An aqueous solution of a commercial liquid synthetic detergent (1 vol%) for kitchen use was photodecomposed in the presence of TiO2 powder under an atmosphere of air at room temperature. The concentration of the detergent decreased to about one-half of its initial value at illumination times of 6 h. The yield of gaseous products decreased in the order of CO2>C2H4>H2. Illumination for 6 h decreased the concentration of oxygen to about one-third of the initial value.
