Análise da qualidade de detergente produzido no laboratório da UTFPR no câmpus de Ponta Grossa

Abstract

The first version of detergents appeared in Germany after the 1st world war. Its advantage was its ability to clean even using hard water (with excess salts), which did not happen with soap. In the 1950s, there was an innovation in this field with the production of detergents derived directly from Aquil Benzene Sulfate. Aquil Benzene Sulfate is a low cost anionic detergent with high availability in the market. However, in the environmental requirement, its discharge generates pollution of water bodies. This is due to the fact that it has a branched chain of hydrocarbons, which aquatic bactéria cannot degrade, which causes its accumulation in surface waters. The quality of the detergent depends on several aspects that are related to its chemical composition and the function that each component performs. Given the above, this work aims at the production of detergent from a given formula and evaluation of its quality. For this, the values of pH, viscosity, turbidity, foam formation and stability were evaluated. The results obtained were compared with existing brands on the market.
