The Chemistry of Captivating Fragrances

The Fragrance Beyond Paradise: A Split Creation

Picture this: the intoxicating scent of a fragrance that takes you beyond paradise. It’s called Beyond Paradise, and it can be found in stores across the nation. But what if I told you that this fragrance has been carefully split into parts by Estée Lauder and the talented perfumer, Calice Becker? I am incredibly grateful to them for this remarkable creation.

Let’s delve into the intricacies of this fragrance. It has been divided into successive bits and chords, starting with the top note that you’re currently experiencing. Soon, you’ll encounter what they call the lush heart note, a captivating element that adds depth and richness to the scent.

The top note, known as the Edentop note, draws inspiration from the breathtaking Eden Project in the U.K. It exudes a refreshing aroma, reminiscent of freshly cut grass. Interestingly, the lush heart note contains no Melaleucabark, despite its name, as it is entirely forbidden. These elements combine to form the complete fragrance that envelopes you.

Now, here’s something fascinating: the scent you’re smelling consists of several hundred molecules suspended in the air. When I inquired about the exact number of molecules, nobody would disclose it. So, I decided to analyze it using a Gas Chromatograph in my office. To my surprise, there were approximately 400 molecules present. This dispels the notion that scent is subjective. In fact, we all perceive the fragrance quite similarly.

Smell often carries the reputation of being subjective, varying from person to person. However, perfumery demonstrates that it cannot be entirely true, as it would undermine the artistry behind it. Smell, just like taste or sight, has its own objective qualities, and perfumery reveals this truth.

Now, as you continue to inhale the enchanting aroma, let me take you on a journey through the history of an idea. Everything that creates the scents we smell is composed of atoms from what I like to call the “Upper East Side” of the periodic table. It’s a safe and pleasant neighborhood you don’t want to leave if you wish to pursue a career in perfumery.

Some people, back in the 1920s, attempted to incorporate elements from the less desirable parts of the periodic table, but their efforts proved unsuccessful. The five atoms I’m referring to form the foundation of nearly every scent we encounter in real life, from the aroma of coffee to fragrances we wear.

Now, let’s focus on the top note you experienced at the beginning—reminiscent of the fresh scent of cut grass. In the language of perfumery, it is known as cis-3-hexene-1-ol. This molecule consists of six carbon atoms, hence the “hexa” part, and features a double bond and an alcohol group, represented by “ol.” Its name, cis-3-hexene-1-ol, might impress your friends at parties.

To truly understand why cis-3-hexene-1-ol smells like cut grass, we need to consider its molecular structure. If you visualize the molecule’s skeleton, you can dress it up with additional atoms, such as hydrogen. However, it’s important to note that the atoms have a certain sphere or region that repels other molecules. This unique arrangement plays a role in determining the scent.

The prevalent theory behind scents is that shape dictates our perception of smell. It seems reasonable, given that shape governs numerous biological processes. Enzymes, antibodies, and even smell rely on the interaction between proteins and molecules. However, this theory has its flaws, and I’ll explain why.

There is another theory that suggests we perceive molecular vibrations
