Fragrance oils are concentrated oils that are used to add scent to a variety of products, including perfumes, candles, soaps, and lotions. They are typically made from a blend of synthetic or natural ingredients, including essential oils, and are designed to mimic the scent of natural materials such as flowers, fruits, and spices. Fragrance oils are a cost-effective alternative to essential oils, as they are less expensive and often have a stronger and longer-lasting scent. They come in a wide variety of scents, ranging from sweet and fruity to spicy and musky, and can be used to create a unique and personalized scent for any product.
