Claims19
A method for washing clothing, comprising washing clothing with a detergent liquid having a pH of 3.5 or more and 8.5 or less at 20° C. obtained by mixing the following component (A) and component (B), and water having a hardness:
- component (A):
- an internal olefin sulfonate including an internal olefin sulfonate having 15 or more and 24 or less carbon atoms with the sulfonate group at position 2 or higher and position 4 or lower (IO-1S) and an olefin having 15 or more and 24 or less carbon atoms with the sulfonate group at position 5 or higher (IO-2S);
- and
- component (B):
- protease.
A method for enhancing a detergent activity of the following component (B), wherein, at the time of washing clothing with a detergent liquid having a pH of 3.5 or more and 8.5 or less at 20° C. obtained by mixing the component (B) and water having a hardness, the following component (A) is present in the detergent liquid:
- component (A):
- an internal olefin sulfonate having 15 or more and 24 or less carbon atoms with the sulfonate group at position 2 or higher and position 4 or lower and an olefin having 15 or more and 24 or less carbon atoms with the sulfonate group at position 5 or higher;
- and
- component (B):
- protease.
