Fragrance oils are often highly concentrated and potent, and as such, they can cause skin irritation, redness, or allergic reactions if applied directly to the skin. Diluting fragrance oils is therefore essential to ensure their safe and controlled usage. The dilution of fragrance oils also moderates the intensity of the scent, making it more pleasant and suitable for various applications, such as perfumes, candles, and skincare items. Diluting oils also makes them easier to blend and allows for experimentation with new formulas without wasting materials. The most common method of diluting fragrance oils is by using carrier oils, which are usually derived from the fatty portion of a plant, such as nuts, seeds, kernels, or fruits. Carrier oils are unscented or lightly scented and help to dilute the fragrance oil without altering its original scent.
