Extraction Methods of Rosa Rubiginosa

Historically, the aromatic and medicinal components of Rosa rubiginosa, commonly known as sweetbriar or rosehip, were obtained through traditional solvent extraction and maceration. For centuries, petals were soaked in solvents like hexane or alcohol to draw out essential oils, while the nutrient-rich seeds were often processed into syrups or tinctures using water and sugar-saturation methods to preserve their therapeutic properties for medicinal use.

Modern extraction primarily utilizes cold pressing and supercritical carbon dioxide (CO2) extraction. Cold pressing is favored for rosehip seed oil as it preserves high levels of tretinoin and essential fatty acids without the use of heat. Supercritical CO2 extraction represents the latest advancement, using pressurized carbon dioxide to isolate bioactive compounds like carotenoids and tocopherols. This solvent-free method is considered the gold standard for purity and stability, capturing a full spectrum of volatile and lipid fractions while ensuring no chemical residues remain in the final extract.

Rosa Rubiginosa, often cherished for its "sweetbriar" quality that merges classic rose with a distinctive green apple freshness, is a favorite in modern compositions seeking a naturalistic and slightly fruity floral lift. While many classical rose fragrances rely on heavy, lush blooms, this note offers a contemporary, airy elegance. It is notably featured in fragrances such as **Rosé O Boticário** (2020) and **Alatau Wings** by Faberlic (2024), where its bright, crisp character is used to create invigorating and feminine bouquets.

The versatility of Rosa Rubiginosa allows it to cross gender boundaries, offering a sophisticated twist on the traditional rose. Its tart, refreshing undertones are particularly appealing in unisex and niche releases. An example of its complex deployment can be seen in **Rosa Autumnalis** by Rosae Virtus (2023), which leverages the note's naturalistic freshness to blend seamlessly with deeper aromatic elements, providing a balanced, seasonal scent profile that avoids excessive sweetness.

Beyond modern and niche uses, Rosa Rubiginosa is also utilized to add an unconventional layer to established fragrance families. In creations like **Ballerina No 2** by Les Parfums de Rosine (2015), the sweetbriar quality complements the central rose theme by introducing a sparkling, youthful vitality. Other examples of its application include **Zodiac Terra** (Faberlic, 2025) and the earlier scent **Cherry Mousse** (Avon, 2013), demonstrating its appeal in compositions ranging from sophisticated floral blends to light, fruity-gourmand interpretations.

Seasonality of Rosa rubiginosa

• Blooming typically occurs from late spring to early summer, generally between May and July, when the plant produces vibrant pink flowers
• Aromatic young foliage emerges in the spring, releasing its signature apple-like scent most strongly after rain or when brushed
• Fruit ripening begins in late summer, with bright red or orange-red hips maturing in the autumn, usually between August and October
• Ornamental interest continues into the winter as the durable hips persist on the branches, providing a crucial food source for birds during the colder months
• Dormancy takes place during the late fall and winter seasons, with the shrub losing its deciduous leaves before new growth restarts in the spring
