Abstract

Recently, non-ionic surfactants are widely used as home detergents. It is desired to develop a simple measurement method for evaluating the remaining non-ionic surfactants in the laundry, the effect of rinsing in the wash, and the behaviour of non-ionic surfactants in the drainage. In this study, a new quantitative determination method for evaluating the POE type of non-ionic surfactants is proposed. The method utilizes a handmade heating turbidimeter which measures the tubidity relating to its temperature change. The effectiveness of the proposed quantitative determination method is verified by comparing with conventional UV and ELISA methods.
