The parameters of sensory analysis were color, unburnt candle scent, burnt candle scent and overall acceptability. The data from sensory analysis is processed statistically, then proceed with the Duncan Multiple Range Test (DMRT) if the significance value is less than 0.05. The results showed that volatile compounds found in cinnamon essential oil were 42.09% for (Z)-3-Phenylacrylaldehyde, 2-Propenal, 3-phenyl-Cinnamaldehyde, 24.33% for 4H-Thiopyran, and 13.14% for Propylene Glycol. The best formulation of cinnamon aromatherapy scented candle is A4, in the parameters of unburnt candle scent, burnt candle scent, and overall acceptability get the highest point of 6.47, 6.07 and 6.43 respectively.
