ROSA ODORATA EXTRACT.

Valuable CAS 97676-09-0 / ASTRINGENT, HUMECTANT

Rosa Odorata Extract is a botanical ingredient characterized by its rich profile of volatile compounds, including monoterpene alcohols. It offers multifaceted skin benefits, primarily acting as an antioxidant and anti-inflammatory agent while providing gentle hydration and mild astringent properties.

Summary

Antioxidant Anti-inflammatory Hydrating Astringent Soothing Fragrance Component

Science

Mechanism of Action

Rosa Odorata Extract comprises key volatile compounds such as 2-phenylethanol (8.4–33.9%), geraniol (12.8–32.5%), and a combination of citronellol + nerol (17.7–26.5%). These components contribute to its antioxidant and anti-inflammatory effects, effectively soothing skin irritation and reducing redness. The extract delivers gentle hydration and possesses mild astringent qualities, which can assist in skin purification and blemish prevention, particularly beneficial for oily and acne-prone complexions. Additionally, rose extracts may activate specific olfactory receptors (OR10A6, OR2AG2, OR11H4) in the skin, potentially offering protection against stress-induced skin alterations, such as the appearance of under-eye dark circles. The presence of phenolic compounds, including anthocyanins, further enhances its antioxidant capacity.

Stability

The optimal pH range for Rosa Odorata Extract stability is not precisely defined. However, depending on the extraction methodology, rose extracts can yield both aqueous (hydrophilic) and oily components, indicating solubility across different phases.

Conflicts

  • When formulating with retinoids, caution is advised as certain rose extracts (e.g., Rosa Canina) are noted to contain vitamin A, which could impact cumulative retinoid exposure.
  • Potential for sensitization or irritation exists due to the natural presence of fragrance components, specifically citronellol and geraniol, within Rosa Odorata Extract.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

Rosa Odorata Extract itself has not undergone specific review by the Cosmetic Ingredient Review (CIR) Expert Panel. However, other Rosa species-derived ingredients are generally considered safe for cosmetic use under current practices. The U.S. FDA recognizes essential oils and extracts of various rose species as Generally Recognized As Safe (GRAS) for food consumption. Notably, Rosa Odorata Extract contains geraniol (12.8–32.5%) and citronellol (17.7–26.5% when combined with nerol) as volatile components. These are recognized fragrance allergens under Annex III of the EU Cosmetics Regulation, necessitating labeling if concentrations exceed 0.001% in leave-on products or 0.01% in rinse-off products. Formulators should employ good manufacturing practices to minimize impurities and address potential allergenicity.
