ALDEHYDE C11 UNDECYLENIC – aldehydic, rosy and waxy note with hints of fresh citrus, white wood and soapy rose petals

Fatty, oily, slightly floral when diluted. Citrusy, fresh, floral, ozonic, strong, waxy, rosy, soapy, woody. It reveals a complex of rose and woody aromas. It is used sparingly due to the rose and woody notes in fruity fragrances. Widely used in modern perfumery, particularly effective in floral and spicy blends. The scent has moderate to good longevity and can be classified as one of the prototypes of the term "aldehyde." The material polymerizes in air and forms adducts (addition products) with amines (indole, anthranilates, quinolines, etc.). It is one of the most widely used aliphatic aldehydes, although the concentration in perfume oils is higher than in other products, usually 0.1% to 0.5%. Its unique diffusion ability and the lifting effect it can bring to the scent are also highly valued in soap perfumery. It is used as a carrier note for rose, amber, musk, and many other fragrances and is a very versatile material. It hardens in the cold and melts at 25°C. It polymerizes in air. It has a pleasant, refreshing, waxy-floral flavor with a slight fruity accent and a moderate longevity. It has a fresh, citrusy flavor at concentrations below 10 parts per million. At higher concentrations, the flavor becomes unpleasant unless accompanied by a flavoring. It is widely used in perfumed compositions in very small proportions. Residual amounts, usually less than 0.5%, are used in floral compositions such as rose, tuberose, cassia, jasmine, etc., as well as in "incense" compositions (olibanum), "fresh air perfumes," iris compositions, etc., and in compositions with notes of citrus oils or fruity materials, providing a good carrier for verbena.

Concentrations of 1 to 3 parts per million in ready-made food products are used to imitate lemon, lime, mandarin, orange, cucumber, honey, and various fruity compositions, to add waxy, honeyed, fresh notes, etc. The concentration in chewing gum can reach 50 or 60 parts per million.
