The composition of perfume dupes is similar in basic structure to that of original perfumes, but often differs in the quality and origin of the raw materials used. A perfume generally consists of a fragrance concentrate, a carrier – usually ethanol or a similar alcohol – and sometimes additional fixative or stabilizing components. Dupes use more cost-effective alternatives to the often expensive essences of the originals, for example synthetic fragrance materials instead of natural raw materials. These synthetic alternatives make it possible to imitate the scent notes of the original, often with astonishing precision.
The pyramid structure of a fragrance, consisting of top, heart and base notes, is also present in dupes, although the nuances may be less deep or the transitions between the notes less harmonious.
The concentration of fragrance oils is also crucial: while high-quality original perfumes often have a high concentration of essences, dupes usually contain smaller amounts, which can affect the longevity and intensity of the scent. Despite these differences, many dupes offer a solid alternative, especially for everyday use, as they capture the essence of the original fragrance at a fraction of the cost.
