Often referred to as 'Rose Geranium Oil' this is one of the most important and most commonly used ingredients in perfumery. China is the world's largest producer with the main production in Yunnan Province. It is easy to grow in this region with some farms able to harvests 4 times a year if conditions are favourable. It is estimated production levels are around 80-110MT per annum with 20-30MT consumed internally, the balance exported. France and the USA are cited as the world's largest importers; however, it is assumed that France is the biggest consumer (for fine fragrance). Chinese geranium is rich in‘citronellol’, accounting for just over 40% of the oil. Despite it's higher prices in today's market it is still the most sought after quality because of this fact. Other origins like Egypt contain 25% less citronellol. |
