Rose Oxide (CAS 16409-43-1) is a synthetic aroma chemical that is often used in perfumery to impart a fresh, floral, and slightly green character reminiscent of rose petals. It is valued for its ability to enhance the complexity of floral accords and is commonly found in compositions that aim to evoke a sense of elegance and sophistication. In fragrance formulations, Rose Oxide typically occupies a middle to top note position, contributing to the overall bouquet of the scent while also providing a unique twist that can differentiate a fragrance from traditional rose oils. As a synthetic compound, it offers consistency and stability compared to natural rose extracts, which can vary in quality and scent profile. While Rose Oxide is generally considered safe for use in cosmetics and fragrances, it is important for formulators to be aware of any potential allergenic properties, as with many floral components. Regulatory guidelines, such as those from IFRA, may apply, and it is advisable to consult the latest safety data and usage restrictions when incorporating this ingredient into formulations. — AI-generated summary, 2026-09-02.
A sharp, sparkling floral note with a distinctly metallic-green edge — evokes crushed rose petals and geranium leaf with a cool, almost chilled facet. Diffusive and penetrating even at trace levels, giving rose accords a lifelike, dewy freshness.AI · claude-opus-4-7

Colorless mobile liquid.
Very slightly soluble in water, soluble in alcohol and oils.
Penetrating and very diffusive, gassy-green or “hard” green, floral odor of poor tenacity. The resemblance to Geranium appears only upon dilution of the Rose oxide, and best in a composition. The diluted material has also a Rose-like character. Certain materials have a less gassy, more “bread-like” topnote, which is warmer and more pleasant than the “gassy” type of odor. The odor of the laevo-isomer is sweeter, yet somewhat green. The odor of the dextro-isomer is more warm-spicy, sometimes gassy, more often just herbaceous.
