The best quality and highly sought rose oil is obtained from the cultivated in Bulgaria Rosa damascena – the Kazanlak oil-bearing rose grown in the Rose Valley where it has found the most appropriate conditions for its growth and yields the highest quality oil.
The rose oil is a natural product derived by water-steam distillation of fresh blossoms from the oil-bearing rose - Rosa damascena Mill, cultivated in the Rose Valley, where it has found the most suitable conditions for its growth. One kilogram of rose oil is usually produced from 3 to 3,5 tons of rose blossoms. About 283 components are found in the composition of the Bulgarian rose oil. They are divided into two types of substances: carriers and fixatives of scent. The carriers of scent are the liquid part of the oil – elaeoptene. The fixatives of scent are solid at room temperature and odorless but they fix the scent and make it durable – stearoptene. Out of the numerous components of the elaeoptene the ones with rose scent are citronellol, geraniol, nerol, phenyl ethyl alcohol, but the typical rose odour is formed by the presence of microelements.
The Bulgarian rose oil is accepted as a world standard of quality. It is widely used in perfumery, cosmetics and medicine.
