Generation of aromatic candles from different percentages of recycled edible oil

The purpose of this work is to use recycled oil in different proportions to make aromatic candles and carry out quality tests to select the best proportion. 3 batches of candles were made, mixing 60%-40%, 70%-30%; and 80%-20% from recycled oil and soy wax respectively. The evaluation consisted of 7 tests: Visual inspection, burning times, Candle Pond. Flame height, Sensory rating scale, Combustion afterglow check, Combustion and post combustion smoke. The results obtained show that the proportion of 70% recycled oil and 30% soy wax is the one that presents very similar characteristics to conventional candles, however, the use of other mixtures is not ruled out since depending on the characteristics. Whatever the client wants in a candle, such as a longer duration or lighting, the other proportions can be used.
