Therefore, if the narrow ratio is high, the coexisting components are sufficiently small, and the problem of the reduction of the detergency and the odor of the raw material hardly occurs.
The upper limit value of the narrow ratio is not particularly limited, but is preferably substantially 80% by mass or less.
