STUDY THE EFFECT OF HAIR STYLE PRODUCTS ON THE QUALITY OF DOMESTIC WASTEWATER- WAX AS CASE STUDY

Abstract

People have used personal care products throughout history. Hair cosmetics are among the most common and widely used products. In this study, the effect of WAX and shampoo, which are hair cosmetics, on domestic wastewater pollution were investigated separately and together. The study consists of two stages. In the first stage, Chemical Oxygen Demand (COD) and hydrogen concentration (pH) of WAX, shampoo and WAX + shampoo were analyzed. COD results were 1096 mg / L, 584 mg / L and 1896 mg / L, respectively. In the second stage, these products (0.1 g WAX and 0.1 g shampoo) were added separately and jointly to 2g of human raw hair. In this stage, wastewater was prepared by shaking sample of hair in 100 mL water for 30 minutes. The concentrations of COD were 1296 mg / L, 592 mg / L and 1328 mg / L, respectively. The PH increased from 7.3 to about 8 after adding cosmetics. The experiments showed that the added WAX to the hair is reduced by 40% by weight in 250C and 30 minutes. In order to quantify and realize the human habits of using such hair cosmetics during the day, a questionnaire was prepared and distributed to 385 of people. It was found that 43% of the people used WAX and 45% of them used this product every day. Accordingly, this study have been investigated only WAX and shampoo, keeping in mind that chemicals used for cosmetic purposes have been found enormous effects on domestic wastewater.
