Neroli

Orange blossom can be described as smelling sweeter, warmer and more floral than neroli.

[1] By the end of the 17th century, Anne Marie Orsini, duchess of Bracciano and princess of Nerola, Italy, introduced the essence of bitter orange tree as a fashionable fragrance by using it to perfume her gloves and her bath.

[2] Like many raw materials, neroli can cause sensitisation[3] due to a high content of aromatic terpenes; e.g., linalool, limonene, farnesol, geraniol and citral.

Neroli oil is reportedly one of the ingredients in the closely guarded secret recipe for the Coca-Cola soft drink.

[4] It is a flavoring ingredient of open source cola recipes,[5] although some variants consider it as optional, owing to the high cost.
