Amounts of two kinds of nitrogen containing soils removed from naturally soiled cloth were estimated from peak height in elution curve of gel filtration using Sephadex G-100. The relation between amount of the removed soil and detergency efficiency evaluated by reflectance measurement was discussed. It was found that the amount of nitrogen containing soil can be equivocally related to the detergency efficiency independent of the kinds of surfactant and builder aqueous solutions used as washing solution. In conclusion it seems unnecessary to asume the specific interaction between proteins and anionic surfactants such as sodium alkyl benzene sulf onate with respect to the mechanism of removal of nitrogen containing soils.
