of the following formula (1):
- wherein A is an alkylene group having 1 to 3 carbon atoms, x is 1 to 50, and m+n is 9;
- B) from 40 to 65 mass % of a C13 compound of the formula (1), where A is an alkylene group having 1 to 3 carbon atoms, x is 1 to 50, and m+n is 10;
- C) from 20 to 49.9 mass % of a C14 compound of the formula (1), where A is an alkylene group having 1 to 3 carbon atoms, x is 1 to 50, and m+n is 11;
- and
- D) a Y compound of the formula (1), where A is an alkylene group having 1 to 3 carbon atoms, x is 1 to 50, and m+n is either 8 or less and/or 12 or more, wherein 0.1 mass% ≤ MY < 5 mass% is satisfied, and MY is the content of the Y compound.
A method for producing a surfactant composition, comprising adding an alkylene oxide to a secondary alcohol mixture containing:
- 10 to 25 mass % of a C12 precursor of the following formula (2):
- where m+n is 9;
