Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically evaluated Rose Ketone-5; however, they have reviewed related natural Rosa damascena-derived ingredients. This synthetic compound is generally considered safe for use in cosmetics and personal care products when used at appropriate, restricted concentrations. Due to its inclusion in the damascone group of chemicals, regulatory bodies like the EU (CosIng Annex III) and New Zealand restrict its cumulative use to a maximum concentration of 0.02% in finished cosmetic products to address skin sensitisation concerns. The International Fragrance Association (IFRA) also sets category-specific limits, such as 0.046% for face creams (Category 3) and 0.084% for body lotions (Category 9). Individuals with known fragrance sensitivities or allergies should perform a patch test.
