Produção de sabão em pasta perfumado a partir de óleo descartado (fritura)

Abstract

This work aims to present a study on the reuse of discarded frying oil for the production of scented and colored paste soap. The growing concern with environmental preservation and the need for proper disposal of cooking oil waste motivated this project. The methodology involved the collection of used frying oil, followed by a filtration process to remove impurities. Subsequently, the oil was subjected to saponification with potassium hydroxide at different concentrations (40%, 45%, 50%), resulting in the formation of soap. To give the final product distinctive characteristics, dye and essence were added. The results showed that the produced soap had good consistency, effective cleaning power and a pleasant fragrance, in addition to contributing to the reduction of the environmental impact caused by the improper disposal of cooking oil. It is concluded that the reuse of frying oil for the manufacture of paste soap is a viable and sustainable alternative, promoting environmental and economic benefits.
