Perfume concentration, explained

Concentration describes how much fragrance concentrate is blended into the finished perfume. It is a useful formula detail, not a score for quality.

What the percentage means

A perfume at 20% concentrate by weight contains 20 grams of concentrate in every 100 grams of finished perfume. This is an example, not a claim that every Petals & Smoke scent uses 20%. By weight (w/w) and by volume (v/v) measure different things and are not interchangeable. We identify the basis alongside verified percentages.

When a product says "Target fragrance concentration," the percentage is the intended formulation loading, not an analytical assay of an individual finished batch.

More concentrated does not automatically mean better

Concentration can influence how a fragrance wears, but the materials and their proportions also matter. Some evaporate quickly; others remain noticeable much longer. Two perfumes with the same percentage can behave very differently.

Projection is how far a scent seems to radiate. Longevity is how long it remains perceptible. A scent can stay noticeable close up without filling a room. A percentage alone cannot promise either.

EDP, EDT and Extrait

These familiar names have no universally fixed concentration boundaries, and common industry ranges overlap. Different versions sharing a fragrance name can also use different compositions, rather than simply more or less alcohol. Experience each version on its own terms.

Choose the fragrance, not just the number

Read the scent notes and description, then notice the opening, how it develops and what remains later. Use concentration as one part of choosing a scent you enjoy wearing.
