If you’ve ever had a customer say your perfume fades within an hour or two, don’t immediately blame the fragrance oil. The issue is often something missing from the formulation: a fixative. Understanding what fixatives do — and why they matter — is one of the most practical upgrades you can make to your dupe perfume formula.
A fixative is an ingredient added to a perfume formulation to anchor the fragrance and slow down the rate at which it evaporates from skin. Without one, even a high-quality fragrance oil can feel short-lived — the scent lifts quickly and doesn’t stay close to the skin long enough to make an impression.
Think of it this way: fragrance oil carries the scent, alcohol delivers it, and the fixative holds it in place. Each component plays a different role. Leaving out the fixative is like building a house without a foundation — everything else may be in order, but it won’t last.
Fragrance molecules evaporate at different rates. Top notes — the bright, light opening accords — are highly volatile and disappear quickly. Base notes are heavier and linger longer. Fixatives work by binding to the fragrance molecules, particularly the lighter ones, and reducing their rate of evaporation. The result is a more even, sustained release of scent throughout the wear.
A good fixative also improves sillage — the trail or projection of a fragrance as you move. This is one of the qualities customers notice and talk about. A perfume with good sillage feels luxurious and present. One without it can feel thin, even if the scent itself is excellent.
Designer perfumes are professionally formulated with fixative compounds already built into the composition. When customers compare your dupe to the original, longevity and sillage are two of the first things they notice. A dupe that smells accurate but fades in two hours will always feel like an inferior product — even if the fragrance oil itself is high quality.
Adding a fixative to your formulation bridges that gap. It brings your dupe’s performance closer to the original in the areas customers care most about.
A common mistake is trying to solve longevity problems by increasing the fragrance oil concentration. This helps to a point, but it has limits — and at higher concentrations, the scent can become overpowering or cause skin sensitisation. A fixative solves the longevity problem more elegantly, allowing you to maintain a balanced oil-to-alcohol ratio while still achieving lasting performance.
Not all fixatives perform equally. For dupe perfume formulation, look for one that:
FIXXIT is Scentella’s own fixative, developed specifically for perfume formulation. It is a standalone product — separate from our fragrance oils — which means you can choose to incorporate it into your formula at the concentration that works best for your finished product.
If you’re currently selling dupe perfumes and haven’t added a fixative to your formulation, FIXXIT is worth exploring. The difference in longevity and projection is noticeable — and so is the difference in customer feedback.

Do I need a fixative if I’m already using a high oil concentration?
Higher oil concentration helps with intensity, but it doesn’t solve longevity in the same way a fixative does. A fixative slows evaporation at the molecular level — increasing oil concentration just means more molecules to evaporate at the same rate. The two work differently and ideally complement each other.
Will a fixative change the scent of my perfume?
A quality, low-odour fixative should not noticeably alter your fragrance profile. In fact, many perfumers find that a good fixative enhances the overall character of the scent by allowing the base notes to come through more fully.
At what stage do I add the fixative to my formula?
This depends on the specific fixative you’re using. For FIXXIT, contact us directly for usage guidelines — we’ll advise on the recommended concentration and mixing method for your formulation.
Is a fixative the same as a base note?
No. Base notes are fragrance ingredients that happen to be heavy and slow-evaporating — they contribute to the scent profile. A fixative is a functional ingredient that anchors all the other notes, including the lighter ones. They serve different purposes in a formula.
