Perfume Composition
The base below every perfume is the skin of the wearer.
The base of a perfume is what stays the longest and is designed to enhance the scent of the skin.
Natural base materials range from simple, sweet vanilla-scented Benzoin and slightly spicier Balsam Peru over herbal spicy Angelica Root (some people say it smells like instant noodles), grass-rooty and in some cases smoky Vetiver, mossy-sweet Oakmoss to warm, leathery Labdanum (some don't like it, I love it).
The heart of a perfume is formed by materials that match well with the base. The most classic, fitting with everything, is rose. But all other floral materials and spices like cinnamon and clove can be part of a base.
The top of a perfume is the first to evaporate and only there for the first impression. The most used is Bergamot, but other Citrus fruits like Grapefruit, Lemon, Lime, Mandarin, Orange and Tangerine also make good top notes.
There are plenty more aromatic materials that can be used in a perfume, but one that I like to avoid is alcohol. I don't understand how the modern shift to alcohol as a carrier happened, but I neither like its smell nor its effect on the body.
Instead, I prefer to use the much less volatile Jojoba oil, and instead of a spray bottle fill it into a roll-on bottle. Or, even less volatile, use a combination of Jojoba oil and beeswax as a carrier.
