ROSA GALLICA FLOWER OIL.

Questionable CAS 84604-13-7 / FRAGRANCE, SKIN CONDITIONING - EMOLLIENT

Rosa Gallica Flower Oil, derived from the French Rose, functions primarily as a fragrant emollient and skin-conditioning agent. While robust antioxidant and anti-inflammatory properties are observed in its extracts, the oil itself is recognized as an established contact allergen, necessitating cautious formulation.

Science

Mechanism of Action

Rosa gallica flower oil and its extracts exert antioxidant properties through free radical neutralization and demonstrate anti-inflammatory effects by moderating redness and irritation. Its primary component, gallic acid, has been shown to downregulate UVB-induced COX-2 and MMP-1 expression and modulate the c-Raf/MEK/ERK/c-Fos signaling axis, contributing to collagen preservation. Furthermore, it delivers hydration and moisturization via essential fatty acids, vitamins, and minerals, which can also aid in skin brightening and provide soothing benefits.

Key findings

  1. 01 Rose petal extract at 100 µg/ml demonstrated over 90% ABTS radical scavenging activity, comparable to 10 µg/ml vitamin C. It also reduced sUV-induced COX-2 expression, attenuated cytokine expressions, and modulated key signaling pathways (MKK4-JNK, MEK-ERK, MKK3-p38).
  2. 02 Aqueous R. gallica extract, with IC50 values of 20.0 µg/mL (ABTS) and 39.0 µg/mL (DPPH), exhibited dose-dependent radical scavenging. In-vivo studies indicated pronounced analgesic (124%) and anti-inflammatory (67.58%) effects.
  3. 03 Rosa gallica oil alone showed a low but statistically significant cytotoxic effect on lymphocyte cells (without dose-dependence) at concentrations ranging from 50-500 µg/ml.

Transparency

Dusting Analysis

Not commonly dusted

The majority of robust clinical efficacy data, particularly regarding antioxidant and anti-inflammatory benefits, stems from studies on Rosa gallica extracts rather than the flower oil itself. Furthermore, one study indicated a cytotoxic effect of the oil at concentrations between 50-500 µg/ml on lymphocyte cells. Considering the oil's established contact allergen status, its inclusion should prioritize safety and formulation stability over speculative active concentrations.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

The Cosmetic Ingredient Review (CIR) has not specifically evaluated Rosa gallica flower oil. However, the Scientific Committee on Consumer Safety (SCCS) identifies Rosa gallica flower oil as an established contact allergen in humans. While the European Union recognizes Rosa Gallica extract as safe, it advises moderate doses and caution for individuals with sensitivities. The oil naturally contains known cosmetic allergens such as Citronellol, Eugenol, Geraniol, Limonene, and Linalool. Avoidance on broken or irritated skin is crucial.

Our Assessment

Verdict

Questionable

While offering emollient and aromatic properties, Rosa Gallica Flower Oil is an established contact allergen with limited direct efficacy data for active skincare benefits, making its inclusion questionable for precision formulations, particularly for sensitive skin.
