Fragrances may be invisible when worn, but they have a lot of sway when it comes to how others view you. No pressure, then. Aside from how the juice smells – which is dictated by its ingredients, also known as ‘notes’, in the trade – finding the correct concentration is essential. Too light, and it'll be gone before you’re out the door. Too intense, and it can leave everyone within a mile radius feeling like they just huffed glue.
To ensure you hit the sweet (smelling) spot in-between, ahead is a brief explainer about the difference between two of the most common concentrations: cologne and eau de toilette. Tell your fellow commuters they can thank us later.
What is cologne?
Eau de cologne (or simply "cologne") is one of the oldest forms of perfume in the Western world, dating back as far as the 14th century. Though today the term is often misused to describe any masculine scent, it refers specifically to a low-concentration fragrance containing just 2-4% oils, diluted predominantly with alcohol.
That doesn't mean colognes aren't worth a sniff, though. They are typically created using citrus and herbal notes, including bergamot, grapefruit, lavender and neroli, making them brilliantly bright, fresh and incredibly easy to wear.
What is eau de toilette?
Despite translating literally to "toilet water", a well-picked eau de toilette is anything but a stinker. One of the most popular and accessible forms of fragrance, they typically contain a 10% oil concentration, placing eau de toilette somewhere between eau de cologne and eau de parfum both in terms of strength and price.
Fresh top notes such as citrus are usually given centre stage, with richer ingredients like cedarwood and amber brought in at the base as a supporting act.
Cologne vs eau de toilette: what's the difference?
Attempting to memorise the difference between cologne and eau de toilette (and aftershave and cologne, and cologne and perfume) is enough to give you a headache before you even start sniffing scents.
"The main difference is the concentration and therefore the lasting power," explains Alex Goddard, training manager at Italian fragrance house Acqua di Parma. "A traditional eau de cologne will usually last up to two hours and an eau de toilette up to four hours."
That said, Goddard doesn't suggest putting too much emphasis on the words on the bottle. "Different fragrance strengths are associated with different types of raw material, and different types of raw material typically have different lasting powers."
In a nutshell, what smells you like will ultimately dictate which one you go for and how long your fragrance will last. Just remember to adjust how much you apply, and how often, to the strength of your fragrance.
