A. Background of the Study Today, candles are made not only for lighting purposes but for many other uses such as home décor, novelty collections, as fixtures for big occasions (weddings, baptismals, etc.), and as scented varieties for aromatherapy. Candles are made from different types of waxes and oils.
Cooking oil is a major kitchen item in Filipino households. It is also used substantially in fast-food outlets, where it is used in different stages of food preparations. Ordinarily, used cooking oil is discarded. This waste oil pollutes and clogs canals and sewerage systems
.
In our country today more ways are now made to utilize common things in order to make products easier and cheaper. In this research study, used cooking oil is used as an alternative for paraffin wax in candle making
.
In the field of Science, this study contributes a lot for the reason that we can find alternative for paraffin wax as main component in candle making, besides paraffin was derived from petroleum and the later is much expensive. This study contributes knowledge to the researchers and also to the community in the sense of finding an alternative way to utilize used cooking oil that may pollute and clog canals and sewerage systems if not recycled in essential ways, instead of chemically synthesized sources. It also improves the human condition physically through minimizing the waste oil that pollutes our country.
B. Statement of the Problem
The study aims to produce a low-priced, high-quality candle by using used cooking oil as a major component. The following candle compositions were used: 100 percent paraffin wax; 90 percent paraffin and 10 percent oil; 80 percent paraffin and 20 percent oil; 70 percent paraffin and 30 percent oil; 60 percent paraffin and 40 percent oil; 50 percent paraffin and 50 percent oil. The firmness, texture, and light intensity of the candles were tested and compared.
Results of the tests showed that the candle made
