Produção de sabão em pasta a partir de óleo de soja reciclado ( Fritura)

Abstract

This work demonstrates the issue generated by the improper disposal of residual frying oil, a substance with the potential to harm the environment in various ways, being one of the challenges for establishing sustainable development. In this sense, there are several solutions that can be presented to address this diversity, with the reuse of oil being one of the most recommended. For example, we have the use of RFO as a reagent for the production of paste soap, and this realization was the main objective of this study. Initially, the oil underwent two deodorization techniques to analyze its suitability for the process, which ultimately concluded that treatment with sodium hypochlorite was the most compatible with the initial proposal. Subsequently, with the deodorized oil, paste soap was made by mixing it with a potassium hydroxide solution at different concentrations (44, 46, 48, and 50%), obtaining, from solutions of 46 to 50%, a product with characteristics that were understood as satisfactory for product characterization as quality, considering that pH, emulsifying power, and emulsion power confirmed this fact. In this sense, the reuse of RFO for paste soap production stands out as an efficient alternative to significantly reduce environmental impact, contributing to a balanced environment in which any citizen can participate in this process, as it is a relatively simple process that can be adapted for domestic use.
