TETRAMETHYLBICYCLO-2-HEPTENE-2-PROPIONALDEHYDE
Description
Tetramethylbicyclo-2-heptene-2-propionaldehyde, also known as Cyclademol or Dupical, is a synthetic fragrance ingredient commonly used in skincare and personal care products. This clear, colorless liquid has a distinct floral, woody scent reminiscent of lily of the valley. Its molecular structure allows for slow evaporation, making it an excellent fixative in fragrance compositions.
In skincare formulations, this ingredient primarily functions as a masking agent, helping to neutralize unpleasant odors from active ingredients. It can enhance the overall sensory experience of products, potentially improving user compliance with skincare regimens. However, it does not provide direct skin benefits.
While generally considered safe for cosmetic use, Tetramethylbicyclo-2-heptene-2-propionaldehyde may cause skin sensitization in some individuals, particularly at higher concentrations. It is typically used at low levels (0.1-1%) in leave-on products and up to 5% in rinse-off formulations. This compound is biodegradable but may pose risks to aquatic organisms if released in large quantities.
Formulators should be aware of regulatory limits and potential allergenicity when incorporating this ingredient. It's crucial to conduct proper safety assessments and patch testing, especially for products intended for sensitive skin.
