Mainly produced in Egypt, India, Morocco. The names 'Royal jasmine' and 'Spanish jasmine' reflect traditional usage.
Family Oleaceae. Same family as olive and lilac. Flowers picked by hand just before dawn when scent concentration peaks.
Jasmine absolute is frequently adulterated with indole, α-amyl cinnamic aldehyde (a low-to-moderate allergen), ylang-ylang fractions, synthetic jasmine bases, synthetic jasmones.
Coniferyl benzoate, a potent skin allergen, may be present because Sumatra benzoin is sometimes added to jasmine concrete as an adulterant.
