The average shelf life of fragrance oil is about one year. It is dependent on time, temperature, and exposure to air and light. Another variable is the shelf life of the raw materials used to make up the fragrance. If there are more natural ingredients in the formula, it can go bad more quickly. We recommend that you store fragrance oils in a cool dark place away from light and heat. We recommend testing each fragrance in a candle before making a large batch if you need to let the oils sit for over one year.
