Silvial is a powerful, vibrant muguet ingredient with a slight citrus undertone and a fresh, aldehydic touch that is used in perfumery in the same way as related muguet products. Powerful, Floral, Muguet, Fresh
A popular component of flower compositions, particularly lily of the valley and linden types providing a pleasant blossom odor. Floral, Green, Aldehydic, Marine
Arctander thought the material had potential for wider use: “The title aldehyde, commercially available for some years, has some of the advantages of Cyclamen aldehyde, and some of those of Lilial (Bucinal), its tertiary-Butyl-isomer. It is undoubtedly more versatile than Cyclamen aldehyde, and the perfumer can enjoy using much higher concentrations of this aldehyde, without producing overly green-vegetable notes, etc” Floral-muguet, fresh-marine, aldehydic, green, balsamic

Notes:
IFRA FLAVOR REQUIREMENTS:

Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.

Recommendation for cyclamen homoaldehyde flavor usage levels up to:
not for flavor use.
