The Science of Perfume Longevity — How Fixatives Work

One of the most common questions perfume lovers ask is, “Why does this fragrance last all day while another fades in just a few hours?” The answer often lies in a key ingredient category: fixatives. These unsung heroes of perfumery help lock in scent molecules, slowing down evaporation and keeping your perfume’s aroma alive for longer.

In this guide, we’ll break down what fixatives are, the science behind how they work, and why they matter for your fragrance experience — especially in Singapore’s warm, humid climate.

What Are Perfume Fixatives?

Fixatives are substances added to perfume formulas to stabilise volatile aroma compounds and extend the life of a fragrance on your skin. They work by slowing down the evaporation of lighter top and middle notes, allowing the scent to remain balanced over time.

Types of Fixatives

1. Natural Fixatives

Derived from botanical or animal sources, natural fixatives have been used for centuries:

• Resins: Benzoin, myrrh, frankincense add warmth and sweetness while slowing evaporation.
• Woods: Sandalwood, cedarwood act as both scent notes and fixatives.
• Animal Products: Historically, ambergris and musk were used, though most brands now use ethical synthetics.

2. Synthetic Fixatives

Modern perfumery often relies on synthetic molecules for consistency and ethical reasons:

• Ambroxan: A woody-amber note known for incredible longevity.
• Iso E Super: Adds a velvety, diffusive quality to scents.
• Galaxolide: A clean musk that lingers for hours.

How Fixatives Work

Perfumes are made up of volatile molecules that evaporate at different rates. Fixatives bond lightly with these molecules or form a base layer that slows their release. This helps ensure the scent doesn’t disappear too quickly, especially in hot and humid weather where evaporation happens faster.

Fixatives and Singapore’s Climate

In Singapore, high temperatures and humidity can cause lighter perfumes to fade rapidly. Scents with strong fixatives — such as woody bases or musks — tend to perform better, offering longevity without needing constant reapplication.

How to Spot Long-Lasting Perfumes

• Check the base notes — woods, amber, musk often indicate strong fixatives.
• Look for Eau de Parfum or Parfum concentrations for higher fragrance oil content.
• Read reviews focusing on longevity and projection.

Tips to Boost Perfume Longevity

• Moisturise skin before spraying to help lock in scent.
• Apply to pulse points where warmth releases fragrance gradually.
• Layer with matching scented products for extra staying power.
