This work is part of the context of wastewater management in developing countries. The objective is to set up a simple and less expensive treatment process for soap and cosmetic wastewater. The wastewater from a soap and cosmetics industry in the Abidjan-sud zone was studied. The chemical oxidation method using potassium permanganate is used for the degradation of this raw wastewater at room temperature and basic pH. Indirect volumetric dosage by manganometry and the linear regression method are used to determine the overall order and kinetic parameters of the degradation reaction of oxidizable materials in the wastewater. It appears from this study that permanganate oxidizes the wastewater from the soap and cosmetics unit. All of the materials oxidizable by potassium permanganate (MOPP) with a normality of 2.5.10^-3 degrade after approximately 90 minutes. This MOPP degradation reaction follows kinetics of order 1 with a correlation coefficient. MOPPs behave like a single species and are essentially made up of organic pollutants. The oxidation reaction of MOPP by at room temperature and basic pH is slow with an apparent rate constant
