Rose is primarily composed of four dominant volatile aromatic compounds: citronellol, geraniol, nonadecane, and heneicosane. The monoterpene alcohols, citronellol and geraniol, are often associated with floral essential oils—geranium also contains rich concentrations—and they share more than a similar chemical makeup. There is good reason why Rose essential oil is valued so highly in personal care; both compounds are effective at supporting a healthy and clean appearance of the skin and hair. That cleansing power is also evident when used on surfaces. Nonadecane and heneicosane are a little more mysterious, and a lot less scientifically investigated, but based upon the breadth of research, they are a great example of essential oil synergy and exactly why Rose offers such profound benefits. Greater than the sum of its parts, an abundance of experimental and human clinical research has shown that Rose provides powerful benefits when used aromatically and topically.
