Abstract
According to the present invention, provided is a surfactant composition having excellent fluidity after long-term storage at a low temperature (5 degrees Celsius) and excellent foamability when diluted. It is considered that the reason why the composition of the present invention has excellent fluidity after long-term storage at a low temperature (5 degrees Celsius) and excellent foamability when diluted is because the sulfate surfactant has a predetermined amount of oxypropylene groups, thereby suppressing crystallization.
