Rose otto is an essential oil extracted from the petals of the Damask rose (Rosa damascena) through steam distillation. It is one of the most expensive essential oils in the world, prized for its complex floral scent and its use in perfumery, skincare, and aromatherapy. The word “otto” (sometimes spelled “attar”) comes from the Arabic word for fragrance, and it distinguishes this steam-distilled oil from rose absolute, which is produced using chemical solvents.
How Rose Otto Is Made
Producing rose otto is a labor-intensive process. Roses are harvested by hand in the early morning hours, when the flowers still hold the most aromatic compounds. The fresh petals are then placed in large copper stills, where steam from a separate chamber passes over the plant material. As the steam moves through the petals, it pulls out the volatile oils. That oil-laden steam travels into a cooling chamber, where it condenses back into liquid. The essential oil naturally separates from the water and is collected.
The yield is extremely low. It takes roughly 3,000 to 5,000 kilograms of rose petals to produce a single kilogram of rose otto, which is a major reason for its high price. A small 5-milliliter bottle can cost anywhere from $50 to over $200 depending on purity and origin.
Where It Comes From
The two most important rose otto producing regions are Bulgaria’s Kazanlak Valley, often called the “Valley of Roses,” and the Isparta province of Turkey. Together, these regions supply the majority of the world’s rose otto. Bulgarian and Turkish rose oils share the same base species but differ slightly in their chemical makeup. Turkish rose oil tends to be somewhat higher in citronellol, one of the key aromatic compounds, which gives it a subtly different scent profile. Iranian and Indian producers also contribute to the global supply, with variations in aroma influenced by local soil, altitude, and climate.
What’s Inside Rose Otto
Rose otto is chemically complex, containing over 40 identified compounds. The three most prominent are geraniol, citronellol, and nerol, all of which are naturally occurring alcohols that contribute to the oil’s distinctive floral scent. Geraniol can make up anywhere from 0.2% to nearly 46% of the oil depending on growing conditions, while citronellol ranges from about 2% to 22% and nerol from 1.4% to 15%. The ratio between citronellol and geraniol is actually one of the main markers used to assess oil quality, typically falling between 3.3 and 6.9.
One distinctive physical trait of pure rose otto: it solidifies and forms waxy crystals at cool temperatures. If you refrigerate a bottle and see it turn semi-solid, that’s a sign of authenticity, not a defect. The oil returns to liquid as it warms back to room temperature. This crystallization happens because of naturally occurring wax-like compounds called stearoptenes that are present in steam-distilled rose oil. The International Organization for Standardization maintains a standard (ISO 9842, most recently updated in 2024) that defines the chemical benchmarks authentic rose otto should meet.
Skin and Aromatherapy Uses
Rose otto has a long history in traditional medicine, particularly in Persian healing traditions, where it was used for headaches, wound healing, muscle pain, and inflammatory conditions. Modern laboratory research supports some of these uses. The oil has demonstrated broad antibacterial and antifungal activity against several types of pathogens, including common molds and bacteria like Pseudomonas aeruginosa and Candida albicans. That said, most of this evidence comes from lab studies rather than large clinical trials, so the strength of the evidence varies by application.
In skincare, rose otto is valued for its ability to hydrate and soothe irritated or inflamed skin. It’s often recommended for mature or dehydrated skin, and its vitamins A and C content may help reduce the appearance of fine lines and age spots over time. Because it’s steam-distilled rather than solvent-extracted, it contains no chemical residues, which makes it a preferred choice for direct skin application (always diluted in a carrier oil).
In aromatherapy, the oil is primarily used for emotional support. It’s considered calming and is often diffused during periods of stress, grief, or hormonal fluctuation. The scent is gentler and more subtle than you might expect if you’re used to rose-scented candles or perfumes, which are typically formulated to be much stronger.
Rose Otto vs. Rose Absolute
These are the two main forms of rose oil, and the difference comes down to how they’re extracted. Rose otto uses steam. Rose absolute uses chemical solvents like hexane or ethanol, which dissolve the aromatic compounds from the petals before being evaporated off. The solvent method captures a broader range of scent molecules because the petals aren’t exposed to heat, so rose absolute tends to smell richer and closer to a fresh rose. Rose otto has a lighter, more delicate aroma.
The trade-off is purity. Because solvent extraction can leave trace chemical residues in the finished product, rose absolute is generally used in perfumery rather than therapeutic applications. Rose otto, being produced only with water and heat, is classified as a true essential oil and is the preferred form for aromatherapy and skincare use. In terms of therapeutic properties, both oils offer similar benefits for the skin and nervous system. The choice between them usually comes down to whether you prioritize a stronger scent (absolute) or a cleaner extraction method (otto).
How to Spot Adulterated Rose Otto
Because genuine rose otto is so expensive, adulteration is common. Cheaper oils are sometimes diluted with synthetic geraniol or citronellol, blended with palmarosa or geranium oil (which share some of the same chemical compounds), or mixed with carrier oils to stretch volume. A few practical signs of quality: the oil should crystallize when cooled, it should come with a gas chromatography report showing its chemical breakdown, and the price should reflect reality. If a full-sized bottle of “pure rose otto” costs $15, it almost certainly isn’t pure. Reputable suppliers will provide batch-specific testing data and reference the ISO 9842 standard.
