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 ( For more details see chapter 1 of the Guidance for the use of IFRA Standards.

Recommendation for (+)-isothujone flavor usage levels up to:
 not for flavor use.

Thujone is a ketone and a monoterpene that occurs naturally in two diastereomeric forms: (-)-alpha-thujone and (+)-beta-thujone. It has a menthol odor. In addition to (-)-alpha-thujone and (+)-beta-thujone, there are their enantiomeric forms, (+)-alpha-thujone and (-)-beta-thujone. (Wikipedia)
