- Is the pyramid structure indicating the strength of the top, middle, and base notes accurate?
This is just a concept for reference. Upon spraying, all notes will appear at the same time. However, the ingredient volume and molecular weights are all different. The top notes, which have the lightest molecular weight, will reach our noses first; hence we will detect the top notes at the first instance. Yet at the same time, they will also contain some minor traces of the middle and base notes. After the lightest molecular ingredients have dispersed, the heavier molecular ingredients, which consist of the middle and base notes, will become more prominent at this stage. Similarly, when the middle notes have dispersed, the base notes are what remain. The stages of this happening in each fragrance are different as they depend on the formula and ingredient make up.
- Does a perfume made from all natural ingredients mean it is of a better quality, more valuable, and safer to use?
Not necessarily. There are many natural ingredients that can cause allergy or poisonous reactions. For example, one of the common ingredients in fragrances, such as natural citrus essential oil, can cause phototoxic reaction due to some natural compounds that are found in this substance. Therefore, using synthetic ingredients are generally safer as they only copy the scent’s molecular composition and have eliminated compounds that may cause allergic reactions as they are specifically for fragrance making purposes. Also, many natural ingredients are agricultural products and will depend on the year’s seasonal weather for harvest quality and quantities, which in turn become unstable for quality assurance.
- What are these impurities that are found in some of my fragrances after some time on the shelf?
Some ingredients will cause some impurities after aging on the shelves. Similar to aged wine, this is a normal process. As our fragrances are distilled twice before packaging into our bottles, the majority of the impurities are filtered out during this process, but there will still be traces that remain. It is still safe to use.
- Is Eau de Parfum’s intensity the most long lasting and the most intense fragrance?
Eau de Parfum, Eau de Toilette, and Eau de Cologne are only defined terms for a fragrance’s standard of scent concentration. However, the long lasting effects are not directly related to the concentration of scent. Instead, how long a fragrance can last on a user actually depends on the fragrance formula’s ingredient quantity and molecular mark up.
