Thank you for your inquiry. When crafting a perfume fixative, it's essential to align it with the base notes for a harmonious blend. Each fixative should correspond to the base notes, enhancing and preserving the fragrance. It's important to note that the use of any of the aforementioned synthetic chemicals in perfume making will impart characteristics of a base note. Mixing them together without evaluating the base note may not yield the desired result. For optimal results, consider evaluating and understanding the base notes of your perfume before incorporating fixatives. If you have further questions or need guidance on specific fixatives matching your base notes, feel free to ask Hammad
