The Science of Scent Projection: Why Some Perfumes Vanish

Projection is a measurement of 'distance'—how far the molecules travel from your skin into the air around you. This is determined by the **Volatility** of the ingredients. Lighter molecules like citrus and mint have high volatility; they 'leap' off the skin instantly, creating a massive initial bubble. However, they also evaporate quickly. Heavier molecules like Sandalwood and Oud have low volatility; they stay close to the skin, projecting less but lasting much longer.

Many people think that a 'Parfum' (high oil concentration) will project further than an 'Eau de Toilette' (lower oil, higher alcohol). The opposite is often true. Alcohol is the 'engine' of projection; it helps the fragrance molecules lift off the skin and reach the noses of people across the room. A high-oil Parfum might last 12 hours but only be detectable to someone hugging you, while an EDT might only last 4 hours but fill a hallway. Understanding this 'Push and Pull' is key to choosing a scent for specific occasions.

We show you how to use our 10ml travel atomizers to 'top up' specific note layers throughout the day, giving you control over both your projection and your longevity. Whether you want to fill a boardroom or keep your scent intimate for a date, the science of volatility is your best tool. [Master the science of projection](https://essentia-perfume.com).
