Description

6,6-dimethylbicyclo[3,1,1]hept-2-ene-2-propionaldehyde is a fragrance ingredient characterized by a sea breeze aroma with fresh and herbal notes over a subtle pine character. It features an aldehydic effect that enhances the sense of cleanliness in detergents and soaps, bringing freshness to cleaning and personal care products.

Additional information

The chemical structure of 6,6-dimethylbicyclo[3,1,1]hept-2-ene-2-propionaldehyde shares an affinity with natural pine components, which accounts for the characteristic pine aroma it imparts to products. This structural similarity to pine alpha-pinene gives it its distinct aromatic properties.
The aldehydic effect in fragrances became famous with iconic scents like Chanel No. 5, launched in 1921. This effect introduces a characteristic clean, fresh, and slightly metallic note that changed the world of perfumery.
Laboratory fragrance ingredients like this one often have a more consistent scent profile compared to natural extracts, which can vary depending on the season, growing location, and environmental conditions. This consistency allows perfumers to achieve reliable results in every product batch.
