Methyl Ionone Gamma A
Odor Description:Floral, Powder/ Powdery, Tobacco, Woody
Pell Wall Perfumes
Methyl ionone iso super
Odor Description:floral-violet, fruity, powdery, woody, tea-like
It is extremely versatile in character, and effects ranging from sweet floral to tobacco-like or woody are obtainable with various grades of subject material. The most refined grades, which are quite expensive, often show a very attractive ‘creamy’ top-note and a most uniform, powdery-sweet dryout performance. This type of Methylionone can support floral notes in Ylang-Ylang as well as woody notes in Vetiver, or leathery notes in Salicylates, etc. Certain types of perfume contain up to 25% or more of this material. Many soap perfumes are based upon a large volume of common-grade Methylonone with the subject isomer as pre-dominant component.” Calkin & Jellinek talk about Methyl Ionone: “Methyl ionone is one of the most versatile materials used in perfumery. Although it occurs in a number of different isomeric forms … the qualities most widely used today are either the gamma (iso-alpha) form or a mixture of isomers in which this predominates. In odor it lies somewhere between floral, woody, and iris, working in a perfume as a bridge between the middle and base notes. It blends with almost every type of material, taking its place as a structural component in many of the great perfume families.”

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.
