The average shelf life of fragrance oil is about one year. It is dependent on time, temperature, and exposure to air and light. For best results, we suggest purchasing only enough fragrance that you will use within 6 months to a year.
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 spoil more quickly. We recommend that you store fragrance oils in a cool dark place away from light and heat. In case you need to let the oils sit for over one year, we recommend testing each fragrance in a candle before making a large batch.
