Reduction method and surfactant compositions of the critical micelle concentration

The present invention is now a process for suppressing the amount to significantly reduce the critical micelle concentration of the anionic surfactant are used in large amounts, an anionic surfactant as a surfactant alone and to provide an overall critical micelle concentration are significantly reduced, the surfactant composition the amount of anionic surfactant is suppressed compared with the case of using. The method for reducing the critical micelle concentration of the anionic surfactant of the present invention is characterized by using a combination of cyclic lipopeptide biosurfactant to the anionic surfactant.
