    (Research India Publications, 2016) Mtisi, Farlane; Parekh, Champaklal T.; Ochieng, Aoyi; Chiririwa, Haleden
    The study was carried out to investigate the most effective concentration of DEET and Permethrin in a mosquito repellent soap and to develop a method for the assaying of the active ingredients. The effect of perfume in a repellent soap was also investigated. In the study nine soaps were prepared and the concentrations of DEET and Permethrin were varied with six soaps having both ingredients. Efficacy tests were carried out on the different soaps. The most effective and economic soap in repelling mosquitoes was the one which had 50 % DEET. Physical and chemical tests revealed that the soaps had an average total fatty matter of 71.6 %, average moisture content of 14.35 % and average free alkali of 0.04.
