We investigate the detergency and surface active properties of mixed surfactants. Critical micelle concentration (CMC), surface tension (γ), wettability were measured as surface active properties. In addition, based on these properties, detergency was examined. With the addition of amphoteric and nonionic to mixed anionic surfactants, CMC and γ were decreased. Addition of CAPB, which is amphoteric, showed the best property at CMC and γ. Furthermore, as the chain length of hydrocarbon in alkyl glucosides was increased, the CMC and γ were enhanced. Detergency was measured at various temperatures. The cleaning performance was enhanced by increasing washing temperature. Furthermore, detergency was not only influenced by CMC and γ but also wettability. |
