However,repparttar 149048 other component of soap,repparttar 149049 hydrophilic component, will be left onrepparttar 149050 surface. When water is applied onto this surface with a sponge,repparttar 149051 hydrophilic component will be attracted torepparttar 149052 water molecules and is lifted fromrepparttar 149053 surface, together withrepparttar 149054 oil.
