Have you ever spent £200 on a designer perfume, sprayed it on before work, and realized by lunchtime that the scent has completely vanished?

It is frustrating. You pay for luxury, but you are mostly paying for alcohol.

At Oud Aruma, we get asked this question every day: "Why does my fragrance fade so fast?" The answer lies in simple chemistry—and it is exactly why perfume oils are the secret weapon of fragrance lovers.

Here is the science behind why oils last longer than sprays, and why you might want to make the switch.

1. The Alcohol Factor: Evaporation vs. Absorption

The biggest difference between a standard Spray (Eau de Parfum) and a Perfume Oil is the base.

• Sprays are typically 80-90% alcohol. Alcohol is volatile, meaning it is designed to evaporate quickly. When you spray it, the alcohol explodes into the air, carrying the scent with it. This gives you a huge "cloud" of scent immediately, but because the carrier evaporates, the scent fades with it.

• Perfume Oils contain 0% alcohol. They use a carrier oil (like Jojoba or DPG) which does not evaporate. Instead of flying off your skin, the oil sinks into your skin. This "locks" the scent molecules down, allowing them to release slowly over 8-12 hours.

Think of it like this: A spray is like a firework—loud and bright but over quickly. An oil is like a slow-burning candle—steady, warm, and long-lasting.

2. Concentration is King

When you buy a bottle of designer spray, you are often buying a lot of filler.

• Eau de Toilette: 5-10% actual perfume.

• Eau de Parfum: 15-20% actual perfume.

• Perfume Oils: Often 100% concentrated.

Because oils are undiluted, you only need a tiny drop to achieve what 5-6 sprays would do. A 10ml bottle of our [Oud Wood Inspired Oil](insert link to product) can often last as long as a 100ml bottle of designer spray.

3. The "Scent Bubble" Effect

Have you ever been choked by someone’s perfume in an elevator? That is the "projection" of alcohol sprays.

Perfume Oils behave differently. They sit closer to the skin. They create an intimate "Scent Bubble" around you. People won't smell you from across the street, but when they step into your personal space (or give you a hug), they will get a rich, deep hit of fragrance.

This makes oils perfect for the office, dates, or anywhere you want to smell incredible without overpowering the room.

4. Better for Your Skin

Alcohol is a drying agent. If you have sensitive skin, spraying high-alcohol perfumes on your neck or wrists can cause irritation or dryness.

Our oils are moisturizing. They nourish the skin while scenting it, making them safe for sensitive skin types.

The Verdict?

If you want a loud blast of scent for a quick event, sprays are great. But if you want a rich, complex scent that stays with you from your morning coffee until you go to bed, Oud Aruma Perfume Oils are the upgrade you need.
